Preheat your oven to 350°F (175°C).

Line a baking sheet with parchment paper.

In a mixing bowl, combine the gluten-free flour, baking powder, baking soda, and salt.

In another bowl, beat the softened butter, granulated sugar, and brown sugar until light and fluffy.

Mix in the egg and vanilla extract until fully incorporated.

Gradually add the dry mixture to the wet mixture, mixing until just combined.

In a small bowl, combine the granulated sugar and cinnamon for rolling.

Scoop the dough, roll it into balls, then coat them in the cinnamon-sugar mixture.

Place the dough balls on the prepared baking sheet, spaced apart.

Bake for 8-10 minutes until the edges are set but the centers are still soft.

Let them cool on the baking sheet for a few minutes.
