1 white or yellow cake mix
1 lg. pkg. Jello (your choice, but red looks best)
1 container Cool Whip

Mix and bake cake according to package directions. Cool. When cake has cooled, use dinner fork and poke holes all over cake going all the way to the bottom of pan. Make the holes about 1/4" apart. Mix Jello with 1/2 the amount of water specified on package. Slowly pour all liquid over cake trying to pour as much as possible into the fork holes. Refrigerate cake until Jello is set, about 2 to 3 hours. Spread Cool Whip over cake like frosting. Keep uneaten cake in refrigerator.
