Happy Birthday Cake

Happy Birthday to Justin Timberlake. I wonder if it was every birthday that his grandma would make this coconut cake for him or if it was only for now and then. I hope you enjoy the recipe

Justin Timberlake's Granny's Coconut Cake

• 1 (18.25-oz.) white cake mix
• 8 oz. sour cream
• 1-1/2 c. sugar
• 3 (7-oz) packages sweetened, flake coconut

Prepare cake mix according to package directions, using two 8- or 9-inch round pans. Once cakes are cool, slice in half to form four layers.
In a bowl, mix together sour cream, sugar, and 2 of the packages of coconut. Place one cake layer on a serving plate. Ice the top with the coconut mixture. Repeat with the next two layers. Place the last layer on top and cover entire cake with remaining icing.
Sprinkle some of the coconut from the third package on the top of the cake. Apply the rest to the sides, patting it on with the palm of your hand. Keep the cake in a cool place or refrigerate.
Bring to room temperature before serving.
