I make a chocolate cream cheese frosting with this to make cake pops.
CHOCOLATE CAKE
2 1/2 cups all-purpose flour
1 cup unsweetened cocoa powder
1 teaspoon baking soda
2 teaspoons baking powder
1/2 teaspoon salt
1 cup (250 grams) butter, at room temperature
2 cups sugar
3 eggs, at room temperature
1 teaspoon vanilla extract
1 1/2 cups milk, at room temperature
Preheat oven to 180 degrees C. Grease and flour a 9-by-13 inch cake pan.
In a medium bowl, sift together the flour, cocoa powder, baking soda, baking powder, and salt. Set aside.
In a large bowl cream the butter and sugar for 5 minutes or until light and fluffy.
Add the eggs, one at a time, to the creamed sugar and butter, mixing until just combined. Scrape down the sides of the bowl after each addition. Add the vanilla and mix until combined.
Add the flour mixture, a third at a time, alternating with the milk in two additions. (You'll begin and end with the flour mixture.)
Spread the batter (it will be thick) evenly into prepared pan.
Bake for 35 to 40 minutes, or until a toothpick inserted in the center comes out clean.
