Ingredient Highlights

With only four ingredients, each one plays an essential role in both structure and flavor.

Bananas

Ripe bananas provide natural sweetness, moisture, and binding power. As they bake, their sugars deepen, creating a rich banana flavor while replacing the need for eggs or oil. For best results, use bananas with brown spots on the peel.

Rolled Oats

Rolled oats are blended into oat flour, forming the base of the loaf. They provide structure, fiber, and a mild, nutty flavor. Oats are naturally gluten-free, but certified gluten-free oats should be used for those with sensitivities.

Ingredients

Core Ingredients

  • 3 large ripe bananas, mashed

  • 2 cups rolled oats, blended into flour

  • ¼ cup pure maple syrup or honey

  • 1 teaspoon baking soda

Optional Add-Ins and Substitutions

While delicious on its own, this recipe is easy to customize:

  • ½ teaspoon cinnamon or vanilla extract

  • ¼ cup chopped walnuts or pecans

  • ¼ cup dairy-free chocolate chips

  • Agave or date syrup instead of maple syrup

  • Quick oats (blended into flour) if needed

These additions enhance flavor without changing the base structure.

Instructions

  1. Preheat the oven to 350°F (175°C). Lightly grease a standard loaf pan or line it with parchment paper.

  2. In a large bowl, mash the bananas until mostly smooth.

  3. Stir in the maple syrup (or honey) until fully combined.

  4. Add the oat flour and baking soda. Mix gently until just incorporated. The batter will be thick.

  5. Transfer the batter to the prepared loaf pan and smooth the top evenly.

  6. Bake for 35–40 minutes, or until the top is lightly golden and a toothpick inserted into the center comes out clean.

  7. Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.

Cooling is essential for the loaf to set properly and slice cleanly.

Tips for Best Results

  • Use very ripe bananas for maximum sweetness and moisture

  • Blend oats thoroughly into a fine flour

  • Avoid overmixing to prevent a dense texture

  • Allow the loaf to cool fully before slicing

  • Line the pan with parchment paper for easy removal

  • Warm honey slightly before mixing if using

Flavor Variations

This simple base can be adapted in many ways:

  • Chocolate Banana Bread: Add cocoa powder and dairy-free chocolate chips

  • Nutty Banana Bread: Fold in chopped walnuts or pecans

  • Blueberry Banana Bread: Add fresh or frozen blueberries

  • Spiced Banana Bread: Add cinnamon, nutmeg, and cloves

  • Protein Banana Bread: Add plant-based protein powder and slightly reduce oat flour

Serving Suggestions

  • Enjoy warm with almond or peanut butter

  • Toast slices for a crisp exterior and soft center

  • Serve with fruit and yogurt for breakfast

  • Pair with tea or coffee for a light snack

  • Top with dairy-free ice cream or coconut cream for dessert

Freezer

Slice and freeze for up to 2 months. Thaw overnight or reheat directly from frozen.

Reheating

Why Oat Flour Works in This Recipe

Oat flour absorbs moisture efficiently, helping the loaf stay soft and tender for days. It provides fiber, supports steady energy, and creates a crumb similar to traditional flour without gluten. Its mild flavor allows the banana and maple syrup to shine, making it ideal for wholesome baking.

Frequently Asked Questions

Can I use store-bought oat flour?
Yes. Use 2 cups oat flour at a 1:1 ratio.

Is this recipe vegan?
Yes, when using maple syrup instead of honey.

Do I need a blender?
You’ll need a way to grind oats into flour. A blender, food processor, or coffee grinder works well.

Why didn’t my bread rise?
Ensure your baking soda is fresh, mix gently, and bake in a fully preheated oven.
