Step 1

Add oats to a high-speed blender and blend on high until a fine, powdery flour is achieved — about 15 seconds (it’s fast!). Be careful not to overblend or the oat flour will get clumpy.

Step 2

Check your blender for bits of oats and continue blending, occasionally removing your blender from the base and shaking to ensure all oats are well blended.

Step 3

Transfer to a jar or container and store up to 1 month unrefrigerated, often longer. See above for recipe suggestions.
