Did you know you can make your own oat flour for pennies on the dollar vs store bought? So many recipes now call for flours much different than the All-Purpose or Whole Wheat that we are used to.

Almond flour, rice flour and oat flour have become common among ingredient lists.  If these flours are not something you regularly use,  it can be pricey to buy a bag that you may only need for a small amount.

You don’t have to spend a lot of money because you already have everything you need in your pantry to make your own oat flour, simply and inexpensively.

While oats are naturally gluten free, they can be cross contained depending on where they were processed. If you are looking for certified gluten free oat flour, all you need to do is make sure the oats you purchase say “certified gluten free” and then you can make your own gluten-free oat flour at a fraction of the cost.
