Jell-O Cake! And, oh! So easy to make! Bake a white cake according to package directions. While cake is still warm from the oven, and using the round end of a wooden spoon, poke holes, spacing them about an inch apart, all over the top of the cake. After cake is completely cool, mix one cup of hot water with whatever flavor of Jell-O brand gelatin you prefer (we like blueberry or strawberry). When gelatin is completely dissolved, add one cup cold water, and stir thoroughly. Ladle gelatin mixture over top of cake, making sure a little goes down into every hole. Top cake with one envelope of Dream Whip whipped topping mix, made according to package directions. Refrigerate cake until ready to serve.
