Rainbow Layer Cake

Directions

1. Preheat oven to 350°. Line bottoms of three greased 9-in. round baking pans with parchment; grease paper.
2. Prepare cake mix batter according to package directions, substituting three whole eggs for egg whites. Divide evenly among three bowls. Stir one flavor of gelatin into each bowl until blended. Pour each into a prepared pan. Bake 20-25 minutes or until a toothpick inserted in center comes out clean.
3. Cool in pans 10 minutes before removing to wire racks; remove paper. Cool completely. Spread frosting between layers and over top and sides of cake.
4. Freeze option: Wrap cooled cake layers in plastic wrap, then cover securely in foil; freeze. To use, thaw cakes before unwrapping. Assemble as directed.
