  • Total Time: 40 minutes
  • Yield: 12 muffins 1x
  • Diet: Vegetarian


  • 2 large or 3 small over ripe bananas, about 11 1/4 cups mashed
  • 3/4 cup (180 g) peanut butter
  • 1/2 cup (114 g, or 1 stick) unsalted butter
  • 3/4 cup (150 g) granulated sugar
  • 2 large eggs
  • 1 tsp. vanilla extract
  • 1 3/4 cup (245 g) all-purpose flour
  • 1 tsp. baking powder
  • 1/4 tsp. baking soda
  • 1 tsp. fine-grain salt
  • 1 cup (6 oz.) dark chocolate chips or chunks


  • Preheat the oven to 400° and grease a 12 cup muffin tin. Alternatively, you can line them with paper muffin liners.
  • To make peanut butter banana muffins, begin by peeling and mashing 2 large or 3 small bananas. You want to have 1 to 1 1/4 cups of mashed banana.
  • Stir the banana mash together with the 3/4 cup of peanut butter.
  • Add the butter and sugar and mix it into the peanut butter banana mixture until it’s well combined.
  • Stir in the eggs and vanilla extract until they are just combined.
  • In a small, separate bowl, combine the ??? cups of all-purpose flour, 2 tsp. baking powder, and 1 tsp. of salt. Stir them together to evenly distribute the ingredients.
  • Add the dry ingredients to the wet and use a wooden spoon or rubber spatula to stir them together until there are just a few streaks of flour visible.
  • Pour in 3/4 of the chocolate chips or chunks (if you’re using them) and continue stirring until they are evenly distributed and the flour is completely mixed in.
  • Divide the batter evenly between the 12 muffin cups.
  • Sprinkle a few of the remaining chocolate chunks on top.
  • Bake the muffins at 400° for 20-22 minutes, or until the tops are a deep golden brown and look slightly crusty.
  • Allow the peanut butter banana muffins to cool slightly before removing them from the tin. Slide a knife or fork down the side of each muffin and lift it out, rather than dumping them, to avoid having melted chocolate splattered everywhere.
