Ingredients

To create this sumptuous Chocolate Brownie Cake, you’ll need:

8 large eggs – Fresh and light, these eggs provide the perfect texture.
3 cups sugar – Sweet and crystalline, working in harmony to amplify the chocolate flavor.
16 ounces melted butter – Rich and creamy, this butter ensures your cake is moist and decadent.
1 1/2 cups cocoa powder, sifted – Deeply chocolatey and aromatic, this ingredient is the heart of the cake.
1 teaspoon vanilla extract – A splash of sweetness that enhances the overall flavors.
1 1/4 cups flour, sifted – Adds structure and a slight chewiness to the brownie layers.
1/2 teaspoon kosher salt – Balances sweetness and amplifies flavor.
1 teaspoon baking powder – Provides just the right amount of lift for a delectable crumb.
1 cup walnuts, finely ground – Adds delightful texture and a nutty flavor.
1 1/2 cups coconut flakes (unsweetened or sweetened) – Sweet, chewy shreds that add a tropical twist.
1 cup heavy cream – A thick, luscious base for the coconut filling.
1 cup sugar (for coconut filling) – Sweetens the coconut filling to perfection.
3 egg yolks – Enriches the filling with a creamy texture.
5 tablespoons unsalted butter, room temperature – Adds silkiness to the coconut filling.
3 sticks unsalted butter, softened (for buttercream) – The foundation of a creamy, dreamy buttercream frosting.
8 ounces mascarpone cheese, chilled – Rich, velvety cheese that makes the buttercream luxurious.
2 1/2 cups powdered sugar – Light and fluffy, it sweetens the buttercream without making it too dense.
1 vanilla bean, seeds scraped – Layers in an aromatic depth for the buttercream.
Pinch of salt – A small touch that elevates the entire buttercream flavor.
8 ounces semisweet chocolate, chopped (for ganache) – Deep and rich, this chocolate makes for an irresistible topping.
2 tablespoons light corn syrup – Adds sheen and prevents the ganache from hardening.
1 cup heavy cream (for ganache) – Creates a rich and creamy smooth texture for the ganache.

Step-by-Step Directions

Preheat your oven to 350°F (175°C). Grease and line two 9-inch round cake pans with parchment paper to ensure easy removal.
In a mixing bowl, whisk the eggs and sugar together until they become frothy. Stir in the melted butter and vanilla extract. Gradually add the sifted cocoa powder, flour, salt, and baking powder. Mix gently until just combined, being careful not to overmix. Divide the batter equally between the two pans and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Allow the cakes to cool completely in the pans before transferring them to a cooling rack.
For the coconut filling, combine heavy cream and sugar in a saucepan and heat until the sugar is fully dissolved. In a separate bowl, whisk the egg yolks, then temper them by gradually adding the warm cream mixture. Return to the heat and cook over low heat until thickened. Stir in the finely ground walnuts, coconut flakes, and room temperature butter. Cool the filling completely before using.
To prepare your buttercream, beat the softened unsalted butter in a mixing bowl until smooth and creamy. Add the chilled mascarpone cheese, powdered sugar, vanilla bean seeds, and a pinch of salt. Beat on high speed until fluffy and well combined.
To assemble your Chocolate Brownie Cake, place one brownie layer on a serving plate. Spread half of the coconut filling evenly over the first layer. Gently place the second brownie layer on top and spread the remaining coconut filling over this layer. Finish by coating the entire cake with a generous layer of buttercream.
For the ganache, combine the chopped semisweet chocolate and light corn syrup in a heatproof bowl. In a saucepan, heat the heavy cream until it reaches a simmer. Pour the hot cream over the chocolate and let it sit for a minute before stirring gently until smooth and glossy.
Finally, pour the ganache over the assembled cake, allowing it to cascade down the sides. Let the ganache set before slicing the cake into pieces and serving to your eager guests.
