Why I Love This Recipe

What’s not to love about a recipe that’s:

  • Naturally sweetened with banana and honey or maple syrup
  • Made with oat flour for a hearty, whole-grain base
  • Rich in protein and healthy fats thanks to peanut butter
  • Freezer-friendly and meal-prep approved!

It’s a muffin you can feel good about sharing with your kids and sneaking for yourself.


Ingredients

  • 2 ripe bananas, mashed
  • 1/2 cup peanut butter (creamy or crunchy)
  • 1/4 cup honey or maple syrup
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon cinnamon
  • 1 teaspoon baking soda
  • 1 1/2 cups oat flour (or blended rolled oats)
  • 1/2 cup milk (dairy or non-dairy)

Ingredient Swaps & Notes

  • Nut-Free? Use sunflower seed butter or almond butter instead.
  • Egg-Free? Substitute with two flax eggs (2 tbsp flaxseed + 6 tbsp water).
  • Gluten-Free? These are naturally gluten-free if you use certified gluten-free oats.
  • Add-ins? Chocolate chips, chopped nuts, or dried cranberries are all welcome!

How to Make Peanut Butter Banana Muffins

  1. Preheat & Prep
    Preheat your oven to 350°F (175°C). Line a muffin tin with paper liners or lightly grease each cup.
  2. Mix Wet Ingredients
    In a large bowl, mash bananas. Add peanut butter, honey (or maple syrup), eggs, and vanilla. Stir until smooth.
  3. Add Dry Ingredients
    In a separate bowl, whisk oat flour, baking soda, and cinnamon. Gently fold the dry mix into the wet until just combined.
  4. Add Milk
    Stir in the milk until the batter is evenly mixed and pourable.
  5. Fill the Muffin Tin
    Spoon batter into the muffin cups, filling each about 2/3 full.
  6. Bake
    Bake for 18–20 minutes, or until a toothpick inserted in the center comes out clean.
  7. Cool & Enjoy
    Let cool for 5 minutes in the pan, then transfer to a wire rack to cool completely.

Tips for Success

  • Use super ripe bananas with lots of brown spots for the best flavor and sweetness.
  • Don’t overmix the batter—just stir until the ingredients are incorporated.
  • If using chocolate chips, toss them in a little oat flour first to prevent sinking.

Serving Suggestions & Pairings

Enjoy these muffins with:

  • A smear of almond butter or more peanut butter
  • A drizzle of honey or maple syrup
  • A hot cup of coffee or this Refreshing Strawberry Mojito if you’re feeling fancy

Storage & Freezing Tips

  • Room Temp: Store in an airtight container for up to 3 days.
  • Fridge: Lasts up to a week in the fridge—just warm slightly before eating.
  • Freezer: Freeze in a single layer, then transfer to a zip bag. Reheat in microwave or toaster oven.
