My Kids Keep Asking Me To Make This… Now You Know Why. A delicious cake that tastes exactly like a peanut butter and jelly sandwich, with the cake and peanut butter giving it a bread-like flavor.
Preheat oven to 350º. In a large mixing bowl, add cake mix and peanut butter, mixing until crumbly. Mix in milk and eggs until completely incorporated; the batter will be chunky. Pour into a lightly greased 9x13 cake pan and bake for 30-40 minutes or until a toothpick comes out clean. Let cool on the counter for 15 minutes. Using a rounded kitchen utensil, poke holes across the top of the cake. In a microwave-safe bowl, add 1 cup of jelly and microwave in 30-second intervals until runny; pour evenly over the top of the cake. Place cake in the fridge for 2 hours to cool completely. Once chilled, spread on whipped topping. Microwave the remaining jelly and peanut butter to pour over (optional: mix peanut butter with whip topping before spreading). Garnish with chopped peanuts if desired and serve.
