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.
Blend until the oats have turned into a fine flour, about 20 seconds to 1 minute.
The flour is done when it feels like powder with a very slight texture.
Store extra flour in a labeled air-tight container for up to 3 months.
