  1. Do you measure the oat flour after its blended?

    1. If you’re using it in a recipe, yes. You should measure it after it’s been blended. It will be pretty close!

  2. 5 stars

      no you cant, sorry!

    I wanted to make your banana muffins (they look delicious!) but I do not have oat flour on hand. I have accidently purchased 1 minute instant oats (twice!), so can I use instant oats to make oat flour?

    1. The Clean Eating Couple says:

      Yes you can! They will work just fine 🙂
