Oat Flour Cookies are perfectly chewy and made with whole-grain oat flour. If you’ve been curious about swapping gluten-free oat flour for all-purpose flour, you’ll love these!
Oat flour chocolate chip cookies will quickly become a staple in your home if you love the affordability and convenience of oat flour. They have a hint of oatmeal flavor, with a tender chewy center.
If you don’t keep oat flour in your pantry, you can make homemade oat flour by blending rolled oats in a blender or food processor. Once it has a fine texture, it’s ready to use in this recipe.
Use any leftover oat flour to make oat flour pancakes, banana bread, or sugar cookies.
Ingredients You’ll Need
Inspired by classic chocolate chip cookies, this recipe swaps white flour for oat flour and white sugar for coconut sugar. You can also use brown sugar if that’s what you have on hand. They taste amazing, either way!
If you need a dairy-free cookie, use your favorite vegan butter as an easy swap. (I like Miyoko’s brand.) Make sure your dark chocolate chips are dairy-free in that case, too.
If you need a vegan recipe, you can use a flax egg, too! (See the substitution notes below the recipe for tips.)
Allergy Note: Oats are naturally gluten-free, but they may be contaminated with gluten-containing products during processing. Look for a “certified gluten-free” label on the packaging when shopping for gluten-free oats or oat flour.
How to Make Oat Flour Cookies
Preheat the oven to 350ºF and line a large baking sheet with parchment paper. In a large mixing bowl, mix the softened butter and sugar.
Add in the egg and vanilla extract, and stir again.
Next, add in the dry ingredients, including oat flour, baking soda, and salt. Stir well until the cookie dough looks thick, then fold in the chocolate chips.
Now add in the dry ingredients, including baking soda, salt, and the oat flour.
Use a tablespoon or 1-ounce cookie scoop to scoop the dough onto the prepared pan. Just like regular cookies, they will spread as they bake, so arrange them 2 inches apart from each other.
Bake at 350ºF for 8 to 11 minutes, depending on how crispy you like cookies. The shorter the cooking time, the more gooey the centers will be.
These oat flour cookies will be very fragile while they are hot, so let them cool on the pan for at least 15 minutes before you transfer them to a cooling rack. Leftovers can be stored on a plate at room temperature for up to 48 hours, but if you place them in a bag they will soften significantly.
For the longest shelf life, store these cookies in an airtight container to chill in the fridge or freezer. (They are even tasty when you eat them frozen!)
Frequently Asked Questions
Yes, for oatmeal chocolate chip cookies, replace 1/4 cup of the oat flour with a 1/2 cup of rolled oats, which will add texture to the baked cookies. For classic oatmeal cookies, you can replace the chocolate chips with raisins.
Yes! But, you won’t use a 1:1 ratio in terms of measuring cups. Instead, you need to replace the flour by its weight, because all-purpose flour weighs more than oat flour. To replace all-purpose flour, multiply the measurement by 1.4 to get the measurement (in cups) that you need for oat flour.
For example, a classic chocolate chip cookie recipe calls for 1 1/4 cups flour. If you multiply 1.25 x 1.4 you get 1.75, so that’s how much oat flour you need to use in this recipe.
Compared to all-purpose flour, oat flour has more fiber, protein, and minerals.
Yes, you can shape the cookie dough balls and arrange them on a baking sheet, as if you are going to bake them. Then place them in the freezer to firm up for 30 to 60 minutes. Transfer the balls to an airtight container and freeze for up to 6 months. Let them thaw as you preheat the oven, then bake normally. They may need 1 to 2 additional minutes of cooking time.

Ingredients
- ½ cup softened butter (I use salted butter)
- ¾ cup coconut sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 1 ¾ cup oat flour (see notes)
- ½ teaspoon baking soda
- ½ teaspoon fine sea salt (I use Real Salt brand)
- ¾ cup dark chocolate chips
Instructions
- Preheat the oven to 350ºF. In a large bowl, mix together the softened butter and coconut sugar until they look relatively creamy.
- Add in the egg and vanilla and mix again. Then add in the dry ingredients, including the oat flour, baking soda, and salt. Mix well, until the batter looks thick and uniform. Fold in the chocolate chips.
- Use a 1-ounce cookie scoop, or heaping tablespoon, to scoop the dough and drop it onto a large baking sheet lined with parchment paper. Arrange the mounds of dough about 2 inches apart from each other, to allow for spreading as they bake. Bake at 350ºF for 8 to 11 minutes, depending on how crispy you like your cookies.
- Let the cookies cool on the pan for at least 20 minutes; they will be very fragile when hot from the oven. These cookies can be served warm or at room temperature after that, but they will soften and start to crumble if you store them in a bag at room temperature overnight. For a firmer texture, store them in the fridge for up to a week.

Can I substitute banana for sugar?
Hello there,
If I would like to reduce the amount of sugar, what can I adjust the recipe?
Thank you.
Sugar helps the cookies spread and adds moisture, so if you choose to reduce it I would expect the cookies to not spread as much and they will probably have a drier texture. You could reduce the flour a bit to help compensate for that, but it will be a bit of an experiment! Hope you enjoy them.
I’ve been looking for a somewhat anti inflammatory recipe for cookies and decided to try these! Just had one straight out of the oven and they are so good!! I substituted the coconut sugar for maple syrup, a half cup and I added about 4-5 tablespoons of buckwheat flour. I also used dark chocolate that I had lying around.
Loved this recipe! Can we freeze half the dough?!
Yes, definitely! I like to freeze the dough in mounds, so they thaw easily later.
Substituted vegan butter and flax egg in; tasted pretty good…though next time I’ll pull them out at 8min for a softer cookie. I couldn’t locate the weight of oat flour so did my best to scoop and squish. I also may switch to a chai egg instead as I found the flax quite obvious in the texture. But they are kid approved, my 5yo really enjoyed them with a class of milk.
This recipe is so delicious!! I substituted the coconut sugar for 3/4 maple syrup. The flavor was outstanding! The cookies were very crumbly though. Any suggestions to tweak for next time?
Came across this recipe looking for healthier options after my detox cleanse. At first I thought I made the batter all wrong but WOW! They came out perfect and were soooo delicious! Even my family liked them!
These cookies were fantastic! I ground up some rolled oats and weighed the ingredients and they came out perfect. The only modifications I made were adding an extra teaspoon of vanilla (I measure vanilla with my heart) and because some reviews said they didn’t spread well, I was worried about that happening and I added a spoon of maple syrup. It turns out the dough was moist enough and probably didn’t need it, but my cookies spread in the oven just like your photos. I used a cup when they were still warm to shape them into perfect circles. Loved the crisp edges and soft center. Such a lightweight and delicate cookie. My boyfriend loved them too. This recipe is a keeper!
