In a mixing bowl, combine the gluten-free flour, brown sugar, granulated sugar, and salt. Whisk these dry ingredients together until fully mixed.

Add the softened butter and vanilla extract to the dry mixture. Using a hand mixer or spatula, mix until it becomes a creamy dough.

If the dough is too crumbly, drizzle in the milk one tablespoon at a time until the desired consistency is reached. Aim for a dough that holds together but isn’t overly sticky.

Gently fold in the chocolate chips or your chosen mix-ins until evenly distributed.

Grab a spoon and enjoy a taste test—just remember, you can eat as much as you want since it’s just cookie dough!
