Chocolate Peanut Butter Banana Frosting

When I developed the recipe, I worried that the banana might throw off the frosting texture. But, it didn’t take too much banana to impart enough banana flavor and the texture was spot on. It’s perfectly pipeable!

Tips for Making Banana Frosting

To make the best banana frosting:

  • Always use very ripe (almost black) bananas. For an even more intense banana flavor, try using caramelized bananas!
  • Make sure to mash the bananas really well – you don’t want banana clumps in the frosting.

For this chocolate banana frosting with peanut butter, make sure to use smooth peanut butter. As with my classic peanut butter frosting, using chunky peanut butter will make for a weird frosting texture.

Best Desserts to Pair with Banana Frosting

This chocolate peanut butter banana frosting pairs well with a vanilla cupcake recipe or a chocolate cupcake recipe. But, it would also be great on banana cupcakes, a banana cake, or my strawberry banana bread!

If you like the idea of a banana frosting, but don’t want the chocolate or peanut butter, start with my vanilla frosting and mix in two tablespoons of mashed bananas. It works really well!
