Essential Ingredients for Oat Banana Bread

This wholesome and comforting quick bread comes together with a handful of simple pantry staples.

  • Oats: 2 cups of old-fashioned rolled oats (or 2 cups of pre-made oat flour)
  • Bananas: 3 large, very ripe bananas, mashed
  • Sweetener: ½ cup of maple syrup or honey
  • Eggs: 2 large eggs, at room temperature
  • Fat: ⅓ cup of melted coconut oil or other neutral oil
  • Leavening: 1 teaspoon of baking soda
  • Flavor: 1 teaspoon of vanilla extract & 1 teaspoon of ground cinnamon
  • Salt: ½ teaspoon of salt

Ingredients Notes

A little more detail on our key ingredients will ensure your banana bread is perfectly moist and delicious.

  • The Oat Flour: Oat flour is a fantastic, naturally gluten-free flour that gives this banana bread a wonderfully tender texture and a wholesome, slightly nutty flavour. You can easily make your own oat flour at home by simply blending rolled oats in a high-speed blender. Be sure to use certified gluten-free rolled oats if you need this recipe to be strictly gluten-free.
  • The Bananas: For the absolute best and most flavourful result, it is crucial to use very ripe, almost overripe, bananas. You are looking for bananas that have a lot of deep brown and black spots on the peel. These bananas are much sweeter, have a more intense banana flavor, and their soft texture makes them very easy to mash into the batter.
  • The Sweetener: To keep this recipe refined sugar-free, we use a natural liquid sweetener like pure maple syrup or honey. They both add a wonderful, complex flavour and the perfect amount of sweetness to the bread.
  • The Coconut Oil: Using melted coconut oil not only keeps this recipe dairy-free, but it also adds a beautiful, subtle complementary flavour and contributes to the wonderfully moist texture of the final loaf. You can also use another neutral-flavored oil if you prefer.

How to Make One-Bowl Oat Banana Bread

Let’s walk through the incredibly simple one-bowl process for creating this perfectly moist and wholesome banana bread.

  • Step 1: Prepare Your Oven and Make the Oat Flour. First, preheat your oven to 175°C (350°F) and grease and flour a standard 9×5 inch loaf pan. If you are making your own oat flour, place 2 cups of rolled oats in a blender and blend on high until a fine, soft powder is formed.
  • Step 2: Combine the Wet Ingredients. In a large mixing bowl, mash your very ripe bananas with a fork until they are mostly smooth. Whisk in the maple syrup, the eggs, the melted coconut oil, and the vanilla extract until everything is well combined.
  • Step 3: Add the Dry Ingredients. To the same bowl with the wet ingredients, add the oat flour, the baking soda, the ground cinnamon, and the salt.
  • Step 4: Gently Mix the Batter. Use a spatula to gently fold the dry ingredients into the wet ingredients until they are just combined. Be very careful not to overmix the batter; a few small lumps are perfectly okay.
  • Step 5: Bake to Golden Perfection. Pour the batter into your prepared loaf pan and spread it into an even layer. Bake for 45 to 55 minutes. The banana bread is done when it is a deep golden brown on top and a toothpick inserted into the center comes out clean.
  • Step 6: Cool and Enjoy. Let the banana bread cool in the pan on a wire rack for at least 15 minutes before you carefully invert it to remove it from the pan. Let it cool completely on the wire rack before you slice and serve it.

Storage Options

This beautifully moist oat banana bread stays fresh for a long time. Once the loaf has cooled completely, you can store it in an airtight container or wrap it tightly in plastic wrap at room temperature for up to 4 days. The flavour and wonderfully moist texture are often even better on the second day.

This bread also freezes wonderfully. You can wrap the entire cooled loaf or individual slices in plastic wrap and then in a layer of foil, and it will keep in the freezer for up to 3 months.

Variations and Substitutions

This classic recipe is a wonderful and versatile template that you can easily adapt. For a delicious crunch, you can fold in about a cup of chopped walnuts or pecans to the batter along with the dry ingredients. For a more decadent, treat-style loaf, feel free to add a cup of your favorite chocolate chips to the batter.

Practical & Valuable Tips

For the absolute best flavour, always use the ripest bananas you can find; the browner and spottier, the better! The most important tip for a tender and soft loaf is to not overmix your batter once you have added the oat flour. Finally, allowing the bread to cool completely before you slice into it is a crucial step that will ensure you get beautiful, clean slices that don’t crumble.

Frequently Asked Questions

  1. Can I use steel-cut oats to make the oat flour? No, it is not recommended to use steel-cut oats for making oat flour. You should use old-fashioned rolled oats or quick-cooking oats, as they are much softer and will blend into a fine, soft powder. Steel-cut oats are much harder and will not create a flour with the correct texture.
  2. My banana bread is very dense. What did I do wrong? A dense texture in oat banana bread is usually a result of overmixing the batter after the flour was added. Be sure to mix the batter just until the flour is incorporated and no longer. It could also be that your baking soda was not fresh, so be sure to check its expiration date.
  3. Can I make this recipe vegan? Yes, this recipe can be easily adapted to be vegan. You would simply need to substitute the two eggs with two “flax eggs” (2 tablespoons of ground flaxseed mixed with 6 tablespoons of water) and ensure you are using maple syrup instead of honey.
  4. How do I keep my add-ins, like chocolate chips or nuts, from sinking to the bottom? A great and simple trick is to toss your chocolate chips or nuts in a tablespoon of oat flour before you gently fold them into the batter at the very end. This light coating of flour helps them to stay suspended in the thick batter as it bakes.
  5. How do I store the oat banana bread to keep it fresh? The best way to store this bread is to let it cool completely and then wrap it tightly in plastic wrap or place it in an airtight container. It will stay wonderfully moist at room temperature for about 4 days.
