Planning Your Design

Planning and sketching your unicorn cake design is a creative and fun process that allows you to visualize the final product before you start baking and decorating. Here’s a guide to help you through the planning and design phase, focusing on sketching your cake and choosing a color palette.

1. Gather Inspiration

Before you start sketching, look for inspiration. Social media platforms, baking blogs, and Pinterest are great places to find images of unicorn cakes. Notice the elements you like in each design, such as the color schemes, decorations (like flowers or stars), and the style of the unicorn’s features (eyes, ears, horn).

2. Sketching Your Unicorn Cake

  • Outline the Shape: Start with a simple outline of the cake layers. Unicorn cakes are typically round and can vary in the number of layers depending on how tall you want your cake to be.
  • Add the Unicorn Elements: Sketch the position of the unicorn’s horn, ears, and eyes. Decide if you want the horn and ears to be on top of the cake or if the ears will be partially embedded into the top layer. For the eyes, consider their shape and expression.
  • Decorative Elements: Think about additional decorative elements like flowers, stars, or rainbows. Sketch where these elements will be placed around the cake.
  • Final Touches: Add any final touches to your sketch, such as a mane or tail, which can be piped around the edges or the back of the cake.

3. Choosing Your Color Palette

  • Main Colors: Decide on the main colors for your cake. Traditional unicorn cakes often feature pastel shades, but you can choose any colors that fit your theme or preference.
  • Accent Colors: Select accent colors for smaller details like the horn, eyes, and decorative elements. Metallic colors like gold or silver can add a magical touch to the horn and ears.
  • Harmony: Ensure your chosen colors work well together. Use a color wheel to help you find complementary or analogous color schemes that will make your cake visually appealing.
  • Test Your Colors: If you’re using fondant or buttercream, consider doing a small test to see how your colors look when mixed and applied. This can help you adjust the shades before you start decorating the actual cake.

4. Finalizing Your Design

Review your sketch and color choices, making any final adjustments. Consider the size of the cake and the proportion of the decorations to ensure everything will look balanced once assembled. This is also a good time to make a list of all the materials and colors you’ll need for baking and decorating.

5. Execution Plan

With your design planned and sketched, create a step-by-step plan for baking, assembling, and decorating your cake. This will help ensure a smooth process and reduce the likelihood of missing any important details.

By carefully planning and sketching your unicorn cake design and thoughtfully choosing your color palette, you’ll be well-prepared to create a beautiful and magical cake that’s sure to impress.

Baking the Perfect Cake

Baking the perfect cake is both an art and a science. It requires precision, patience, and a bit of creativity. Here’s a comprehensive guide to help you bake a cake that’s moist, fluffy, and delicious every time.

Ingredients at Room Temperature

  • Start with Ingredients at Room Temperature: Ingredients like butter, eggs, and milk should be at room temperature. This ensures they mix together more uniformly, resulting in a smoother batter and a more evenly baked cake.

Measuring Ingredients

  • Measure Accurately: Use measuring cups for dry ingredients and a liquid measuring cup for wet ingredients. For more precision, consider using a kitchen scale to measure ingredients by weight.
  • Sift Dry Ingredients: Sifting flour and other dry ingredients helps remove lumps and aerates the mixture, leading to a lighter cake texture.

Mixing the Batter

  • Don’t Overmix: Mix the batter just until the ingredients are combined. Overmixing can develop the gluten in the flour, leading to a dense, tough cake.
  • Scrape the Bowl: Use a spatula to scrape down the sides of the bowl periodically. This ensures all ingredients are well-incorporated.

Preparing the Cake Pans

  • Proper Pan Preparation: Grease the cake pans and line the bottom with parchment paper. This prevents the cake from sticking and ensures easy removal after baking.
  • Even Batter Distribution: Divide the batter evenly between the pans to ensure uniform baking. Use a kitchen scale for accuracy.

Oven Temperature and Position

  • Preheat the Oven: Always preheat your oven to the temperature specified in the recipe. An oven thermometer can help ensure accuracy.
  • Center Position: Place the cake pans in the center of the oven. If baking multiple pans at once, ensure there’s enough space between them for air circulation.

Baking and Testing for Doneness

  • Baking Time: Follow the recipe’s recommended baking time, but start checking for doneness a few minutes before it’s supposed to be done.
  • Test for Doneness: Insert a toothpick or cake tester into the center of the cake. If it comes out clean or with a few moist crumbs attached, the cake is done.
  • Avoid Opening the Oven Frequently: Opening the oven door can cause temperature fluctuations that affect the cake’s rise and texture.

Cooling and Unmolding

  • Cooling: Let the cake cool in the pan on a wire rack for the time specified in the recipe, then remove it from the pan to cool completely. Cooling helps set the cake’s structure.

Frosting and Decorating

  • Completely Cool Before Frosting: Frosting a warm cake can lead to melted frosting and crumbs throughout your icing. Ensure the cake is completely cool before beginning to decorate.

Storage

  • Storing the Cake: If not serving immediately, store the cake properly to maintain its freshness. An unfrosted cake can be wrapped in plastic wrap and stored at room temperature for several days or frozen for longer storage. Frosted cakes should be stored in the refrigerator and brought to room temperature before serving.

By following these tips and techniques, you’ll be well on your way to baking the perfect cake. Remember, practice makes perfect, so don’t be discouraged by any mishaps. Each baking experience is a learning opportunity.

Preparing Your Buttercream

Before you begin to decorate your unicorn cake with buttercream, ensure your cake layers are cooled and ready. is a crucial step in cake decorating, providing both a delicious flavor and a smooth, versatile base for decorating. Here’s a guide to making a basic buttercream that’s perfect for spreading, piping, and creating a flawless finish on your cakes. consider revisiting our guide on how to make a unicorn cake, which provides foundational steps for creating a stable and delicious base.

Ingredients:

  • 1 cup (2 sticks or 226 grams) unsalted butter, softened
  • 4 cups (480 grams) powdered sugar, sifted
  • 2-3 tablespoons heavy cream or milk
  • 2 teaspoons pure vanilla extract
  • A pinch of salt (optional)

Instructions:

1. Prepare Your Ingredients

  • Ensure the butter is at room temperature to achieve a smooth, creamy texture.
  • Sift the powdered sugar to remove any lumps, which will ensure a smoother buttercream.

2. Beat the Butter

  • In a large mixing bowl, use an electric mixer to beat the butter on medium speed until it is creamy and lightened in color, about 2-3 minutes. This process incorporates air into the butter, making the buttercream fluffy.

3. Gradually Add Powdered Sugar

  • Gradually add the powdered sugar, one cup at a time, beating on low speed until the sugar is fully incorporated before adding the next cup. This gradual process helps prevent the powdered sugar from flying everywhere and ensures a smooth consistency.

4. Add Liquid Ingredients

  • Once all the powdered sugar has been incorporated, add the vanilla extract and 2 tablespoons of heavy cream or milk. Beat on medium speed for about 1 minute. The mixture should be smooth and spreadable.
  • If the buttercream is too thick, add more cream or milk, one tablespoon at a time, until you reach the desired consistency. If it’s too thin, add a little more powdered sugar until it thickens up.

5. Adjust Flavor and Consistency

  • Taste the buttercream and adjust as necessary. If you’re using unsalted butter and find the buttercream too sweet, a pinch of salt can help balance the flavors.
  • For a thinner consistency, particularly if you’re using the buttercream for a crumb coat or a smooth finish, you can add a bit more cream or milk. For piping decorations, you might prefer a slightly stiffer buttercream.

6. Coloring Your Buttercream

  • If you plan to color your buttercream, add the food coloring a little at a time, mixing thoroughly after each addition, until you achieve the desired color. Gel food coloring is recommended because it provides intense color without adding too much liquid to the buttercream.

you might find additional tips in our article on unicorn cakes’ popularity and trend, which touches upon the importance of color in unicorn cake design.

7. Use or Store

  • Your buttercream is now ready to use. If not using immediately, it can be stored in an airtight container in the refrigerator for up to a week. Before using, let it come to room temperature and re-whip it to bring back its creamy texture.

This basic buttercream recipe can be customized in many ways. Experiment with different extracts, zests, or even melted chocolate to create a variety of flavors. Enjoy the process of making your buttercream as much as you enjoy using it to decorate your delicious cakes!

Basic Techniques for Buttercream Decoration

Buttercream decoration is an art that can transform simple cakes into stunning masterpieces. Whether you’re a beginner or looking to refine your skills, mastering some basic techniques can significantly enhance your cake decorating. Here’s a guide to fundamental buttercream decoration techniques:

1. Smooth Coating

A smooth buttercream finish is the foundation of cake decorating. It requires patience and practice to perfect.

  • Tools: Offset spatula, bench scraper, turntable.
  • Technique: Apply a generous amount of buttercream to the top and sides of your cake. Use an offset spatula to spread the buttercream evenly. Then, hold a bench scraper against the cake’s side while rotating the turntable to smooth the sides. Use the spatula to smooth the top, pulling inwards from the edges.

2. Piping Borders

Piping borders can add elegance and finish to your cake.

  • Tools: Piping bags, piping tips (star, round, shell).
  • Technique: Fill a piping bag fitted with your chosen tip with buttercream. Practice piping on parchment paper before moving to the cake. Keep consistent pressure for an even border. Common patterns include shells, stars, and rosettes.

3. Writing on Cakes

Writing messages on cakes is a cherished tradition.

  • Tools: Piping bag, small round tip (e.g., #2 or #3).
  • Technique: Thin your buttercream slightly so it flows easily. Practice your message on parchment paper. When ready, gently squeeze the piping bag and use steady, even pressure to write. Keep the tip slightly above the cake surface to avoid dragging.

4. Creating Rosettes

Rosettes are beautiful and can cover a cake entirely or be used as accents.

  • Tools: Piping bag, star tip (e.g., 1M or 2D).
  • Technique: Hold the piping bag perpendicular to the cake surface. Squeeze to form a tight center, then slowly rotate the tip in a circle around the center until the rosette is complete. Release pressure to end.

5. Making Leaves

Leaves add a natural touch to floral designs.

  • Tools: Piping bag, leaf tip.
  • Technique: Fill the piping bag with green-tinted buttercream. Position the tip where you want the leaf to start, squeeze to adhere, then release pressure as you pull away, tapering off to form the leaf tip.

6. Textured Effects

Textured effects can add depth and interest to your cake.

  • Tools: Various spatulas, forks, or even paper towels.
  • Technique: Apply a base layer of buttercream. Then, use your tool of choice to create patterns. For example, a small spatula or the back of a spoon can create swirls, while a fork can create lines or waves.

7. Ombre Effect

The ombre effect is a beautiful way to add color to your cake.

  • Tools: Offset spatula, bench scraper.
  • Technique: Apply layers of buttercream in gradually darkening shades of the same color from bottom to top. Use a bench scraper to blend the colors where they meet slightly for a smooth transition.

Crafting the Unicorn Features

Crafting the unicorn features for your cake involves a mix of creativity, precision, and a bit of whimsy. The main features of a unicorn cake typically include the horn, ears, and eyes, with optional additions like flowers, stars, or a mane. Here’s how to create these magical elements:

1. Unicorn Horn

The horn is the centerpiece of your unicorn cake and can be made from fondant or modeling chocolate.

  • Materials: Fondant (white or colored), edible gold or silver paint (optional), skewer or lollipop stick.
  • Technique: Roll a piece of fondant into a long, thin rope, tapering one end to a point. Twist it around a skewer or lollipop stick, starting with the thicker end at the bottom. Allow it to dry completely, ideally overnight. Once dry, you can paint it with edible gold or silver paint for a magical touch. Insert the skewer into the top of the cake, ensuring the horn stands upright.

2. Ears

Unicorn ears are usually made from fondant, with a pink inner ear for a pop of color.

  • Materials: White and pink fondant.
  • Technique: Roll out white fondant and cut out two ear shapes using a knife or a cookie cutter. Repeat with pink fondant, but make these cuts slightly smaller. Attach the pink fondant to the center of the white pieces using a bit of water or edible glue. Pinch the bottom of each ear to create a slight fold, giving them a more realistic shape. Allow them to harden a bit before inserting them into the cake, using toothpicks or spaghetti for support if necessary.

3. Eyes

The eyes give your unicorn cake character and personality. They’re typically closed, with long, curled eyelashes for a dreamy look.

  • Materials: Black fondant or edible black marker.
  • Technique: If using fondant, roll out a small amount and cut out the shape of the eyes, including eyelashes. You can also roll tiny pieces of fondant into thin ropes and shape them into eyelashes, attaching them to the cake with a bit of water. Alternatively, use an edible black marker to draw the eyes directly onto the cake, starting with a curved line for the closed eye and adding several lashes.

4. Decorative Elements

Add flowers, stars, or a colorful mane to your unicorn cake for extra whimsy.

  • Flowers: Use fondant or buttercream to create flowers. For fondant flowers, roll out colored fondant and use flower cutters to create various shapes. For buttercream flowers, use a flower nail and piping tips to pipe roses, daisies, or any flower you like, then carefully place them on the cake.
  • Stars: Roll out colored fondant and use a small star cutter to create stars. Attach them to the cake with a bit of water.
  • Mane: Pipe buttercream rosettes, stars, and swirls along the top and down one side of the cake to create a flowing mane. Use a variety of colors for a vibrant effect.

Tips for Success

  • Plan Ahead: Sketch your design first and decide on the placement of each feature.
  • Dry Time: Allow fondant pieces to dry and harden before assembling them on the cake.
  • Support: Use toothpicks, spaghetti, or skewers to support fondant pieces on the cake.
  • Creativity: Feel free to personalize your unicorn cake with different colors, patterns, and additional decorative elements.

Crafting unicorn features for your cake is a delightful process that allows for a lot of creativity. Enjoy the process, and don’t be afraid to add your unique touch to make your unicorn cake truly magical.

How to Decorate a Unicorn Cake with Buttercream?

Decorating a unicorn cake with buttercream is a fun and creative process that allows for a lot of personalization. Here’s a step-by-step guide to help you create a magical unicorn cake using buttercream frosting.

Supplies Needed:

  • A cake (round cakes of varying sizes stacked are most common)
  • Buttercream frosting (ensure you have enough to cover the cake and for the decoration; consider making different colors)
  • Piping bags
  • Piping tips (star tip for the mane, small round tip for the eyes, leaf tip for the ears)
  • Food coloring (for the mane and any other decorative elements)
  • Offset spatula or cake smoother
  • Turntable (optional but helpful)

1: Prepare Your Cake

  • Level and Stack: Begin by leveling your cakes and stacking them with a layer of buttercream between each layer. A three-layer cake is a good starting point for a standard-sized unicorn cake.
  • Crumb Coat: Apply a thin layer of buttercream over the entire cake. This is your crumb coat, which helps to seal in crumbs. Chill the cake in the refrigerator for about 30 minutes to set the crumb coat.

2: Apply the Final Coat

  • Smooth Frosting: Apply a generous layer of buttercream over the crumb coat. Use an offset spatula to spread it evenly over the top and sides. A cake smoother or bench scraper can help achieve a smooth finish. For a unicorn cake, a white or pastel-colored base is typical.
  • Chill Again: Place the cake back in the refrigerator for another 30 minutes to set the final coat of buttercream.

3: Decorate with Buttercream

The Mane

  • Color the Buttercream: Divide your remaining buttercream into portions and color each portion with your chosen colors for the mane.
  • Prepare Piping Bags: Fill separate piping bags fitted with star tips with each color of buttercream.
  • Pipe the Mane: Starting from the top of the cake, pipe swirls, rosettes, and stars down one side to create the mane. Alternate colors as you go to create a vibrant, magical effect.

The Ears

  • Shape the Ears: If you haven’t made fondant ears, you can pipe them with buttercream. Use a thicker consistency buttercream colored with a bit of pink for the inner ear and white for the outer ear. Pipe a large leaf shape for the outer ear and a smaller one inside for the inner ear. You can do this directly on the cake or on parchment paper, then transfer them to the cake once set.

The Horn

  • Create the Horn: For a buttercream horn, you can either pipe a spiral on a cone-shaped piece of cake or use a fondant horn as described in previous instructions. If piping, use a small round tip and start at the base, piping a spiral upwards.

The Eyes

  • Pipe the Eyes: Use black buttercream or a small amount of dark-colored buttercream in a piping bag with a small round tip. Pipe closed eyelashes starting from the middle of the cake’s side, flicking outward to create a gentle curve.

Step 4: Add Final Touches

  • Add Details: You can add more details like flowers, stars, or hearts around the mane or on the cake’s body using different colors and piping tips.
  • Refrigerate: Once decorated, refrigerate the cake until it’s time to serve. This helps the buttercream decorations set and makes the cake easier to cut.

Tips for Success

  • Practice Piping: If you’re new to piping, practice on parchment paper before starting on the cake.
  • Be Creative: Feel free to adjust colors and designs based on your preference or the occasion.
  • Temperature Matters: Work in a cool environment if possible, as buttercream can soften quickly.

Decorating a unicorn cake with buttercream is a delightful project that’s sure to impress. With a bit of practice and creativity, you can create a whimsical and delicious centerpiece for your next celebration.

FAQs

What’s the best buttercream to use for a unicorn cake?

Swiss Meringue Buttercream is often recommended for unicorn cakes due to its smooth, silky texture and not-too-sweet taste. It’s great for creating a smooth base and intricate piped details. However, American Buttercream is also popular for its simplicity and sweetness. Choose based on your preference for taste and texture, as well as your comfort level with making each type.

How do I ensure my cake layers are even and stable?

  • Level Your Cakes: Use a cake leveler or a serrated knife to trim the tops of your cakes to make them flat and even.
  • Use Cake Boards: Place each layer on a thin cake board or cardboard cutout for added stability, especially for taller cakes.
  • Chill Your Layers: Refrigerating your cake layers before assembly can make them firmer and easier to handle, reducing the chances of the cake sliding.
  • Even Spreading: Apply an even layer of buttercream or filling between each layer to prevent unevenness.
  • Dowels for Support: For taller cakes, consider using dowels or straws inserted into the cake to support the structure.

Can I make the horn and ears in advance?

Yes, it’s actually recommended to make the horn and ears in advance. Fondant and gum paste need time to dry and harden, ensuring they hold their shape when placed on the cake. Make these elements at least 24-48 hours before you plan to decorate your cake.

How do I achieve vibrant colors in my buttercream?

  • Gel Food Coloring: Use gel food coloring instead of liquid, as it’s more concentrated and won’t thin out your buttercream.
  • Color Intensity: Start with a small amount and gradually add more until you achieve the desired shade. Remember, the color can deepen over time.
  • White Base: If you’re starting with a vanilla buttercream, ensure it’s as white as possible to get true-to-color results. Adding a tiny bit of purple can help neutralize any yellow tint from the butter.

What’s the secret to smooth buttercream surfaces?

  • Hot Water Method: Dip your spatula or bench scraper in hot water, dry it quickly, and then smooth the buttercream. The heat helps to slightly melt the buttercream, creating a smoother surface.
  • Parchment Paper: Lay a piece of parchment paper over the buttercream and gently smooth over it with your hands or a fondant smoother. This can help achieve a flawless finish.
  • Chill and Smooth: After applying your final coat of buttercream, chill the cake for about 10-15 minutes, then use a spatula or bench scraper to smooth any imperfections.

How can I add sparkle to my unicorn cake?

  • Edible Glitter or Dust: Sprinkle edible glitter or dust over the cake for a magical sparkle. Gold or silver works well for a luxurious effect.
  • Luster Spray: Use an edible luster spray for an all-over shimmer. These sprays come in various colors and can be used to highlight specific areas or the entire cake.
  • Decorative Elements: Incorporate sparkling sugar, pearlescent edible beads, or metallic dragees into your design for added texture and shine.

Creating a unicorn cake is a delightful process that combines baking skills with creativity. By following these tips and allowing yourself to experiment, you can create a beautiful and magical unicorn cake that’s sure to dazzle at any celebration.
