Description

Learn how to make oat flour for all your gluten free baking needs! All you’ll need are gluten free oats, a blender, and a couple of minutes!


Ingredients

Units Scale
  • 23 cups gluten free oats (rolled, quick, or steel cut)

Instructions

  1. Place 1-2 cups oats in a high-speed blender or food processor at a time.
  2. Blend or pulse for around 45 seconds or until a fine flour-like consistency is formed. NOTE –  Steel cut oats may take longer to blend. Begin by blending the oats for 45 seconds, scrape sides, and repeat for a total of 90 seconds to 2 minutes or until a fine flour is formed. Transfer the ground oats to a glass jar or bowl.
  3. Repeat with the remaining oats. 
  4. Store at room temperature for 2-3 months. Or freeze up to 6 months.

Notes

Storage Tip – Whole grain gluten free flours contain natural oils. So, the shelf life is not as long as that of refined flours.  

Measuring Tip – In most cases, 1 ¼ cups of gluten free rolled oats makes around 1 cup of oat flour.
