Whenever I have overripe bananas sitting in the fruit bowl, I know it’s time to bake up some banana bread. It’s a classic for a reason: this simple loaf cake is quick to make, and my kids love it with some cinnamon toast crunch milkshake! This version uses oat flour in place of white wheat flour for a whole grain twist that adds extra fiber while still yielding a soft, fluffy texture.

Ingredients Needed

Below are the ingredients you’ll need to make Oat Flour Banana Bread. The full quantities can be found in the recipe card further down the post.

Ingredients to make oat flour banana bread.
  • Bananas: Overripe bananas add natural sweetness, moisture, and that signature flavor to the banana bread.
  • Coconut sugar: Naturally sweetens the banana bread and adds a caramelized flavor. You can also use light brown sugar instead.
  • Coconut oil: Brings moisture and a light, coconutty flavor to the banana bread. You can also use olive oil or melted butter, if you prefer.
  • Eggs: Bind the batter and help the banana bread to rise, giving it a light, spongy texture.
  • Pantry Staples: Vanilla extract, Baking powder, baking soda, and Salt.
  • Oat flour: This fine, whole-grain flour is simply made from milled oats. It’s higher in fiber than white flour but makes baked goods that are lighter than those made with whole wheat flour.
  • Chocolate chips: An optional extra to fold into the banana bread to give it a sweeter, more dessert-like flavor. I like to use dark or sugar-free chocolate chips, but go with whichever you prefer.

How to Make Oat Flour Banana Bread

Before you start: Preheat oven to 350°F. Grease an 8×4-inch loaf pan with cooking spray and line with a piece of parchment paper.

Step 1: Add the mashed ripe bananas, eggs, coconut oil, vanilla, and sugar to a medium bowl. Mix well to combine. Set aside.

Step 2: In a separate bowl, mix the dry ingredients: oat flour, baking powder, baking soda, and salt.

Variations & Tips

  • Peanut Butter Banana Bread: Swirl 2-3 tablespoons of natural peanut butter into the batter just before baking.
  • Don’t have any oat flour? Make it yourself by blending rolled oats in a high-speed blender or food processor until broken down into a flour-like consistency. Here is how to make oat flour if you aren’t sure.
  • Try folding in chopped walnuts or pecans, or shredded coconut for some crunch.
  • Sprinkle the top of the batter in the loaf pan with a little extra coconut sugar for a nice, crunchy crust.
  • If you don’t have any ripe bananas, you can roast yellow bananas (in their peels) on a tray at 350F for 20-30 minutes until blackened to use instead.
  • As bananas vary in size, I like to measure the mashed banana before adding it to the batter. You need around 1 cup of mashed banana for this recipe.

Common Questions

How do I store it?

Let it cool, then store in an airtight container at room temperature for 5-7 days.

Can I freeze it?

Yes! Banana bread freezes really well. Let cool, then wrap in plastic wrap and foil. Freeze for up to 3 months. Thaw at room temperature before eating.

How can I keep banana bread moist?

Let the banana bread cool fully, then store it in an airtight container (or wrap it tightly in plastic wrap) and keep it at room temperature. Putting banana bread in the fridge will make it last longer, but will cause it to dry out more quickly.

Is oat flour gluten free?

While oats are a gluten-free grain, they are often contaminated with gluten-containing grains, such as wheat, during processing. Therefore, if you need this recipe to be gluten-free, make sure you’re using a certified gluten-free oat flour.
