How To Make Oat Flour

Oat flour has a soft texture and subtle nutty flavour.  If you use certified gluten-free oats, oat flour is gluten-free.  

– Old-fashioned oats, quick-cooking oats or steel-cut oats (certified gluten-free if necessary)


Make oat flour as needed or in bulk to store. Half-fill your blender or food processor with oats.   


Step 1

Remember that one cup old-fashioned or quick-cooking oats generates one cup flour, while one cup steel-cut yields two.  

Step 2

To flour oats, blend 20–1 minute. If your blender has a broad base and mixes badly, add extra oats.   

Step 3

Done when flour feels like powder with a slight texture (not sand). Larger oat specks require longer blending.  

Step 4

Extra flour can be stored in a labelled airtight jar for 3 months.

Step 5

Healthy natural oils make whole grain flours last less than processed flours.
