1 cake mix prepared according to box instructions
1 small box lime jello (you can use any flavor)
Mix 3 tbsp of dry lime jello into cake batter. Bake the cake according to box instructions.
1 1/2 cups sugar
1/3 cup cold water
2 egg whites
1/4 tsp cream of tartar
1 tsp vanilla
In the top of a double boiler combine sugar, cold water, egg whites, and cream of tartar. Add remaining dry lime jello. Beat with an electric mixer on low speed for 30 seconds. Place over boiling water (upper pan should not touch water). Cook, beating constantly with the electric mixer on high speed, about 7 minutes or till frosting forms stiff peaks. Remove from the heat; add vanilla. Beat 2 to 3 minutes more or till it reaches spreading consistency. This frosts the tops and sides of two 8 or 9 inch cake layers or one 10 inch tube cake.
