This is one of those things that couldn't be easier to make, and everyone loves it. Well, everyone except my littlest fussbudget. He has to do something to prove he's a fussbudget, right?
1 cake: white, yellow or pound, preferably sheet form, but loaf will do
1 box of jello mix (3 ounce)
whipped cream (cream, vanilla extract, sugar)
You can make a white or yellow cake from mix or scratch, or a pound cake, or just buy one unfrosted at the store - it is, after all, summer, and therefore too hot for normal people to bake, right? If you bake it, let it cool. Pour 1 cup boiling water into a 4 cup measuring cup, sprinkle the jello over it, then stir with a wire whisk to dissolve and blend thoroughly. Add 2 cups of ice cubes, and stir with a slotted spoon until the jello starts to thicken and is partially set. Using the handle of a wooden spoon, poke holes in your cake mercilessly - lots of holes, with about 1" of cake around each hole. Pour the jello into the holes and over the top of the cake. Frost with the whipped cream, refrigerate for at least 30 minutes and serve.
You can take this to a 4th of July picnic. Use blue jello and red-colored whipped cream to be really festive looking, or be like me, and use whatever you have on hand. Either way, it won't last long!
