Homemade Oat Flour
Learn how to make oat flour! It’s so easy. You’ll need old-fashioned (rolled) oats, quick-cooking oats or steel-cut oats, plus a blender or food processor. One cup old-fashioned or quick-cooking oats yields about one cup flour, whereas one cup steel-cut oats yields about two cups flour.
Ingredients
- Old-fashioned oats, quick-cooking oats or steel-cut oats (certified gluten-free if necessary)
Instructions
- You can make oat flour on an as-needed basis, or make a larger batch to save for later. Fill your blender or food processor up to half-way with oats. Keep in mind that one cup old-fashioned or quick-cooking oats yields about one cup flour, whereas one cup steel-cut oats yields about two cups flour.
- Blend until the oats have turned into a fine flour, about 20 seconds to 1 minute. (If you’re using a blender with a wide base and it’s not gaining enough traction to blend well, you’ll need to add more oats). The flour is done when it feels like powder with a very slight texture (it should not feel like sand). If you see any larger flecks of oats, blend longer.
- Store extra flour in a labeled air-tight container for up to 3 months. Since whole grain flours contain good-for-you natural oils, they do not last as long as refined flours.
Notes
Make it gluten free: Be sure to use certified gluten-free oats.
