For the cake

  • 1 box of your favorite yellow cake mix
  • 2 small boxes of instant banana pudding
  • 1/2 cup of veggie oil
  • 1 1/4 cups water
  • 4 eggs
  • 2 bananas mashed
  • 3/4 cups peanut butter

For the Icing:

  • 3/4 cups low-fat peanut butter
  • 3 cups powdered sugar
  • 1 stick of butter softened
  • 3-5 tablespoons skim milk more for a thinner icing, less for a thicker icing
  • mini chocolate chips


For the Cake:

  • Preheat oven to 350 F
  • Grease or spray a large bundt cake pan (I love the new olive oil cooking spray)
  • Combine cake mix, puddings, oil, water and eggs and mix in an electric mixer. Add in the peanut butter and mashed bananas and mix until smooth.
  • Pour batter into cake pan and bake 40-45 minutes or until toothpick inserted comes out clean.
  • Once the cake has cooled for at least 10 minutes, flip it over and place on a platter or plate. Allow to cool completely before adding icing.

For the Icing:

  • combine powdered sugar, softened butter, and milk with an electric mixer. Add the peanut butter and mix until fluffy and smooth.
  • Once the cake is completely cooled, ice liberally with the icing. The more the better :)
  • sprinkle with mini chocolate chips
  • Enjoy!
