Peanut butter and mashed banana combined into moist chocolate muffins stuffed full of chocolate chips. If that doesn’t sound like perfection, I don’t know what does.

Ingredients you’ll need

Here’s a list of ingredients you’ll need to make these muffins. You can find my recipe card at the bottom of this post for the complete list with their amounts.

  • Plain/all-purpose flour
  • Cocoa powder: I used Hershey’s Natural Unsweetened Cocoa Powder.
  • Baking powder
  • Salt
  • Large eggs: You’ll need 2.
  • Caster/granulated sugar
  • Buttermilk: See my recipe notes below on how to make your own buttermilk.
  • Vegetable oil
  • Vanilla extract
  • Bananas: You’ll need 2 medium bananas, mashed.
  • Smooth peanut butter: Microwaved until runny – about 20 – 30 seconds.
  • Chocolate chips: You can use milk, dark, or semi-sweet.

How to make Chocolate Peanut Butter Banana Muffins

To make these muffins, simply grab a medium bowl and whisk together the flour, cocoa powder, baking powder, and salt. Set aside.

In a separate large bowl, whisk together the eggs and sugar until thick and lighter in colour.

Add the buttermilk, vegetable oil, vanilla, mashed banana, and peanut butter, and whisk until combined.

Add the dry ingredients in thirds and fold in until just combined – do not overmix. Fold in the chocolate chips.

The mixture will be thick and somewhat lumpy.

Spoon the mixture into a muffin pan lined with muffin cases (filling to the tops).

OPTIONAL: For the peanut butter swirl, spoon a small dollop of runny peanut butter on the tops, and use a knife or toothpick to create swirls.

Bake for 15 – 20 minutes, or until a toothpick inserted into the centre comes out clean.

Allow to cool for 5 – 10 minutes in the pan before transferring them to a wire rack to cool completely.

The printable recipe card with the FULL list of ingredients and instructions can be found at the bottom of this post.

NOTE: For best results, I highly recommend using the gram measurements (with a digital scale), rather than the cup measurements.

Cup measurements are simply not accurate enough, and I cannot guarantee the best results if you use them.

These muffins are amazing! I would definitely recommend! I didn’t use all of the two bananas as I found it made them a bit too sweet but altogether I think that they were great! I will definitely make these again. I put peanut butter in the middle of the muffins and found that it works quite well, definitely use runny peanut Butter though. Enjoy!

These baked up beautifully, I found them to be a little dry. I’ll add a third banana if I make these again.
