Preheat your oven to 350°F (175°C).
In a medium bowl, combine the gluten-free rolled oats, gluten-free all-purpose flour, baking soda, and salt. Mix thoroughly.
In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy, about 2-3 minutes. Add the egg and vanilla extract, mixing until well combined.
Gradually add the dry ingredients to the wet ingredients, stirring gently until just combined.
Fold in the chocolate chips until evenly distributed.
Drop balls of dough onto the prepared baking sheet, spacing them about 2 inches apart.
Bake for 10-12 minutes until the edges are lightly golden and the centers remain soft. Let cool on the baking sheet for 5 minutes before transferring to a wire rack.
