Moist Oat Flour Banana Bread Recipe

This Oat Flour Banana Bread blends ripe mashed bananas, oat flour, and rolled oats into a moist, naturally sweet loaf that’s completely gluten-free. The crumb is tender yet satisfying thanks to the oat flour, and the optional streusel topping adds a crunchy, buttery contrast. It’s an inclusive recipe that works well for gatherings, weekday breakfasts, or a comforting afternoon treat.

Although I’m not strictly gluten-free, I often make this oat flour version when I know guests might prefer or need gluten-free options. The texture and flavor are very similar to classic banana bread, and the oat flour plus rolled oats give it a pleasant heartiness. Top with the streusel for extra texture — it transforms the loaf into something truly special.

Top Tips from the Fit Foodie Kitchen

• Aim for a pourable batter. If your batter seems too thick, add 1 tablespoon of unsweetened almond milk at a time until it pours easily but still has body.
• Oven temperatures and pans vary. During testing, bake times ranged from 40 to 55 minutes depending on the oven. Use the toothpick test: insert a toothpick near the center and look for moist crumbs but no wet batter.
• Let the loaf cool completely on a wire rack before slicing. Cooling stabilizes the crumb and prevents the loaf from falling apart.

Can I make this recipe vegan?

This specific recipe hasn’t been tested with vegan egg substitutes here, but many bakers successfully swap eggs for a flax egg or other vegan egg replacers. If you want a tested vegan option instead of adapting this recipe, try a dedicated vegan banana bread recipe that uses plant-based substitutes and has the texture optimized for that swap.

What if I don’t have a loaf pan?

No loaf pan? Turn the batter into muffins. Bake times will be shorter—check after 15–20 minutes depending on muffin size. The same batter and topping work well for individually portioned muffins that are ideal for grab-and-go breakfasts.

How to Store and Freeze

Store this banana bread in an airtight container at room temperature for up to 3 days. For longer storage, wrap the cooled loaf tightly and freeze for up to 3 months. Thaw in the refrigerator or at room temperature before slicing.

Prep: 20 mins • Cook: 40 mins • Total: 1 hr • Servings: 8

Ingredients

Streusel Topping

• 2 tablespoons oat flour
• 1/3 cup rolled oats
• 2 tablespoons packed light brown sugar
• 1 1/2 tablespoons coconut oil

Dry Ingredients

• 2 cups oat flour
• 1/2 teaspoon baking soda
• 2 teaspoons baking powder
• 1/2 teaspoon kosher salt

Wet Ingredients

• 1/2 cup packed light brown sugar
• 1/4 cup coconut oil
• 2 teaspoons vanilla extract
• 3 medium ripe bananas, mashed (about 1 cup)
• 2 large eggs
• 1/2 cup plain 2% Greek yogurt
• 1/4 cup unsweetened almond milk

Instructions

1. Preheat the oven to 350°F (175°C) and line a standard loaf pan with parchment paper.
2. Prepare the streusel first: combine oat flour, rolled oats, brown sugar, and coconut oil in a bowl. Cut or rub the ingredients together with a fork or your fingers until a coarse crumble forms. Set aside.
3. In a medium bowl, whisk the dry ingredients: oat flour, baking soda, baking powder, and salt. Set aside.
4. In a separate large bowl, whisk together the wet ingredients: brown sugar, coconut oil, vanilla, mashed bananas, eggs, Greek yogurt, and almond milk until smooth.
5. Gradually add the dry ingredients to the wet ingredients, mixing until combined. The batter should be pourable but thick; if it’s too dense, stir in 1 tablespoon of almond milk at a time until it loosens slightly.
6. Pour the batter into the prepared loaf pan, smoothing the top gently. Sprinkle the streusel evenly over the batter.
7. Bake for 30 minutes, then loosely tent the pan with foil and bake for an additional 20 minutes, or until a toothpick inserted into the center comes out with moist crumbs but no raw batter. Total bake time may vary by oven; check from 40 to 55 minutes.
8. Remove from the oven and let rest for 10 minutes in the pan. Transfer the loaf to a wire rack to cool completely before slicing. Slicing too early can make the loaf crumbly.

Tips & Notes

• The batter should be pourable; add almond milk by tablespoonfuls if needed to reach the right consistency.
• Because every oven bakes differently, monitor your loaf after 40 minutes and use the toothpick test for doneness.
• For muffins, reduce baking time and check after 15–20 minutes. For a vegan loaf, experiment with a flax egg substitute and slightly more moisture to compensate.
