Peanut Crunch Cake

"Here's a recipe that dresses up a plain old box cake mix," says Sue Smith of Norwalk, Connecticut. "Peanut butter and chocolate chips add fun, yummy flavor to this yellow cake."
  • Total Time
    Prep: 10 min. Bake: 40 min.
  • Makes
    16 servings


  • 1 package yellow cake mix (regular size)
  • 1 cup peanut butter
  • 1/2 cup packed brown sugar
  • 1 cup water
  • 3 eggs
  • 1/4 cup canola oil
  • 1/2 to 3/4 cup semisweet chocolate chips, divided
  • 1/2 to 3/4 cup peanut butter chips, divided
  • 1/2 cup chopped peanuts


  • In a large bowl, beat the cake mix, peanut butter and brown sugar on low speed until crumbly. Set aside 1/2 cup. Add the water, eggs and oil to remaining crumb mixture; blend on low until moistened. Beat on high for 2 minutes. Stir in 1/4 cup each chocolate and peanut butter chips.
  • Pour into a greased 13x9-in. baking pan. Combine the peanuts, reserved crumb mixture and remaining chips; sprinkle over batter.

    Delicious and easy. Doesn't taste like a mix. My adult children ask for it for their birthdays every year.

    Chocolate and peanut butter: great combination. I love that it makes its own topping without frosting

    I do not use boxed cake mixes often, but thought I would give this recipe a try anyway. I am glad I tried because my husband especially enjoyed it. He said it did not taste like a boxed cake mix. I plan to make it for our Memorial Day cook-out.

    I make this cake every time I have dinner guests and it always the biggest hit of the meal!!! Everyone thinks I make it from scratch because it tastes like nothing like any cake they have ever had. It's so easy and so tasty!

    Everyone likes the recipe. It's a nice change from traditional cake and frosting.

    This cake is easy to make and has a great peanut butter taste. However, I suggest using a binding agent like maybe butter to hold together chips on top. They immediately fall off when slicing and eating just making a mess.
