These healthy peanut butter banana muffins were a delicious result of my Sunday baking session and my need to use up extra-ripe bananas sitting on my counter. I tossed everything into a bowl, and luckily, they turned out incredibly moist and flavorful!

Not only do these muffins taste amazing, but they’re also a nutritious snack option. They’re dairy-free, gluten-free, and packed with protein, making them perfect for those with dietary restrictions. Once you bake these soft and fluffy muffins, they’re bound to become a household favorite.
Ingredients for Peanut Butter Banana Muffins
These muffins are made with wholesome ingredients and provide 6g of protein per serving. You probably already have everything you need in your pantry:
- Bananas: Use ripe bananas with brown spots for natural sweetness.
- Peanut butter: Opt for a natural, drippy peanut butter (just peanuts + salt). Either creamy or crunchy works!
- Eggs: Two eggs help bind the batter together.
- Sweetener: A touch of pure maple syrup for natural sweetness.
- Vanilla extract: Enhances the flavor.
- Milk: A splash of dairy-free milk (such as almond milk) keeps the muffins moist.
- Flour: Gluten-free oat flour keeps these muffins light and nutritious.
- Baking essentials: Baking powder, salt, and cinnamon add structure and flavor.
- Mix-ins: Mini chocolate chips make these muffins extra delicious. Use dairy-free chocolate chips for a completely dairy-free option.
How to Make Your Own Oat Flour
Making oat flour is easy! Simply blend gluten-free rolled or old-fashioned oats in a blender until they reach a fine, flour-like consistency. You’ll need about 1 1/2 cups of oats to make 1 cup of oat flour.
Can I Use a Different Flour?
For the best results, stick with oat flour. However, chickpea flour might work as a substitute.
Step-by-Step Instructions
- Preheat & Prep: Preheat your oven to 350°F and line a 12-cup muffin tin with liners. Lightly spray the liners with nonstick spray.
- Mix Wet Ingredients: In a large bowl, mash the bananas and mix in peanut butter, eggs, maple syrup, vanilla, and milk until smooth.
- Add Dry Ingredients: Stir in the oat flour, baking powder, cinnamon, and salt. Fold in the chocolate chips.
- Bake: Evenly divide the batter into the muffin liners. Bake for 20-25 minutes until a toothpick inserted comes out clean.
- Cool & Enjoy: Let the muffins cool on a wire rack before serving.
Tips for Perfect Muffins
- Peanut-Free Option: Swap peanut butter for almond or cashew butter.
- Muffin Liners: Spray the inside of the liners with nonstick spray to prevent sticking.
- Dairy-Free Chocolate Chips: Use dairy-free chocolate chips to keep this recipe dairy-free.
- Vegan Option: You can try substituting the eggs with flax eggs.
How to Store & Freeze
- To Store: Keep muffins in an airtight container at room temperature for one day, then transfer them to the fridge.
- To Freeze: Let muffins cool completely, place them in an airtight container, and freeze for up to three months. Thaw at room temperature or microwave in 30-second intervals.
