This easy Banana Pudding Cake-Mix Cake with marshmallow cream frosting tastes like banana pudding. With a few extra ingredients added to the mix, you get bakery-style results.




  • 1  15.25-ounce box yellow cake mix
  • 1  3.4-ounce box banana cream instant pudding mix
  • 1 cup water
  • 2/3 cup mayonnaise
  • 3 whole eggs


  • 3 bananas
  • 1 tablespoon granulated sugar


  • 1 box Betty Crocker Home Style Fluffy White Frosting Mix
  • 1/2 cup boiling water


  • 1 cup crushed vanilla wafers



  1. Preheat oven to 350°, prepare a 9×13 cake pan with spray oil and flour.
  2. Combine the cake mix, pudding mix, mayonnaise, and water into a large bowl; mix together, adding 1 egg at a time.
  3. Beat for 2 minutes.
  4. Pour batter into the cake pan and bake for 30 minutes or until a toothpick inserted into the middle of the cake comes out clean.
  5. Allow cake to thoroughly cool before spreading on the filling and frosting.


  1. Peel bananas and mash them with a fork in a medium-sized bowl.
  2. Mix in sugar.
  3. Spread filling over cooled cake.


  1. Empty the mix into a large bowl, pour boiling water into the bowl and mix on high to get stiff peaks formed; that will take 5-7 minutes while scraping the bowl every couple of minutes.
  2. Spread frosting over the filling, covering the cake completely.


Sprinkle cake with crushed vanilla wafers and refrigerate for at least 2 hours.


  • Store cake covered in the refrigerator.
  • Slice the cake in half to make a two-layer cake, spread filling on one half, and top with the other layer before frosting.
  • The ingredients of mayonnaise and vanilla pudding enhance the cake’s texture and moistness.
  • Use this cake mix recipe with other cake mix flavors substituting instant vanilla pudding for the banana cream pudding.
