How to Make Flourless Cinnamon Swirl Banana Bread Recipe
Step 1: Prepare Your Oven and Pan
Preheat your oven to 350°F (175°C) and line a 9×5-inch loaf pan with parchment paper. This step ensures your bread bakes evenly and comes out cleanly, ready for that perfect presentation.
Step 2: Blend the Batter
In a blender or food processor, combine the mashed bananas, eggs, almond butter, honey (or maple syrup), vanilla extract, rolled oat flour, baking powder, baking soda, salt, and one teaspoon of cinnamon. Blend until the mixture is smooth and creamy—this harmonious blend is the heart of your bread, ensuring every bite is tender and rich.
Step 3: Start Layering the Batter
Pour half of the smooth batter into your prepared loaf pan, spreading it evenly so you have a solid base for the cinnamon swirl.
Step 4: Create the Cinnamon Swirl
Mix the remaining teaspoon of cinnamon with the brown sugar or coconut sugar. Sprinkle half of this fragrant cinnamon sugar mixture evenly over the batter in the pan. This step brings that gorgeous cinnamon swirl we all crave.
Step 5: Finish the Layers and Swirl
Add the remaining half of the batter on top of the cinnamon sugar layer, spreading gently. Then sprinkle the rest of the cinnamon sugar mixture over the top. Gently swirl the batter with a knife to create a beautiful cinnamon marbled effect that will tantalize your eyes and taste buds alike.
Step 6: Bake to Perfection
Bake your bread in the preheated oven for 40 to 45 minutes. You’ll know it’s perfectly baked when a toothpick inserted into the center comes out clean or with just a few moist crumbs clinging to it. The aroma filling your kitchen at this point will make it impossible to wait any longer.
Step 7: Cool and Serve
Let the bread cool for about 10 minutes in the pan before transferring it to a wire rack to cool completely. Cooling allows the bread to set perfectly so your slices hold together beautifully.

Absolutely! Using certified gluten-free oats ensures your Flourless Cinnamon Swirl Banana Bread Recipe is safe for gluten intolerance while keeping that great oat flavor and texture.

You can swap almond butter with peanut butter, sunflower seed butter, or even tahini, depending on your preference and dietary needs. Each will bring a unique flavor twist to the recipe.
How ripe should the bananas be?
For the best sweetness and moisture, use bananas that are very ripe with plenty of brown spots. They mash easily and give the bread its natural sweetness and depth of flavor.
Can I use a different sweetener instead of honey or maple syrup?
Yes, you can try agave nectar or coconut nectar as alternatives, but avoid granulated sugar in the batter since the texture and moisture balance rely on liquid sweeteners.
