This impressive-looking, no-bake, make-ahead dessert is guaranteed to be a hit with your guests at your next summer gathering. It also requires just four ingredients. You simply mix together whipped topping and bananas, then the remaining whipped topping with peanut butter, and crumble up some chocolate wafers. Spread the peanut butter cream in your pan, top with cookies, then alternate between the banana cream and peanut butter cream and cookies. It tastes better as it sits, so it's best to leave the cake in the fridge overnight. You'll love the convenience of having the cake ready to go when you're about to serve dessert.
