Gluten-free oat flour cookies

After experimenting with oat flour recipes and homemade oat flour I am thoroughly sold! Sure, there are many ways to make a delicious gluten free chocolate chip cookies, but I particularly love oat flour chocolate chip cookies because…

1. It’s always available in my pantry. Just grab some old fashioned rolled oats or quick-cooking oats and you can make homemadeoat flourin minutes!
2. Oat flour is affordable. When writing my gluten-free cookbook, I experimented with many affordable gluten-free baking recipes. Making your own oat flour (please do), is cheaper than other gluten-free flours, such an all-purpose 1-to-1 blend, almond flour, or coconut flour.
3. The flavor is neutral and hom*ogenizes seamlessly, like inoat flour bread. Some gluten-free flours can be very strong tasting, such as sorghum, teff, or buckwheat, which are commonly used in blends. Oatmeal has a light, nutty taste that makes baked goods even more delicious!
4. Flourless cookie recipesconsistently turn out fabulous because there are no unpredictable ingredients involved.

2. To make the cookies, first cream together the softened butter and sugars until light and fluffy. Add the egg, vanilla extract, and combine well.
3. On low speed mix in the dry ingredients – oatmeal ground into oat flour, baking soda, and salt.

5. Divide spoonfuls onto ungreased cookie sheets or line with parchment paper. Bake at 350°F for 12-13 minutes.

making homemade oat flour for cookies

To make the best texture of cookie, you’ll want to use equipment that grinds the oats down as fine as possible. This depends on the quality of your equipment.Use a high-powered blender, such as aVitamix, or a food processor for best results.

Place the same amount of quick oats as flour needed into the processor. Steel cut oats will take longer to process and will yield more than a 1-to-1 conversion.

Blend the oats until it turns into a fine, powdery flour (about 1 minute). Check to make sure you don’t have any larger flecks of oats, and if so, blend again.

Note about gluten-free oats

Oats and oat flour are gluten free if made with certified gluten free oats. Although oats are naturally gluten free, they are typically processed on equipment shared with wheat products. Certified gluten free means it’s guaranteed to not be cross-contaminated.

Some people with celiac disease or gluten intolerance, though, are still sensitive to oats, whether they are certified GF or not. If making these for a friend or family member, you may want to double check first.

substituting store bought oat flour

If you’d like to use ready-made oat flour instead of grinding your own, you will need 2 2/3 cups or 240 grams.

Do I have to chill the dough?

When making this recipe, I tested chilling the dough and not chilling the dough before baking. There was no measurable difference with spreading, taste, or texture, so save yourself an extra step and time.

If you don’t wish to bake the cookies right away, you can chill the dough up to 24 hours before baking.

expert tips and tricks

• If the cookies spread too much the butter could have been too soft or warm. If that is the case, you can always chill the dough before scooping and baking.
• Another spreading issue could arise from too little or too much oat flour. You will need 240 grams or 2 ⅔ cup measured oat flour.
• Also be sure the homemade oat flour is very fine and powdery. If it is not ground fine enough, the cookies will still taste good, but will be more round than flat.

storing and freezing Cookies

Oat flour cookies are best within a day or two of baking. They loss moisture faster than traditional chocolate chip cookies, so do not make them too far in advance.

Store cooled cookies in an airtight container at room temperature. For storing longer than two days I recommend freezing cooled cookies up to 3 months.

You may also portion out the cookie dough on a baking sheet and freeze until firm. Transfer the frozen cookie dough into an airtight container, or freezer bag, and freeze up to 3 months.

When ready to bake, take your frozen cookies directly from the freezer to bake on ungreased cookie sheets. You may need to add 1-2 minutes to the baking time.

dairy free / vegan adaptation

Although I personally haven’t tried it with this recipe, readers have had success replacing the egg with a flax egg. Based on that, I believe it would work with these cookies as well, especially since it’s only one egg.

The butter can also be replaced with an equal amount of vegan / dairy free substitute, such as Earth Balance vegan buttery sticks.
