Ingredients

  • 1 ½ cups rolled oats (gluten-free friendly as needed)

Instructions

  • Add oats to a high-speed blender and blend on high until a fine, powdery flour is achieved — about 15 seconds (it’s fast!). Be careful not to overblend or the oat flour will get clumpy.
  • Check your blender for bits of oats and continue blending, occasionally removing your blender from the base and shaking to ensure all oats are well blended.
  • Transfer to a jar or container and store up to 1 month unrefrigerated, often longer. See above for recipe suggestions.

    Can I Substitute oat flour for one of these flours: almond, coconut, hazelnut or cassava flour?

      Hmm, that’s a good question. We’ve never tried that, but it might work? Let us know if you try it out!

    Hi! Would 1-minute quick oats be okay to use for this? I have a whole container of Quaker gluten-free oats of this kind and want to avoid having to buy more (and having to go back to the store for the 6th time…).
    I hope your day is a beautiful one ✌️♥️?
    PS. I’m making your pumpkin soup again… it’s one of my favorite things to make and have for food prep. Which reminds me, I’m wondering if I were to roast the pumpkin and put it in the fridge until the next day or the day after that, it it would still be good to use (I tend to cook at night, my blender is very loud, noise echoes in my apartment, and I have next-door and upstairs neighbors…).
    Thank you for your help! :)

      Hi Charu, unfortunately, it doesn’t. We like to use a combination of gluten-free flours to best simulate the texture of wheat-containing products.
