Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.
Beat in the egg and vanilla extract until well combined.
In a separate bowl, whisk together the gluten-free flour, baking soda, baking powder, and salt.
Slowly add the dry ingredients to the wet ingredients, mixing until just combined.
Fold in the chocolate chips.
Drop tablespoon-sized balls of dough onto the prepared baking sheet, spacing them about 2 inches apart.
Bake for 10-12 minutes, or until the edges are golden and the centers are set.
Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
