A simple recipe for chocolate brownie cake was published by Emeril Lagasse. The recipe requires a variety of ingredients but is relatively simple to produce, and it feeds 10 to 12 people.
To make Lagasse's brownie cake recipe, begin by greasing two 9-inch cake pans and then lining them with flour and parchment. Next, cream 1/2 pound of softened butter and 2 cups of sugar in an electric mixer until they are light and fluffy. Then thoroughly mix in 2 eggs. In a medium mixing bowl, add 2 cups of flour, 1 teaspoon of baking soda and 4 tablespoons of cocoa powder. Sift these thoroughly. After this, whisk 1/2 cup of buttermilk, 1/2 cup of sour cream and 1 teaspoon of vanilla extract together in a small mixing bowl.
Then add the dry ingredients in three batches to the mixer, set on low speed, alternating with the liquid ingredients. Following this, evenly distribute the cake batter among the two cake pans, and bake until the cake is sufficiently hardened, which should take between 30 to 35 minutes. Remove the cakes from the oven, and allow them to cool. When the cakes are completely cooled, apply a frosting of your choice.
