"A moist, yummy cake that tastes just like banana pudding! Add some sliced bananas, dipped in lemon juice to prevent browning, layered on top of the whipped topping. Great for potlucks."
1Preheat oven to 350 degrees F (175 degrees C). Grease and flour a 9x13-inch baking dish.
2Whisk cake mix, water, vegetable oil, and eggs together in a bowl until smooth; pour into the prepared baking dish.
3Bake in the preheated oven until a toothpick inserted in the center of the cake comes out clean, 23 to 28 minutes.
4Whisk cold milk and pudding mix together in a bowl until pudding is soft and thickened, about 2 minutes.
5Poke holes into the cake using the handle of a clean wooden spoon. Pour pudding over cake, spreading evenly. Spread whipped topping over pudding layer and sprinkle vanilla wafers over whipped topping.
