- Add oats to a blender and process until oats have broken down into flour.
- Allow oat flour to cool for 5 minutes and add to storage container with lid.
- Oat flour can be stored at room temperature, up to 1 month.
You can make a large batch of oat flour if you plan on using it often and want to keep on hand. Or you can make it as needed – I like my NutriBullet for this.
