Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

2 cups rolled oats
3 ripe bananas, mashed
2 large eggs
1/2 cup plain Greek yogurt
1/4 cup honey or maple syrup
1 teaspoon vanilla extract
1 teaspoon baking soda
1/2 teaspoon baking powder
1/2 teaspoon salt

For the cinnamon swirl:
2 tablespoons coconut sugar or brown sugar
1 teaspoon ground cinnamon

Directions

Start by preheating your oven to 180°C (350°F). Lightly grease a loaf pan or line it with parchment paper to prevent sticking.

In a blender or food processor, blend the rolled oats until they reach a fine flour-like consistency. This step ensures a smooth texture in the final bread.

In a large mixing bowl, combine the mashed bananas, eggs, Greek yogurt, honey, and vanilla extract. Whisk everything together until the mixture is smooth and well incorporated.

Add the oat flour, baking soda, baking powder, and salt to the wet ingredients. Stir gently until a thick batter forms. Be careful not to overmix, as this can affect the texture.

In a small bowl, mix the coconut sugar and cinnamon to create the swirl mixture.

Pour half of the banana batter into the prepared loaf pan. Sprinkle half of the cinnamon mixture evenly over the batter. Add the remaining batter on top, then finish with the rest of the cinnamon mixture. Use a knife or skewer to gently swirl the cinnamon into the batter.

Bake for 40 to 50 minutes, or until a toothpick inserted into the center comes out clean. Let the bread cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.

Slice and enjoy once cooled.

Servings and timing

This recipe makes about 8 slices of banana bread. Preparation time is approximately 10 minutes, while baking takes around 45 minutes. Including cooling time, the total time is about 1 hour and 10 minutes.

Variations

You can easily customize this banana bread to suit your taste. For a richer flavor, add 1/3 cup of dark chocolate chips to the batter. If you prefer a nuttier texture, mix in chopped walnuts or almonds.

For a dairy-free version, replace the Greek yogurt with a plant-based yogurt alternative. You can also swap honey for maple syrup to keep it fully plant-based.

To enhance the spice profile, consider adding a pinch of nutmeg or cardamom along with the cinnamon. If you like a sweeter loaf, increase the sweetener slightly or add a drizzle of honey on top after baking.

Storage/Reheating

Store the banana bread in an airtight container at room temperature for up to 2 days. If you want to keep it fresh longer, refrigerate it for up to 5 days.

For freezing, wrap individual slices tightly in plastic wrap and place them in a freezer-safe bag. They can be stored for up to 2 months. Thaw at room temperature or warm gently in the microwave.

To reheat, place a slice in the microwave for about 15 to 20 seconds, or warm it in a toaster oven for a slightly crisp edge.

FAQs

Can I use quick oats instead of rolled oats?

Yes, quick oats work just as well and will blend more easily into a fine flour.

What if my bananas aren’t very ripe?

Ripe bananas are key for sweetness and moisture. If yours aren’t ripe, the bread may be less flavorful.

Can I make this recipe vegan?

You can replace the eggs with flax eggs and use plant-based yogurt and maple syrup.

Why is my banana bread dense?

Overmixing the batter or using too much oat flour can lead to a dense texture.

Can I skip the cinnamon swirl?

Yes, but it adds a lot of flavor. Without it, the bread will be simpler but still tasty.

How do I know when it’s fully baked?

Insert a toothpick into the center. If it comes out clean, it’s ready.

Can I add protein powder?

Yes, but reduce the oat flour slightly to maintain the right consistency.

Is this bread gluten-free?

If you use certified gluten-free oats, then yes, it is gluten-free.

Can I make muffins instead of a loaf?

Absolutely. Divide the batter into a muffin tin and bake for about 20–25 minutes.

How should I serve it?

It’s delicious on its own or with a spread of nut butter for extra richness.

Flourless cinnamon swirl banana bread is a wholesome twist on a classic favorite. It combines simple ingredients with comforting flavors to create a loaf that feels both nourishing and indulgent.
