Can I Use Oat Flour Instead of All Purpose Flour?

You sure can… however it’s not a 1 for 1 conversion.

Oat flour is actually much lighter in weight than all purpose flour, so you may need to add more oat flour than a recipe with all purpose flour calls for.

A kitchen scale will come in handy when measuring. 🙂

Ingredients 

  • 1 1/2 cups Old Fashioned Oats, (Rolled Oats)

  • Storage tip: Oat flour can be stored in an airtight container for up to 3 months.

Notes

  • This recipe yields 1 1/4 cups of Oat Flour.
  • For a larger batch, recipe can easily be doubled.
