INGREDIENTS – Old-fashioned oats, quick-cooking oats or steel-cut oats (certified gluten-free if necessary)
Instructions: 1. To make oat flour, you can prepare it as needed or create a larger batch for future use.
Fill your blender or food processor halfway with oats. Note that one cup of old-fashioned or quick-cooking oats yields about one cup of flour, while one cup of steel-cut oats yields about two cups of flour.
Blend the oats until they turn into a fine flour, which typically takes about 20 seconds to 1 minute.
If you're using a blender with a wide base and it's struggling to blend well, add more oats as needed.
The flour is ready when it resembles powder with a very slight texture; it should not feel like sand. If you notice any larger flecks of oats, blend for a bit longer.
Store any extra flour in a labeled, airtight container for up to 3 months. Keep in mind that whole grain flours contain natural oils and do not have the same shelf life as refined flours.
