Ingredients

  • 2 bananas about 1 cup mashed
  • 1 cup rolled oats or oat flour
  • 1 teaspoon baking powder

Instructions

  • Preheat the oven to 350°F (175°C) and line a muffin tin with liners or lightly grease it.
  • Prepare the oat flour by blending 1 cup of rolled oats in a blender or food processor until it reaches a fine flour-like consistency.
  • Mash the bananas in a medium bowl until smooth.
  • Mix the batter by stirring in the oat flour and baking powder until well combined.
  • Let the batter rest for 5 minutes to allow the baking powder to activate.
  • Fill the muffin tin about ¾ full with the batter.
  • Bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean.
  • Cool for a few minutes, then enjoy!

  • Extra Sweetness: Add 1-2 tablespoons of maple syrup or honey if you prefer sweeter muffins.
  • Flavor Boost: Mix in cinnamon or vanilla extract for extra depth.
