Oat Flour Chocolate Chip Cookies
These oat flour cookies are soft, chewy and so easy to make. They’re naturally gluten free, filled with chocolate chunks or chips and can be made refined sugar free. The perfect recipe to satisfy your sweet tooth!

Chocolate chip cookies are slowly becoming an Eat With Clarity specialty. We have probably over a dozen different recipes on the blog already, all so delicious in their own right.
My classic gluten free cookies and flourless peanut butter cookies are among my favorite, but these oat flour cookies are definitely up there on the list.
I love using oat flour in things like banana bread and pancakes, but until recently hadn’t tried in cookies! I love the chewy texture oat flour gives to cookies and it makes them completely gluten free too.
I generally don’t recommend replacing regular all purpose flour with oat flour in most recipes, so it’s best to follow a recipe that already calls for oat flour, like this one or my oat flour brownies.
Oat flour is a healthier option for baking because it has a higher fiber and protein content than white flour. It yields a cookie that’s chewy on the inside yet slightly crisp around the edges.

Key ingredients
OAT FLOUR. Oat flour of course makes up the base of these cookies! Be sure to use spoon and level the flour.
CORNSTARCH. This will help absorb a bit more of the wet ingredients and ensure the cookies are well held together.
SUGAR. A mix of light an brown sugar will give these cookies a delicious flavor an ensure the edges are crisp but centers are nice and soft!
BUTTER. I used regular butter, but you can use a dairy free butter like Earth Balance if you are dairy free.
EGG. One egg will help bind all ingredients together.
CHOCOLATE. I love using a chopped up chocolate bar, but regular chocolate chips are also great!

How to make oat flour cookies
Cream butter and sugar. Add the softened butter to a large bowl or bowl of a stand mixer with both sugars.
Add all wet ingredients. Beat together until smooth, about 30 seconds. Cream in the egg and vanilla.
Add dry ingredients. Beat in the dry ingredients aside from the chocolate. Be sure to spoon and level the flour, don’t scoop from the bag.
Chill dough. Fold in the chocolate chips or chunks. Add the dough to the fridge for 1 hour.
WANT TO SAVE THIS RECIPE?
Scoop. During the final few minutes, preheat the oven to 350 degrees Fahrenheit. Use a large cookie scoop (about 2 1/2-3 tablespoons) and scoop the dough into balls.
Bake. Press on a few extra chocolate chunks on top. Bake for 12-16 minutes or until just golden brown around the edges. Remove from the oven and let cool before serving. Sprinkle with salt flakes and enjoy!

Are oats gluten free?
Yes! Oats and oat flour are naturally gluten free.
However, if you have Celiac like me (or are making these for someone with Celiac) be sure to use certified gluten free oat flour since oats are often contaminated with gluten during processing.
You can make oat flour by simply grinding up old fashioned or quick oats in your blender or food processor. Be sure to let it run for a while until the flour is very fine.

Why do I have to chill the dough?
For a few reasons! One, it helps a lot with the flavor. Think of how much more flavor you get when you marinate things like chicken or tofu.
Letting cookie dough rest in the fridge allows all of the flavors to blend together and yield a much more flavorful cookie.
Second, you need to chill the dough so the cookies don’t spread too much while baking.
This gives the oat flour and cornstarch a chance to absorb some of the wet ingredients in the dough and prevents the cookies from spreading completely flat.

Can I make them vegan?
I have not tested these oat flour cookies without egg, but since there is only one in the recipe, I imagine a flax egg or even apple sauce would be fine.
If using apple sauce, use 3 tablespoons or make 1 flax egg with 1 tablespoon of ground flax with 3 tablespoons of water.
Can I make them refined sugar free?
You can sub both of the sugars for coconut sugar, but keep in mind the color of the cookies will be much darker than pictured. They will also spread differently and the overall flavor will be different.
I use a stevia sweetened chocolate bar to cut down on the sugar a bit, but any kind of chocolate or chocolate chips will work here!

I just made these. They sure did spread out during baking. I did refrigerate for an hour before baking.
Even though they really spread out and are quite thin, they are tasty and I will make them again. They donโt look like the photo but Iโm still happy with them. -
I never leave reviews on gluten free recipesโฆbut this oneโฆ OMG. SO FREAKIN GOOD! Iโm dairy free, so I used โMeltโ brand DF butter, and then bobs red mill oat flour and these turned out sooo good!
Iโve tried many recipes, most of which call for the premixed gluten free flour, but the texture can be hit and miss. I knew I wanted to try regular gf oat based ones, and Iโm SO happy I tried this one.
My 4 year old loved them, and my hubby, who never eats my GF treats, had to be stopped from eating them all lol Definitely recommend!

Love that! Glad they were a hit with the family!

Turn out great. IJust add 1 tbs of white sugar instead of 1/2 cup. I find the sweetness can reduce further to my taste. Thanks
-
Love it! Used 1/4 almond flour for the additional oat flour. Subbed 1/2 c allulose for white sugar, otherwise the same. Turned out great! They keep 6 days!
-
Glad those subs worked! Thanks, Melissa!

I brought these to a family gathering for one person who has a gluten allergy. All 10 cookies were gone in a matter of seconds. Everyone loved them and wanted more! They couldnโt believe that theyโre gf. Iโve never made something and had so many people ask for the recipe! 100/10
