Christmas Layer Cake

Christmas will soon be here, and I was feeling quite festive and inspired the other day. So I made a Christmas themed cake. The red and green colors showing through the cake and the red and green sprinkles give a very festive appearance. The trick to get the red and green in the cake is actually quite simple, the same technique I used at Halloween (see {Orange Poke Cake}). This also makes the cake extra moist! 

Christmas Layer Cake
2 round white cake layers, baked (cooled, optional)
1 package green instant gelatin mix (lime)
1 package red instant gelatin mix (cherry, raspberry, or strawberry)
2 cups boiling water
2 packages instant whipped topping (or use real whipped cream)
1 cup cold milk
1 Tablespoon vanilla extract
Christmas sprinkles

The cakes need not be cool, but should be removed from pans and placed on plates. Pierce the cakes all over with a fork.
In small bowls, dissolve each of the gelatins in one cup of boiling water. Whisk until dissolved. Carefully pour one over each cake. Cool.
A few hours later, whip the topping mix with the milk and vanilla. Spread half of this one one of the cakes. Top with other cake. Spread top with remaining topping. Garnish with sprinkles. 

You may use a boxed mix, purchased cakes, or your own homemade cakes for this recipe, however white cake must be used in order for the colors to show through. You could decorate the cake with any type of frosting instead of cream or whipped topping, but I like the texture and light, fluffy appearance of the topping, almost like snow.
