Hi Bold Bakers!

Whether you eat gluten-free or not, learning how to make your own oat flour is satisfying and adds a lovely taste and texture to your baking. Be sure to check out my other two gluten-free flours, Almond Flour and Chickpea Flour, too!

Making your own gluten-free oat flour couldn’t be easier, and all you need is one ingredient — oats! Even if you aren’t gluten-free, oat flour recipes are absolutely delicious. It’s a fantastic flour substitute, but it also gives a great texture and flavor to cakes, cookies, my homemade oat flour pancakes, and loads of delicious desserts! 

I’m sure you have plenty of questions about baking with oat flour versus all-purpose flour, so let’s get into the nitty-gritty!

What Type Of Oats Should I Use?

If you’re wondering what kind of oats can be used to make this flour, the answer is old-fashioned rolled oats or quick-cooking oats. All you have to do is pour your oats into a blender or food processor (one of my savvy Bold Bakers even mentioned using a coffee grinder!) and blend until the oats turn into a fine powder, not unlike AP flour. 

How Much Oat Flour Equals Regular Flour?

This flour has a different density and texture than AP flour. If your recipe calls for 1 cup of regular white flour, substitute it for 1 1/3 cup of oat. If the batter or dough seems too stiff, add a little more liquid. Get the full recipe down below.

Gemma’s Pro Chef Tips

  • Be sure to sieve the flour after you blend it to remove any lumps of oats.
  • Flour made from oats works wonderfully in recipes that call for eggs. Since it is gluten-free, eggs add the missing structure to a recipe. 
  • When baking with oat flour, especially pancakes, I let the batter rest to make sure all the ingredients have the time to meld together. 

How Do I Store Oat Flour?

You can store your flour in an airtight container for up to 8 weeks! If you pop it in the fridge, it will also have a longer shelf-life.

Can steel cut oatmeal be used to make flour? I accidentally bought some when I meant to pick up quick oatmeal.

Hi, have been following you for a while…you are so amazing…that for wonderful stuff.

2 questions

1. Do we have to roast oats before grinding or after grinding for your no bake cookies recipe?
2. Can we take any other type of oats…or it has to be rolled oats only?

Thanks so much
