These Oat Flour Cookies are so simple to make and gluten-free. They bake up soft and delicious – the perfect simple cookie to go with a cup of coffee or tea along side a Chocolate Chip Oatmeal Cookie.
These oat flour cookies are one of my favorite easy cookie recipes. They’re so simple, taste great, and have a wonderful texture.
It’s fun to experiment with alternative flour, and oat flour is a great one to use in cookies. Unlike all-purpose flour, oat flour doesn’t have any gluten as long as it’s labeled “certified gluten-free.” So it’s a great option if you’re avoiding gluten.
Since there’s no gluten, the texture of these cookies is soft and fluffy. Oat flour also has a light nutty flavor, and as you know, we love our nut cookies around here!
Oat flour is also more nutritious than white flour with more protein and fiber. So, even if you’re not following a gluten-free diet, these cookies are worth trying.
I can never resist a soft, warm homemade cookie and these oat flour cookies check all of those boxes.

- Brown sugar

How to make your own Oat Flour
In a food processor or blender add the rolled oats and pulse or blend until you have a fine, powdery flour. That’s it!
How to Make Cookies with Oat Flour
Whisk the flour, salt, baking powder, and baking soda in a small mixing bowl.
In a large bowl, beat the butter, sugar, egg, and vanilla with an electric mixer for about two minutes.
Add the dry ingredients to the butter mixture and mix to combine. If needed, add two to three teaspoons of water to bring the dough together.
Form the dough into golf ball-sized dough balls, roll them in demerara sugar, and place the cookie dough balls on a prepared baking sheet.
Bake the oat flour cookies at 350°F for 12 to 15 minutes. Allow them to cool for 10 minutes before serving them.
Recipe Tips to Make Oat Flour Cookies
- When you add the flour mixture to the wet ingredients, you may need to add a little water to moisten the dough, so it holds together. Start with one teaspoon and up to another teaspoon if needed.
- Don’t overbake these cookies. Once they are set around the edges and on top, they are done.
- You can make oat flour chocolate chip cookies by adding 1/2 cup of chocolate chips. Semi-sweet, milk, or dark chocolate chips will work well.
- You can also add chopped nuts like walnuts, peanuts, or pecans. If you want to do a mix of nuts and chocolate, only add a total of 1/2 cup.
- Dried fruit would also work well like dried cranberries or raisins.
Storage Tips for Oat Flour Cookies
Once the cookies are cooled, store them in an airtight container at room temperature. They will keep for several days.
You can also freeze them. Place the cooled cookies in a bag or airtight container and they will keep in the freezer for up two months.
