Banana Chocolate Chip Cake with Peanut Butter Frosting is a delicious and moist cake loaded with ripe bananas, mini chocolate chips and topped with the easiest 3 ingredient peanut butter frosting.

Have you ever accidentally ordered 8 bunchs of bananas instead of 8 single bananas on an online grocery order? No? Just me? I had to put some of these bananas to good use after my online order mishap and needless to say, the kids were pumped about it and the cake was gone in less than 24 hours.

If you love a peanut butter, chocolate and banana combo, well you just found your new favourite recipe! This is one of those cakes that you can barley wait for it to cool down to enjoy. I’ve made this recipe a few times with and without the frosting, and while we love an indulgent frosting, it still tastes great without it. It’s basically just a big banana bread so it works really well as a quick breakfast, afternoon snack, or something on the sweeter side after dinner.

Here is a quick overview of the ingredients you’ll need to make my Banana Chocolate Chip Cake with Peanut Butter Frosting. For the exact detailed measurements and ingredients, scroll to the bottom of this page to review my recipe card.

  • bananas
  • butter
  • sugar
  • all purpose flour
  • eggs
  • vanilla extract
  • mini chocolate chips
  • peanut butter
  • icing sugar
  • milk
  • baking soda
  • salt
  • cinnamon
  • nutmeg

Tips before getting started

  • Be sure the butter is melted before getting started. This will ensure it mixes well into the bananas, avoiding it from becoming clumpy.
  • Use very ripe bananas! The mushier, the better! You can tell if a banana is very ripe by the colour of its peel. If the peel is very dark in colour, and extremely soft to touch, it’s perfect!

Storing & freezing instructions

How to store banana cake? Once the cake has completed cooled, you can store it in a ziplock back or airtight container and it will keep fresh for up to 5 days. I leave mine on the counter, but you can also keep it in the fridge.

Is this recipe freezer friendly?
Yes! Just don’t freeze it with the peanut butter frosting. Wrap it with plastic wrap, and add it to a large ziplock bag and freeze for up to 3 months.

    I have been using the same amazing banana bread recipe for years (my husband LOVED the old recipe). I decided to try something new today, and my husband says this is his new favourite. I will be using this recipe from now on. This banana chocolate chip cake is SO good! The peanut butter icing is to die for.

    Thanks Sammy!
