This Homemade Fudgy Chocolate Brownie Cake Recipe combines everything you love about brownies and chocolate cake in one easy dessert. It has a rich, fudgy center but bakes into a cake you can slice and serve.
Preheat oven to 350°F (175°C). Grease a 9-inch round cake pan, line the bottom with parchment paper, and lightly grease the sides.
In a small saucepan or using the microwave over low heat, melt the butter and dark chocolate together, stirring gently until smooth. Remove from heat and let cool slightly.
1/2 cup unsalted butter, 1/2 cup dark chocolate
In a large bowl, whisk together the cocoa powder, baking powder, and salt. Pour in the melted butter-chocolate mixture and the hot coffee. Stir until thick, smooth, and fully combined.
1/2 cup Dutch-processed cocoa powder, 1/2 teaspoon baking powder, 1/4 teaspoon salt, 1/2 cup freshly brewed hot coffee
Add the sugar, eggs, and vanilla. Whisk until well combined and slightly glossy.
Let the ganache sit at room temperature for around 60 minutes, stirring occasionally, until thickened to a soft, spreadable consistency. It will thicken as it cools.
Spread the ganache evenly over the cooled cake using an offset spatula or the back of a large spoon for swirls.
Notes
Expert Tips
Use room temperature eggs for smoother mixing and better structure.
Stop baking as soon as moist crumbs appear to keep the cake fudgy.
For best results, let the ganache cool slightly before spreading to avoid a runny finish.
Use an offset spatula for clean edges and smooth sides of the cake.
Slice with a warm knife for neat layers and clean presentation.
