Note about bananas
The best bananas to use in banana bread are ones that are very ripe. The more brown the skin is, the better. This is because bananas become sweeter as they ripen. So you'll want to use the ripest bananas you can for the best results!
Oat flour banana bread step by step
In a large bowl, mash the bananas with a fork until no large chunks remain (step 1 above).
Add the eggs, honey and vanilla extract and mix until combined (step 2).
Add the oat flour, baking powder, xanthan gum and salt (step 3).
Use a large spoon to mix until fully incorporated, about 30 seconds (step 4).
Baking & serving
Line an 8" x 4.5" baking pan with parchment paper and spray with cooking spray.
Pour the batter into the pan and let it rest for 30 minutes before baking.
When the rest time is almost over, preheat the oven to 350F. Bake the loaf for 45 minutes or until a toothpick is inserted and comes out clean. Start checking at the 40-minute mark.
When the loaf tests done, remove the bread from the oven and place the pan on a wire rack to cool for 20 minutes. After 20 minutes, remove the bread from the pan to cool completely. When the bread is fully cooled, slice it and serve!
1. Weigh ingredients
It's always a good practice to weigh out ingredients, as this is the most accurate way to measure them. Use a scale to weigh the ingredients (in this case, the oat flour) that have a weight next to them.
2. Use room-temperature ingredients
Let all of the ingredients come to room temperature before you start. This will ensure that they thoroughly combine with each other.
3. Let the batter rest
After the batter is all mixed together, let it rest for a full 30 minutes before you put it into the oven. This bread needs the rest time so it will properly rise while it bakes.
4. Start checking the bread after 40 minutes
After it has been in the oven for 40 minutes, start checking the bread to see if it's done. The banana bread is done if a toothpick is inserted and comes out clean. You don't want it to be overdone because it will lose moisture the longer it bakes.
Yes, and it's a great option if you don't want to purchase premade oat flour. Process gluten free oats in a food processor for 5-6 minutes until it reaches a fine texture.
I highly recommend letting the batter rest for 30 minutes before baking. If you put it straight into the oven, the bread won't rise properly.
Yes! If you want it to last longer, slice the banana bread and keep them in the freezer. Defrost in the microwave for 30 seconds to 1 minute and enjoy!
