Classic Oat Flour Banana Bread (Gluten-Free & Naturally Sweetened with Maple Syrup)

If you’ve been baking with oat flour lately, you’re going to love this recipe.

This Classic Oat Flour Banana Bread is soft, moist, lightly sweet, and tastes just like traditional banana bread — but it’s made completely gluten-free and naturally sweetened with pure maple syrup.

No refined sugar. No complicated flour blends. No chocolate chips. Just simple ingredients that create a tender loaf with that iconic golden crack down the center.

It’s the kind of banana bread you can make on a Sunday afternoon and enjoy all week long — for breakfast, snacks, or alongside coffee.

Once you try it, it may become your go-to gluten-free banana bread recipe.

Why Bake with Oat Flour?

Oat flour is one of the easiest gluten-free flours to work with. Unlike many gluten-free blends, it doesn’t require xanthan gum or multiple starches to create structure.

When paired with eggs, oat flour produces:

• A soft, tender crumb

• A fluffy but sturdy texture

• A slightly hearty, satisfying bite

• A mild flavor that doesn’t overpower the bananas

Even better — you can make your own oat flour at home in minutes by blending rolled oats.

If you need the recipe to be strictly gluten-free, just be sure your oats are labeled certified gluten-free.

Oat Flour Banana Bread Recipe Ingredients

Here’s what makes this loaf work so beautifully:

Oat Flour

Oat flour is simply finely ground oats. You can buy it pre-made or blend rolled oats in a high-speed blender until they reach a fine, flour-like consistency. While oats are naturally gluten-free, they are often processed in shared facilities, so look for certified gluten-free oats if necessary.

Ripe Bananas

This recipe tastes best when your bananas are very ripe — deeply speckled and soft. The riper they are, the sweeter and more flavorful your banana bread will be. Overripe bananas also add moisture, which is essential when baking with oat flour.

Eggs

Since oat flour doesn’t contain gluten, eggs provide the binding and lift that give banana bread its classic structure. They help the loaf rise properly and prevent it from becoming gummy in the center.

Olive Oil

Instead of butter or coconut oil, this recipe uses olive oil (or another neutral liquid oil). Liquid oils keep the bread tender even after refrigeration and help maintain a soft crumb.

Pure Maple Syrup

Maple syrup replaces granulated sugar in this recipe, adding natural sweetness and subtle caramel depth. Because it’s a liquid sweetener, it also contributes to the moist texture of the bread. Be sure to use 100% pure maple syrup.

Baking Powder

Baking powder gives this loaf its lift and helps create that beautiful crack along the top as it bakes.

Spices

Ground cinnamon, vanilla extract, and a pinch of salt enhance the banana flavor and balance the sweetness, making each slice warm and comforting.

How to Make Oat Flour Banana Bread

Step 1: Prepare Your Pan

Preheat your oven to 350°F (175°C).

Lightly grease a standard 9×5-inch loaf pan and line it with parchment paper for easy removal later.

Step 2: Mash the Bananas

In a large mixing bowl, mash your ripe bananas until mostly smooth. A few small lumps are perfectly fine — they add texture and pockets of banana flavor.

Step 3: Mix the Wet Ingredients

Add the eggs, olive oil, maple syrup, and vanilla extract to the mashed bananas.

Whisk until smooth and fully combined.

Step 4: Add the Dry Ingredients

Add the oat flour, baking powder, cinnamon, and salt to the bowl.

Stir gently until the batter looks uniform and no dry flour pockets remain. Avoid overmixing — just mix until combined.

The batter will be thick but scoopable.

Step 5: Bake

Pour the batter into the prepared loaf pan and smooth the top.

Bake for 45–55 minutes, or until:

• The center feels firm

• A toothpick inserted comes out clean

• A golden crack forms along the top

If the top begins browning too quickly, tent loosely with foil during the final 10 minutes.

Step 6: Cool Completely

Allow the loaf to cool in the pan for at least 30 minutes before transferring to a wire rack.

For clean slices, wait until the bread is fully cooled. Oat flour breads slice best once completely set.

Storage Tips
