01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together gluten-free flour, baking soda, baking powder, and fine sea salt until well blended.
03 - In a large bowl, cream the softened butter, maple syrup, and brown sugar until light and fluffy, approximately 2 minutes.
04 - Beat in the egg and vanilla extract until fully incorporated and smooth.
05 - Gradually add the dry ingredients to the wet ingredients, mixing just until the flour disappears. Do not overmix.
06 - Gently fold in the chocolate chips until evenly distributed throughout the dough.
07 - Scoop tablespoon-sized balls of dough onto the prepared baking sheets, spacing 2 inches apart to allow for spreading.
08 - Sprinkle each cookie with a small pinch of flaky sea salt for finishing.
09 - Bake for 11 to 13 minutes, until edges are golden brown but centers remain soft and slightly underdone.
10 - Let cookies rest on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
