Got bored and watched episodes about the Duggar family, and they made something called banana cake that is similar.
banana cake mix
box instant vanilla pudding
whipped topping, thawed
1Prepare the cake mix according to box directions in a 13x9 inch pan. Once done, poke holes all over the top of it with a chopstick.
2Prepare pudding mix and pour pudding over the top.
3Cover the pudding with the banana slices.
4Cover with a layer of whipped topping. How ever much or little you want, I maybe used two cups.
