I’m currently in full veg out mode. Lounging in bed way longer than anyone should ever stay in bed, watching Orange is the New Black, sipping my mug of coffee, and occasionally reaching over to pet my purring kitty. I need this today. My body is saying, “Thank you. Quit abusing me please!”

I have a week off of school (though I am still working most nights) and I plan to use it to recuperate from my sleep deprivation and to bake as much and as leisurely as possible.

I’ve been playing with oat flour a lot lately. I’m pretty into it. It gives baked goods a really lovely rustic texture and the perfect amount of chew.

It is also a great flour to use in vegan baking because oat flour has a much higher protein content than wheat flour which is helpful since we are nixing the eggs. I also love it in gluten free baking because the end result never feels like an alternative recipe.

Oats are a familiar flavor and texture for people and I think they feel less intimidating than some other alternative flours.

Making your own oat flour is so easy! All you have to do is put rolled oats (certified gluten free of course if you are gluten intolerant!) in a blender or food processor and pulse until it is the consistency of flour. The time for this will vary depending on the strength of your kitchen appliance.

Then, I always sift the flour. I don’t have a great blender so there is always a good deal of oat crumb that is too big to go through the sifter. So I add all of the bigger crumb back into the blender for one more whirl through, sift again, and store it all in an airtight container.

Of course you can always buy oat flour in the store. It’s a little pricier than making it yourself but a little more convenient if you don’t want to pull out your blender.

I really want you guys to try this recipe. Even if you aren’t vegan or gluten free. I promise it does not taste like an alternative to a traditional cookie. It is an amazingly simple and delicious dessert that just so happens to be vegan and gluten free.

And while you’re at it, you should check out these brownies and banana bread that I made with oat flour too. They just so happen to be vegan and gluten free as well and that bread has been blowing up like crazy on pinterest. Oat flour. Get into it.

  1. This cookie looks perfect. I love its rustic characteristics and the fact that you can see the coarse flour. Beautiful!

  2. Oooh these sound so yummy! I play a lot with oat flour too, mostly for my dogs who are allergic to wheat. I fully intend to find an excuse to make these this weekend! Breakfast maybe? They are oats… 😉

  3. You pretty much had my full attention at peanut butter. 🙂

  4. Mmmm I love oat flour! This skillet cookie looks increeeedible.

    I’m so glad you had a little time (semi) off!

  5. This recipe rocked my world. I’ve made it three days in a row. Don’t judge.

  6. do you have any vegan substitutions for the vanilla yogurt?

    • Hi Jordana,

      The kind I suggest in the recipe and that I used, SoDelicious Coconut Milk yogurt, is vegan. It works great and tastes delicious too. There are also various kinds of other vegan yogurts that are pretty easy to find.

  7. For making your own oat flour, does it matter if it’s either old-fashioned or quick oats?

  13. Hey Kristen! It’s Sarah Waltz! Long time no see! We are going to be stuck inside this weekend due to a winter storm and want to have something sweet on hand while we binge watch The Magicians. Can I use any old skillet to make this or does it need to be a cast iron?

    I love your website and recipes! I hope all is well with you and your hubby. My partner and I follow you on instagram (we’re @awestrek) and enjoy seeing the awesome food you cook up!
