Stack of Gluten-Free Oatmeal Cookies.

Easy Gluten-Free Oatmeal Cookies

Thick and chewy gluten-free oatmeal cookies are so easy-to-make. This one-bowl recipe is loaded with gluten-free oats, chocolate chips (or raisins, it's up to you!), and just a hint of cinnamon. 

Prep Time 10 minutes
Cook Time 12 minutes
Servings 23 cookies

Ingredients

  • 1/2 cup butter, melted and cooled slightly (4 ounces/ 113 grams)
  • 3/4 cups firmly packed brown sugar, see note (6 ounces/ 170 grams)
  • 1 large egg (about 2 ounces/ 57 grams, out of shell)
  • 1 teaspoon vanilla extract
  • 1 cup gluten-free flour, see note (5 1/4 ounces/ 150 grams)
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 1/2 cups gluten-free quick or old fashioned oats, uncooked (5 1/4 ounces/ 148 grams)
  • 1 cup chocolate chips OR 1 cup raisins (about 6 ounces/ 170 grams)

Instructions

  1. Preheat oven. Adjust oven rack to middle position and heat oven to 350 degrees Line two baking sheets with parchment paper.

  2. Make the dough. Stir together melted butter and brown sugar until smooth. Add egg and vanilla extract. Mix until smooth. The mixture will look like caramel sauce. Add the gluten-free flour, cinnamon, baking soda, and salt. Sir until you don't see any streaks of flour. Add the oats and chocolate chips or raisins. Mix until combined.

  3. Scoop and Bake. Drop dough, about two tablespoons each, onto one of the prepared baking sheets. Space dough about one inch apart. These don't spread much. Bake until set, about 12 minutes.

  4. Cool. Remove the pan from the oven and allow the cookies to cool on the pan for minutes. (While they cook, bake the remaining dough on the second baking sheet.) Transfer cookies to a wire rack and allow to cool completely.

  5. Store. Keep the cookies covered on the counter for up to four days or freeze for up to three months. To freeze cookies: place in a freezer container and separate layers with a piece of wax or parchment paper. Thaw overnight on the counter.

Recipe Notes

Ingredient Notes

Gluten-Free Flour: This recipe was developed with Bob's Red Mill's 1:1 Gluten-free Baking flour. Using a different gluten-free flour might affect the texture of the cookies. 

Brown Sugar: Use light or dark brown sugar. Dark brown sugar gives the cookies a more pronounced molasses flavor.
