Chocolate Fudge Brownie Cake
This Chocolate Fudge Brownie Cake is the ultimate convergence of two classic desserts, featuring the dense, chewy texture of a brownie layered with the airy structure of a traditional fudge cake. The secret to its glass-like finish is a warm chocolate ganache pour, which locks in moisture and provides a sophisticated contrast to the whipped buttercream rosettes.
Ingredients
The Brownie Cake Layers
- 1 cup unsalted butter, melted
- 2 cups granulated sugar
- 4 large eggs, room temperature
- 1 tablespoon pure vanilla extract
- 1 cup all-purpose flour
- ¾ cup unsweetened cocoa powder (Dutch-processed for deeper flavor)
- ½ teaspoon salt
- 1 cup semi-sweet chocolate chips
The Filling & Topping
- 2 cups chocolate buttercream or salted caramel frosting
- ½ cup heavy cream (for ganache)
- 4 oz dark chocolate, finely chopped
- Assorted garnish: chocolate hearts, chips, and brownie chunks
Preparation
1. Bake the Layers
Preheat your oven to 350°F (175°C). In a large bowl, whisk the melted butter and sugar until combined. Add eggs one at a time, followed by vanilla. Sift in the flour, cocoa powder, and salt, folding until just combined. Stir in the chocolate chips. Divide the batter between two greased 6-inch round cake pans and bake for 25–30 minutes until a tester comes out with a few moist crumbs. Cool completely.
2. Assemble the Base
Place the first cooled layer on a cake stand. Pipe a thick, even layer of buttercream across the top, ensuring it reaches the edges to create a stable foundation for the second layer. Place the second brownie cake on top and lightly press to secure.
3. Apply the Fudge Drip
Heat the heavy cream until it just begins to simmer, then pour it over the chopped dark chocolate. Let sit for 5 minutes, then whisk until smooth. Once the ganache is slightly thickened but still pourable, use a spoon or squeeze bottle to create the drip effect around the edges of the cake before filling in the center.
4. Garnish and Set
Using a star tip, pipe rosettes of vanilla or chocolate buttercream around the top perimeter. Arrange chocolate hearts, brownie pieces, and extra chocolate chips into the ganache and frosting. Allow the cake to chill for at least 30 minutes to set the drip before slicing.
Note: Because this cake is incredibly rich and dense, it is best served at room temperature with a splash of cold milk or a scoop of vanilla bean ice cream to balance the deep cocoa notes.
