Notes

  • If there are a few large pieces that just won’t blend, simply sift them out with a fine-mesh strainer. 
  • Once the rolled oats have been processed into flour, their shelf life does shorten a bit. Be sure to store them in an airtight container in a cool dark place away from direct sunlight.
  • If you do not have a blender, a strong food processor will work as well.
  • Make sure to purchase certified gluten-free rolled oats if you require the flour to be gluten-free. While oats are naturally gluten-free, you cannot guarantee that all rolled oats are gluten-free due to cross-contamination at the processing center. Oats labeled gluten-free are processed in a gluten-free facility.
