I bake muffins often because they’re handy for breakfasts, lunch boxes and quick snacks.

Why you’ll love this recipe
- Light, fluffy muffins with real banana flavor and a hint of cinnamon.

Recipe ingredients
These muffins use a short list of everyday, wholesome ingredients. Most quantities are included in the recipe card below:
- Bananas: Use very ripe, spotted bananas for maximum sweetness and flavor.
- Oat flour: A whole‑grain, naturally gluten‑free alternative to all‑purpose flour. It gives these muffins a tender texture. You can make oat flour at home by processing rolled oats until finely ground.
- Eggs: Provide structure and help the muffins rise.
- Coconut sugar: A mildly caramelized, unrefined sweetener. You can swap granulated or brown sugar if preferred.
- Oil: Neutral oils like vegetable, light olive or coconut oil work well; choose your favorite.
- Milk: Any dairy or non‑dairy milk is fine; the recipe uses almond milk as written.
- Baking powder and baking soda: Both help the muffins rise and stay light.
- Cinnamon: Optional but recommended for warm, cozy flavor.
- Walnuts: Used here as a topping for toasty crunch; swap for pecans, almonds, seeds or omit.

How to make banana oat flour muffins
The method is straightforward and requires only one bowl. Mash ripe bananas, whisk in the wet ingredients, fold in dry ingredients, portion into muffin cups and bake. The total active time is low and the cleanup is easy.
Pro tip: The riper the bananas, the more natural sweetness and banana flavor they contribute to the muffins.

- Preheat the oven to 400°F (200°C) and line a standard 12‑cup muffin pan with paper liners.
- In a large bowl, mash the bananas with a fork. Add the eggs, coconut sugar, oil and milk, then whisk until combined.
- Add the oat flour, baking powder, baking soda, cinnamon (if using) and salt. Stir until the batter is smooth and no large lumps remain.
- Divide the batter evenly among 12 muffin cups and sprinkle walnut pieces on top.
- Bake 15–20 minutes on the middle rack, or until the tops are golden and spring back lightly or a toothpick comes out clean.
- Cool the muffins in the pan for 10 minutes, then transfer to a wire rack to cool completely.
Tips for success
- Choose very ripe bananas with many brown spots for the best flavor and sweetness.
- Measure oat flour by spooning it into a cup and leveling to avoid dense muffins.
- Do not overbake—remove muffins when a toothpick shows a few moist crumbs for the most tender texture.
- Allow muffins to cool slightly in the pan before removing so they hold their shape.

Recipe variations
Customize these muffins to suit your preferences or what’s in your pantry:
- Fold 1/2 cup chocolate chips into the batter for chocolatey banana muffins.
- Stir 1/2 cup chopped nuts into the batter or simply sprinkle them on top for banana‑nut muffins.
- Try different spices—cardamom, chai spice or a splash of vanilla extract work well in place of cinnamon.
- Top with rolled oats, seeds or a sprinkle of coarse sugar for added texture and visual appeal.
