Instructions

  • Preheat oven to 350°F (180°C) and line a 12-count muffin tin with muffin liners.
  • In a bowl, combine flour, baking powder, baking soda, salt, and cinnamon. Set aside.
  • In the bowl of a stand mixer fitted with the paddle attachment combine butter and sugars. Beat at medium-high speed for about 4 minutes until pale and fluffy.
  • Add the egg and vanilla extract, whisk until combined. Stir in the mashed bananas.
  • Add the dry ingredients to the wet mixture and stir just until combined. Don't overmix!
  • In a small bowl combine peanut butter and powdered sugar. Mix until smooth.
  • Spoon about 1 heaping tablespoon of batter into each muffin cup. Place on heaping tsp of filling on top. Divide remaining batter between the muffin cups.
  • In a small pan over medium heat melt the butter. Then add chopped peanuts and maple syrup. Stir for about 1 minute then remove from heat. Top each muffin with a tsp of the topping.
  • Bake muffins for about 20-25 minutes or until a skewer inserted into the center comes out clean with only a few crumbs attached. Let the muffin cool down for about 10 minutes in the pan then transfer them to a cooling rack.
