Instructions
- Step 1: Preheat oven to 350°F and line two baking sheets with parchment paper. In a medium bowl, whisk together 1 1/2 cups gluten-free rolled oats, 1 cup gluten-free all-purpose flour, and 1/2 tsp baking soda.
- Step 2: In a large mixing bowl, beat 1/2 cup softened unsalted butter with 3/4 cup packed brown sugar and 1/4 cup granulated sugar using an electric mixer on medium speed until light and fluffy, about 2 minutes.
- Step 3: Add 1 large egg and 1 tsp vanilla extract to the butter mixture, mixing until combined.
- Step 4: Gradually add the dry oat and flour mixture to the wet ingredients, mixing on low speed until just combined.
- Step 5: Fold in 1 cup semi-sweet chocolate chips evenly using a spatula.
- Step 6: Scoop dough by 1/4 cupfuls onto prepared baking sheets, spacing them about 2 inches apart.
- Step 7: Bake for 12-14 minutes until cookies are golden around the edges but still soft in the center. Let cool on baking sheets for 5 minutes before transferring to a wire rack to cool completely.
