Total Time: 1 hour 25 minutes
Yield: 1 (9-inch) layer cake
Directions
1. Prep & Base: Preheat your oven to 350°F (175°C). Grease two 9-inch cake pans. Beat the eggs and sugar until thick and smooth, then add the melted butter. Gently fold in the cocoa powder, vanilla, flour, salt, and baking powder until just combined. Divide the batter evenly between the prepared pans.
2. Bake & Cool: Bake the brownie layers for 25-30 minutes, until the edges are set and the center remains slightly fudgy. Insert a toothpick to check; it should come out with a few moist crumbs. Cool the layers completely on a wire rack.
3. Make the Filling: In a saucepan over medium heat, combine ground walnuts, coconut flakes, heavy cream, sugar, and egg yolks. Cook while stirring constantly until thickened, about 10 minutes. Remove from heat and mix in the butter. Allow it to cool.
4. Frosting Time: Beat the softened butter and chilled mascarpone together until fluffy. Gradually incorporate the powdered sugar, vanilla seeds, and a pinch of salt, mixing until creamy and smooth.
5. Assembly: Place one brownie layer on a serving plate, spread half of the coconut-walnut filling over it. Repeat with the second brownie layer and remaining filling. For the finishing touch, pour the slightly cooled chocolate ganache over the top, allowing it to drip decoratively down the sides.
Detailed Directions and Instructions
1. Prep & Base:
Preheat your oven to 350°F (175°C). Grease two 9-inch cake pans generously to ensure easy removal. In a large mixing bowl, beat the eggs and sugar together until the mixture is thick and smooth, resembling a luscious batter. Slowly add in the melted butter, mixing well. Gently fold in the sifted cocoa powder, vanilla extract, all-purpose flour, kosher salt, and baking powder until the ingredients are just combined, ensuring a rich, chocolatey mixture. Divide the batter evenly between the prepared pans.
2. Bake & Cool:
Place the cake pans in the preheated oven and bake for 25-30 minutes. The edges should look set with a slightly fudgy center. You can use a toothpick to check for doneness; it should come out with moist crumbs, indicating a fudgy texture. Allow the layers to cool completely on a wire rack, filling your kitchen with the delightful aroma of freshly baked brownies.
3. Make the Filling:
In a medium saucepan over medium heat, combine the ground walnuts, coconut flakes, heavy cream, sugar, and egg yolks. Stir constantly while cooking this mixture until it thickens, about 10 minutes, forming a creamy filling with a beautiful texture. Once thickened, remove it from the heat and mix in the room temperature butter until melted and smooth. Let the filling cool to room temperature.
4. Frosting Time:
For the frosting, take softened butter and chilled mascarpone cheese in a mixing bowl. Beat them together until light and fluffy, creating a beautifully creamy base. Gradually incorporate the powdered sugar, scraped vanilla bean seeds, and a pinch of salt. Continue mixing until the frosting is silky and smooth, ready to envelop your cake layers.
5. Assembly:
Begin assembling your masterpiece by placing one brownie layer on a serving plate. Spread half of your coconut-walnut filling over this layer, allowing the filling to reach the edges for a visually appealing look. Take the second brownie layer and place it on top, repeating the process with the remaining coconut-walnut filling. For the grand finale, pour the slightly cooled chocolate ganache over the entire cake, enabling it to cascade down the sides in a decadent fashion.

Storage:

Cook Techniques
Layering
Ensure each brownie layer is evenly baked before stacking. Use a leveler if necessary to achieve flat surfaces for a stable cake structure.
Cooling
Let brownie layers cool completely on a wire rack to prevent melting the frosting during assembly. This ensures a clean, well-defined look.
Making Ganache
Heat heavy cream until just boiling, then pour it over chopped chocolate. Let it sit for a few minutes before stirring until smooth.
Frosting Consistency
Aim for a creamy frosting consistency by gradually adding powdered sugar. If too thick, add a splash of milk to reach the desired texture.
Filling Technique
Spread the coconut-walnut filling evenly using an offset spatula for a smooth application between layers.
Dripping Ganache
Allow the ganache to cool slightly before pouring over the cake. This helps control the drip effect, ensuring it doesn’t run off too quickly.
