Add to Collection


  • 1/2 cup butter softened
  • 1 cup white sugar
  • 2 large eggs
  • 1 cup mashed really ripe bananas
  • 2/3 cup peanut butter*
  • 1 Tbsp. milk
  • 1 tsp. vanilla extract
  • 2 cups all-purpose flour
  • 1 tsp. baking soda
  • 1/2 tsp. salt
  • 3/4 cup chocolate chunks**
  • 1 Tbsp. white sugar for sprinkling before baking.


  • Line 10 muffin cups with paper liners and set aside. Preheat oven to 350° F.
  • In a large bowl with an electric mixer or the bowl of a stand mixer fitted with a paddle attachment, cream butter and 1 cup sugar until light and fluffy. Add eggs, one at a time, beating well after each addition. Beat in the bananas, peanut butter, milk and vanilla.
  • In a separate medium bowl, whisk together the flour, baking soda and salt. Add to creamed mixture just until moistened. Fold in the chocolate chunks.
  • Divide batter between the 10 prepared muffin cups. Sprinkle with remaining white sugar. Fill any empty muffin cups 1/2 full with water.
  • Bake at 350° for 30-35 minutes or until a toothpick inserted in the centre of the muffins comes out clean. Cool for 5 minutes before removing from pans to finish cooling on wire racks.


* I used regular pantry peanut butter for my muffins (Skippy, to be exact :) I haven’t tested these with natural peanut butter, though I suspect it would work just fine. Let me know if you try it! As for the bananas, the more ripe they are, the better the flavour!
** While you could use regular chocolate chips in these muffins, I highly recommend picking up some chocolate chunks. The generous pieces of chocolate are a big part of the appeal of these muffins (together with the banana and peanut butter).
