Sour Cream Chocolate Cake

Preparation Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.

Cake Batter In a large mixing bowl, combine the sour cream, sugar, cocoa powder, flour, baking powder, baking soda, salt, butter, eggs, and vanilla extract. Beat on medium speed until well blended. Slowly add the boiling water and mix until smooth.

Baking the Cake Pour the batter evenly into the prepared cake pans. Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean. Remove from the oven and let the cakes cool in the pans for 10 minutes. Transfer to a wire rack to cool completely.

Preparing the Frosting In a medium mixing bowl, cream together the butter and cocoa powder until smooth. Gradually add the powdered sugar, milk, and vanilla extract. Beat until light and fluffy.

Assembling the Cake Place one cake layer on a serving plate and spread a layer of frosting on top. Place the second cake layer on top and frost the top and sides of the cake. Decorate as desired.
