  • Turn off the food processor and use immediately or transfer to an airtight container.

Notes

Storage
  • Leftover oat flour can be stored in an air-tight container in a cool, dry place for up to 3 months.
Top Tips
  • Use organic oats if you can. According to EWG, glyphosate is often found in non-organic oat-based products.
  • Ensure that your blender or food processor is clean and dry before adding the oats. Moisture can cause the oats to clump.
  • Use rolled oats or old-fashioned oats because they are easier to blend into a fine flour than instant oats.
  • If using oat flour instead of all-purpose flour, note that 1¼ cup of unpacked and leveled oat flour replaces 1 cup of all-purpose flour. 
  • Since oat flour has a high level of soluble fiber, you may need more liquid or fat to yield similar results as a replacement for all-purpose wheat flour.
