Ingredients
Scale
Brownie Layers
- 1 1/2 cups (340g) unsalted butter, melted
- 1 1/2 cups (300g) granulated sugar
- 1 1/2 cups (300g) light brown sugar, packed
- 6 large eggs, room temperature
- 1 tablespoon vanilla extract
- 1 cup (80g) unsweetened cocoa powder (preferably Dutch-processed)
- 1 teaspoon fine sea salt
- 1 3/4 cups (210g) all-purpose flour
Frosting
- 1 cup (227g) unsalted butter, room temperature
- 8 oz (226g) cream cheese, room temperature
- 6 cups (720g) powdered sugar
- Tiny pinch of salt
- 1/4 cup (60mL) heavy whipping cream, room temperature (reserve 1 tablespoon for chocolate frosting)
- 2 teaspoons vanilla bean paste
- 1/4 cup (20g) unsweetened cocoa powder
Instructions
- Make the Brownie Batter: Melt the butter and mix it thoroughly with both sugars and the eggs in a large bowl. Beat until the mixture becomes pale, fluffy, and ribbons off the whisk, which helps incorporate air and structure.
- Incorporate Dry Ingredients: Add the cocoa powder and salt, whisking again until the mixture becomes dark and glossy. Stir in the flour just until combined to prevent overmixing and maintain a fudgy texture.
- Bake the Brownies: Spread the batter evenly in a greased and parchment-lined 11×15 inch sheet pan. Bake at 325°F (163°C) for about 25 minutes until the edges are set and the center is no longer wet but still soft to the touch.
- Cool and Cut Layers: Allow the brownies to cool for 30–60 minutes, then refrigerate for easier cutting. Using a 6-inch cake ring or template, cut four round layers and set aside the scraps for layering.
- Prepare the Frosting: Whip the butter until pale and fluffy, then add the cream cheese and blend until smooth. Gradually mix in the powdered sugar and a pinch of salt, followed by the heavy cream and vanilla bean paste until fluffy and spreadable.
- Make the Chocolate Frosting: Take one-third of the prepared frosting and mix in cocoa powder and the reserved tablespoon of cream. Stir until smooth to create the chocolate layer.
- Assemble the Cake: Place one brownie round on a flat surface. Spread a layer of chocolate frosting, top with brownie chunks, and then a layer of vanilla frosting. Add the next brownie round and repeat the process until all layers are stacked.
- Frost and Decorate: Frost the entire cake with the remaining vanilla frosting. Add dabs of chocolate frosting around the cake and swirl gently to create a marbled effect. Top with leftover brownie chunks for extra texture.
Notes
- Chill the frosting slightly if it becomes too soft while assembling.
- For cleaner cuts, refrigerate the assembled cake for at least an hour before slicing.
- You can also freeze individual slices for easy portioning later.
- If you prefer a less sweet finish, reduce powdered sugar or substitute with Swiss meringue buttercream.
