Coconut-Pecan Coffee Cake

Preheat oven to 325°F. Grease and flour a 10-inch fluted tube pan; set aside. In a large mixing bowl beat butter with an electric mixer on medium speed for 30 seconds. Add the sugar, baking powder, baking soda, and salt. Beat until well combined, scraping sides of bowl occasionally. Add eggs, one at a time, beating well after each addition. Beat in vanilla. Alternately add flour and sour cream, beating on low speed after each addition just until combined.

Sprinkle half of the Coconut-Pecan Topping in the prepared pan. Spoon half of the batter in mounds over the coconut mixture; carefully spread evenly. Sprinkle with remaining Coconut-Pecan Topping. Spoon on remaining batter, spreading evenly.

Bake for 55 to 65 minutes or until a wooden toothipck inserted near the center comes out clean. Cool in pan on a wire rack for 10 minutes. Remove cake from pan; cool completely on wire rack. If desired, dust cake with a mixture of powdered sugar and cocoa powder.
