These Banana Oat Flour Muffins are soft, fluffy, and full of natural banana flavor. Made with wholesome oat flour and a touch of warm cinnamon, they’re an easy one-bowl breakfast or snack the whole family will enjoy.

I love baking muffins because they’re convenient for breakfast, packed lunches, snacks, or whenever a little baked comfort is needed. These Banana Oat Flour Muffins are a favorite way to use up very ripe bananas. The muffins are tender and moist, with a pleasant nutty note from the oat flour and the cozy flavor of cinnamon.
Unlike some oat flour recipes that can turn out dense or crumbly, this recipe yields light, springy muffins with a soft crumb. They come together in one bowl in about ten minutes of prep and bake in roughly 15–20 minutes, making them ideal for quick meal prep or last-minute baking.

How to make banana oat flour muffins
This is a straightforward one-bowl recipe that works well even for beginner bakers. A few quick steps and you’ll have a batch of tender banana oat muffins ready to enjoy.
Pro tip: The riper and more spotted your bananas, the more natural sweetness and banana flavor they contribute to the muffins.

- Preheat the oven to 400°F (200°C). Line a standard 12-cup muffin pan with paper liners or lightly grease the cups.
- In a large bowl, mash the ripe bananas with a fork until mostly smooth. Add the eggs, coconut sugar, oil, and almond milk and whisk until combined.
- Add the oat flour, baking powder, ground cinnamon, baking soda, and salt to the wet ingredients. Whisk until the batter is smooth and no dry lumps remain.
- Divide the batter evenly among the 12 muffin cups. Sprinkle walnut pieces on top of each muffin, or fold half of them into the batter before filling the pan.
- Bake on the middle rack for 15–20 minutes, or until the tops are golden and spring back lightly when pressed, or a toothpick inserted into the center comes out clean or with a few moist crumbs.
- Cool the muffins in the pan for about 10 minutes, then transfer them to a wire rack to cool completely.
Tips for success
- Use very ripe bananas with brown spots for the best flavor and sweetness.
- Measure oat flour by spooning it into the cup and leveling, rather than scooping directly from the container.
- Do not overbake — remove muffins when the centers just spring back or a toothpick shows a few moist crumbs.
- Allow muffins to cool briefly in the pan to set, then finish cooling on a wire rack to avoid sogginess.

Recipe variations
Customize these muffins to suit your taste or pantry:
- Swap walnuts for pecans, sliced almonds, or pumpkin seeds, or omit nuts for a nut-free version.
- Fold in 1/2 cup of chocolate chips or shredded coconut for added texture and flavor.
- Replace cinnamon with cardamom or a chai spice blend, or add 1 teaspoon of vanilla extract for a different aroma.
