Paula Deen's Chocolate Sour Cream Pound Cake

Mike's birthday is tomorrow, so what could be better than this? I hope he likes it!

2 sticks butter, softened
8 oz sour cream
3 c. Sugar
6 eggs
1 t. Vanilla
2 1/4 c. Cake flour
1 t. Baking powder
3/4 c. Cocoa

Preheat oven to 325 degrees. Grease and flour a 10 in. bundt pan. Using mixer, cream together the butter, sour cream, and sugar. Add the eggs, 2 at a time, beating well after each addition. Add the vanilla. In another bowl, stir together the flour, baking powder, and cocoa. Add half the flour mixture to the creamed mixture, beat well, add remaining flour mixture and continue beating for 2 minutes. Pour the batter into prepared pan. Bake 1 hour 15 minutes. Do not open the oven to check the cake for at least an hour. I dusted the cake with powdered sugar.
