Certified Gluten Free Oats
We love GF Harvest Certified Gluten Free Rolled Oats. I use them in everything from overnight oats, to fruit crumble, to chocolate chip cookie dough bites.
You can find GF Harvest Oats on Amazon. They are made in a facility that is nut free as well as free from many other allergens.
You can also get certified gluten free oats that are made in an allergen free facility from Gerbs Allergy Friendly Foods.
Some other brands of oats to check out are Zego or Arrowhead Mills.
Step by Step Instructions
- Put your certified gluten free oats into a food processor, and process on high. It will take some time for the oats to be ground down into a fine flour. If you have a mini food processor, that should work, but you’ll have to grind smaller amounts of flour at a time.
- Continue to process the oats. This is what the oats look like after 30 seconds in the food processor – they are starting to break down, but there are still some larger pieces.
- As you continue to grind the oats, after 90 seconds you will see that they are ground down into a fairly fine flour.
- If you want to make sure that there are not any larger pieces left, you can sift it with a fine mesh sieve to make sure the flour is very fine and smooth. You can store your freshly ground flour in an airtight container or ziploc bag.
How to Use Oat Flour
You can use oat flour in many different types of recipes. This flour does lend a soft texture to baked goods, so you may want to substitute it for half the amount of flour in your recipe. For example, if the recipe calls for 1 cup of gluten free flour, you can use ½ cup of oat flour, and ½ cup of gluten free flour.
You can try to substitute oat flour for the full amount of flour in the recipe, but the texture of your cakes, cookies, or muffins may be very soft, or may become crumbly. Watch the baking time as well – it may be more or less depending on what you are baking.

If a small amount of oat flour is required a coffee grinder can be used.- works well – 1/2 cup oats is equals 1/2 cup ground oat flour
