Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
In a mixing bowl, cream together the butter, brown sugar, and granulated sugar until smooth.
Beat in the egg and vanilla extract until fluffy.
In another bowl, whisk together the gluten-free flour, baking soda, and salt.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Fold in the chocolate chips.
Drop spoonfuls of dough onto the prepared baking sheet.
Bake for 10-12 minutes, or until the edges are golden brown.
Allow cookies to cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
