Ingredients
  

For the Cookies
  • 1.5 cups 1:1 Gluten-Free All-Purpose Flour ensure it contains xanthan gum
  • 3 cups Certified Gluten-Free Rolled Oats
  • 1 teaspoon Baking Soda
  • 1 teaspoon Ground Cinnamon
  • 0.5 teaspoon Salt
  • 1 cup Unsalted Butter softened to room temperature
  • 1 cup Light Brown Sugar packed
  • 0.5 cup Granulated Sugar
  • 1 Large Egg at room temperature
  • 2 teaspoons Pure Vanilla Extract

Equipment

  • 2 Baking Sheets
  • 1 Electric mixer (hand or stand)
  • 2 Mixing Bowls

Method
 

  1. In a medium bowl, whisk together the 1:1 gluten-free flour, certified gluten-free oats, baking soda, cinnamon, and salt. Set aside.
  2. In a large bowl with an electric mixer, beat the softened butter, light brown sugar, and granulated sugar on medium-high until light and fluffy, about 2-3 minutes.
  3. Beat in the egg and vanilla extract on high speed for 1 minute until fully combined, scraping down the sides of the bowl as needed.
  4. On low speed, gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
  5. Cover the bowl and refrigerate for at least 30 minutes.
  6. Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper.
  7. Scoop rounded tablespoons of dough onto the prepared baking sheets, about 2 inches apart.
  8. Bake for 10-12 minutes, until edges are golden brown. Let cool on the baking sheet for 5 minutes before moving to a wire rack to cool completely.

Notes

Measure Flour Correctly: Spoon flour into the measuring cup and level it off to avoid dense cookies.
Don't Skip Chilling: Chilling the dough is essential for a chewy texture and prevents the cookies from spreading too much.
Variations: Feel free to add 1 cup of chocolate chips or 3/4 cup of raisins for a fun twist.
