Prepare a white cake mix according to the box directions for cupcakes. Allow to cool before frosting. You could also make a large cake and use the same frosting.
7 minute Frosting from Betty Crocker
(which should not be called 7 minute frosting because it actually takes 9 1/2 minutes! just wanted to point that out ;0)
2 egg whites
1-1/2 cups sugar
1/4 tsp cream of tartar or 1 tbsp light corn syrup
1/3 cup cold water
1 tsp vanilla
Combine egg whites, sugar, cream of tartar and water in top of double boiler. Beat on high speed 30 seconds with electric mixer. Place over boiling water (water should not touch bottom of pan); beat on high speed 7 minutes. Remove pan from boiling water; add vanilla. Beat 2 minutes longer on high speed. Fills and frosts two 8- or 9-inch layers or frosts a 13x9-inch cake.
Frost cupcakes and sprinkle with coconut.
* I also added a small splash of coconut flavoring to the icing along with the vanilla. These were served at a board meeting and were a big hit. They were quick and easy to make and transported very well.
