Jello Cake......I just made this tonight for our dessert for Father's Day:
1 box white cake mix - follow package directions and bake accordingly. Cool 15 minutes.
Prepare jello (any flavor, I like lime a lot, but tonight I made it with orange jello) according to package. After dissolving the jello in boiling water, add one cup cold water. Poke holes in cake (I use a plastic toothpick or a shish-ka-bob skewer) every 1/2 inch so that there are holes all over the cake. Pour jello over cake. (the cake will immediately soak up all the jello). Put cake in fridge for 3-4 hours, then top with cool whip.
This is great for summer as it's served cold and can be garnished with fruit.
