Kimmy'S Chocolate Guinness Cake - cooking recipe

Ingredients

butter, for pan
2 cups Guinness stout
20 tablespoons unsalted butter
1 1/2 cups unsweetened cocoa
4 cups granulated sugar
1 1/2 cups sour cream
4 large eggs
2 tablespoons vanilla extract
4 cups all-purpose flour
5 teaspoons baking soda
2 (16 ounce) vanilla frosting

Preparation

Heat oven to 350 degrees.
Butter (2) 9-inch springform pans.
In a large saucepan, combine Guinness and butter. Place over medium heat until butter melts. Add cocoa and sugar. Whisk to blend.
In another bowl, combine sour cream, eggs and vanilla; mix well. Add to Guinness mixture. Slowly incorporate the flour and baking soda, and whisk again until smooth. Divide into the two buttered pans, and bake until risen and firm, approximately 45 minutes.
Place pan on a wire rack and cool completely in pan. Meanwhile, stir in a bit of cocoa powder to the vanilla frosting. Once the cakes have cooled, remove from the pans and frost the top of one of the cakes. Place the other cake on top and complete frosting the entire cake.
