In a bowl whisk the gluten-free flour, gluten-free baking powder and salt until they are combined.
In a large bowl whisk the melted butter, brown sugar and granulated sugar until they are mixed and creamy.
Gently stir in the beaten eggs.
Add the dry ingredients and stir together with a spatula.
Stir in the chocolate chips and fold into the dough mixture.
Cover the bowl with some tin foil and put into the fridge for at least four hours. Overnight is better.
Take the dough out of the fridge and allow it to reach room temperature.
Preheat the oven to 350 (gas 4). Line 2 baking sheets with baking sheets.
Using a tablespoon scoop the dough onto the baking sheet and space the cookies about 3" apart.
Bake the cookies, rotating the trays until the edges are golden brown. This should take 12-14 minutes.
Transfer to a wire cooling rack.
