Ingredients & Substitutions

Room temperature butter is key in yielding a buttery flavor. Leave butter out on countertop 1 to 2 hours before baking to naturally soften it. If you forget this step, microwave butter for 7 seconds to slightly soften it. Softened butter creams well with the brown sugar.

Light brown sugar adds the perfect amount of sweetness. Tightly pack brown sugar. If desired, coconut sugar can be substituted.

The egg helps bind the cookie dough together. I haven’t tried to make these cookies Vegan, but my best guess would be to substitute the 1 egg with 1/4 cup applesauce. I’d also add 1/4 cup more of oat flour to offset the moisture.

Vanilla extract adds the classic cookie flavor. Do not forget it!

Oat flour is made from ground up oats. I highly suggest buying oat flour rather than making it. See below for more information.

Baking soda helps these cookies rise while baking.

Dark chocolate chips are my favorite chocolate for cookies. They provide a rich and decadent feel to these oat flour cookies, but use your favorite variety of chocolate chips.

How to Make Oat Flour

Oat flour can be made at home! Simply adds old fashioned rolled oats to a blender or Vitamix and blend until a powdery flour substance is reached. There is a fine line between not quite blending enough and having little pieces of oats in the flour and over blending. For this reason, I recommend buying oat flour pre-made.

One cup of oats yields just slightly less than 1 cup of flour. For this recipe, blend just over 2 cups of oats into oat flour before measuring and using.

Homemade Oat Flour Versus Store Bought

As mentioned above, oat flour can be bought or made. I did not have success with making homemade oat flour. After blending the oats in my Vitamix for 5 minutes, it still wasn’t perfectly powdery or uniform.

I made this same recipe with homemade oat flour and it required almost 3 full cups of homemade oat flour to bake. The first batch with only 2 cups of homemade oat flour turned into pancakes in the oven! For more helpful tips and tricks, check out this Guide to Gluten Free Flours and Gluten Free Baking.

For this reason, I highly recommend buying oat flour. It is sold in most grocery stores in the baking aisle. I bought Gold Medal Oat Flour and was very pleased with it!

Expert Tips & Tricks

Use room temperature butter for best results. It creams nicely with the brown sugar.

Store bought oat flour is much easier to use than homemade oat flour.

Chill dough at least 30 minutes, up to overnight. The longer it chills, the more thick the cookies will become. For the photos in this blog post, the dough chilled for 30 minutes.

Bake until cookies are just set in the middle.

They are fragile and soft after baking. Handle carefully.

  • If you forget to place butter out to soften, microwave butter for 7 seconds to slightly soften it.
  • I have tried this recipe with both homemade oat flour and store bought.  I highly recommend store bought since it is finer and more uniform.  I used Gold Medal Oat Flour.
