Triple Coconut Cake

I copied this recipe from a magazine. If you like coconut, you will absolutely love this cake. It is fantastic.

1 pkg. Duncan Hines moist deluxe classic white cake mix
1 1/2 cups unsweetened coconut*
4 large egg whites
2 cans Duncan Hines Creamy Home-Style Coconut Supreme Frosting
1 1/2 cups sweetened coconut flakes
1. Preheat oven to 350 degrees. Grease and flour 3 -8in. round baking pans according to package directions.
2. In a large mixing bowl, blend the cake mix, coconut milk* and egg whites. Beat at low speed until moistened. Beat at med. speed for 2 min. Pour batter evenly among the 3 pans and bake for 18-21 min. or until toothpick inserted into the center comes out clean.
3. Cool layers in pan on a wire rack for 15 min. Turn out of pan to cool completely before frosting.
4. Place one layer on a serving plate. Spread a thin layer of coconut frosting on top and sprinkle with 1/4 cup of coconut. Repeat with second layer. Top with the third layer and frost top and sides of cake with remaining frosting. Sprinkle remaining coconut on top and sides of cake.

*Substitution: 1 1/2 cups water, 2 Tbsp. oil and 1/2 tsp coconut extract may be substituted in place of the coconut milk. Makes 12 servings
