👩‍🍳 Instructions

1️⃣ Make the Brownie Cake Layers

Preheat oven to 350°F (175°C).
Line three 8-inch cake pans with parchment paper.
Mix melted butter, granulated sugar, and brown sugar until smooth.
Add eggs and vanilla; whisk until glossy and well mixed.
Add cocoa powder, flour, and salt; stir gently until combined.
Fold in chocolate chunks or chips.
Divide batter into the three pans.
Bake for 20–25 minutes, until set but still fudgy.
Cool completely before assembling.

2️⃣ Make the Chocolate Filling

Beat heavy cream until stiff peaks form; set aside.
In another bowl, beat cream cheese, powdered sugar, and vanilla until smooth.
Fold whipped cream into the cream cheese mixture.
Fold in mini chocolate chips.
Chill filling for 20 minutes to thicken.

3️⃣ Make the Ganache

Heat heavy cream until steaming (do not boil).
Pour over the chocolate chips.
Let sit for 3 minutes, then stir until smooth, thick, and glossy.
Allow to cool slightly so it becomes spreadable, not runny.

4️⃣ Assemble the Cake

Place the first brownie layer on a serving plate.
Spread a thick layer of chocolate filling.
Add the second brownie layer.
Add more filling.
Top with the final brownie layer.
Pour warm ganache over the top, letting it drip naturally down the sides.
Decorate with mini cookies, truffles, and extra ganache drizzles for the perfect chocolate overload look.

⭐ Serving

Chill the cake for 1 hour before slicing for clean, defined layers.
Serve with cold milk or a scoop of vanilla ice cream for the ultimate flavor combination.

🧊 Storage

Refrigerator: Up to 5 days
Freezer: Freeze slices for up to 2 months (wrap tightly)

❓ Frequently Asked Questions (FAQ)

1. Can I bake the brownie layers in one pan and slice them?

You can, but baking in three pans ensures even, fudgy layers without overbaking.

2. Can I use boxed brownie mix instead of homemade?

Yes! Use two family-size brownie mixes and divide among three pans.

3. Why did my ganache turn grainy?

The chocolate may have overheated. Gently rewarm with a splash of cream and whisk until smooth.

4. Can I make the cake ahead of time?

Yes — assemble the cake and store it in the fridge for up to 24 hours before serving. Add toppings right before serving.

5. Can I use milk chocolate instead of semi-sweet?

Yes, but reduce the cream slightly since milk chocolate is softer.

6. My filling is too soft — what should I do?

Chill it longer. Cream-based fillings thicken significantly after 20–40 minutes.

7. Can I add more mix-ins to the layers?

Absolutely — chopped Oreos, brownie chunks, or caramel bits all work beautifully.
