FREQUENTLY ASKED QUESTIONS
Yes. Each time I tested the recipe, I tried a different amount of sugar. The amount included in the recipe mimics a more old-fashioned banana bread taste, but the bananas’ sweetness means you don’t have to add as much. Reduce the sugar down to 1/3 cup or replace it with an unrefined sweetener.
Yes, since this recipe contains no flour, only oat flour, it is naturally gluten free. Using certified GF oatmeal means they were processed on equipment free of wheat, barley, or any other contaminants, and are safer to eat.
Yes, but you will need to purchase oat flour. First whisk together the dry ingredients in a large bowl – oat flour, baking powder, baking soda, and salt. In a separate bowl, mash the bananas and whisk in the eggs, milk, brown sugar, oil, and vanilla.
Add the liquid ingredients to the dry, mixing well. Stir in the remaining 1 cup oats and pour into a greased loaf pan. Bake as directed.
Oat flour banana bread contains a lot of moisture, so you need to make sure it has plenty of time for the liquid to be absorbed in the oats, even if the crust appears done.
Insert a long skewer or knife in the middle to double check the bread is cooked through and not wet in the center. Even if the crust appears set and browned, it’s a good idea to always check with banana bread.
For best results, let the bread cool about 20-30 minutes before slicing. After it has cooled completely, store in an airtight container at room temperature up to 3 days.
To freeze, slice completely cooled bread and store in a ziplock freezer bag, with air removed, up to 3 months.
More tips / suggestions
- To make oat flour, blend the oats until it turns into a fine, powdery flour, about 30 seconds – 1 minute. Check to be sure you don’t have any larger flecks of oats, and if so, blend again.
- Add 1/2 cup miniature chocolate chips for oatmeal banana chocolate chip bread, 1 cup chopped pecans or walnuts for banana nut bread, and/or 1 teaspoon ground cinnamon.
- If your bread pan doesn’t have a good non-stick finish, you may want to line it with a piece of parchment paper so the bread releases easily.
- If the bread is becoming overly browned, loosely tent foil over the top for the last 20-25 minutes.

I have pre-ground oat flour from Bob’s Red Mill. Can I use this & if so, what amount? 2nd question is what is the weight of the 3 bananas? We get really small ones & really big ones so they can vary by as much as 25 grams each. Thanks for this recipe – can’t wait to try it!
Melissa says
Hi Lisa,
I’d be happy to help! The conversion is 1-to-1 for pre-ground oat flour. So you would use 2 1/2 cups oat flour, but still have to stir in the old-fashioned oats later in the recipe.
For the bananas, it’s about 1 pound of bananas. If there were mashed, it would be about 1 cup.
Enjoy the recipe!
Best,
Melissa
