Making Your Own Oat Flour Is Easy & Quick

Making oat flour is surprisingly easy. Simply pour rolled oats or quick-cooking oats into a food processor or a high-powered blender and process until you achieve a fine flour-like texture. The oat flour will not have the same texture as regular, all-purpose flour. It will be a little bit less fine and will have some chunks of oats in it.

Tips for Success

Get ready to make the best banana bread recipe with oat flour you could possibly imagine. Just follow these simple tips and tricks and you'll be on your way.

Make sure the bananas a brown enough. The browner the better here. Over-ripe bananas add sweetness and moisture to the banana bread that under-ripe or yellow bananas do not. If your bananas aren't quite ripe enough, pop them in the oven at 350 degrees for 20 minutes, let them cool, and incorporate them into the batter.
Don't over-mix. Over-mixing the batter will end you with a tough, overly dense loaf. So, when making the batter, be sure mix only until everything is just incorporated. The batter will not be perfectly smooth and that's ok.
Add the bananas last. Adding the bananas to the batter last ensures that you still get some good chunks of banana scattered throughout the bread.
Brown sugar. Consider sprinkling some brown sugar on top of the loaf before baking. This will yield a sweet, crunchy top.
