Chocolate Peanut Butter Cake is a light, delicious cake that is not too sweet. You don't need frosting, just a scoop of vanilla ice cream or whipped cream.
Preheat oven to 350°F. Spray a 9"x13" baking dish.
Add the marshmallows to the baking dish, spread out evenly.
In a large mixing bowl, add the cake mix, water, peanut butter, oil, and the eggs. Beat on low speed using a hand mixer for about 1 minute. Then beat on medium speed for 2 minutes.
Pour the batter over the marshmallows. Spread evenly with a spatula.
Sprinkle the chocolate chips over the batter and bake for 25-30 minutes, or until a toothpick inserted into the center of the cake comes out clean.
Cool on a wire rack. Serve with dollops of vanilla ice cream, whipped cream, or plain.
Notes
*The marshmallows won't be visible when cake is baked. They add a touch of sweetness and help make the cake light and fluffy.
