To a large bowl add dairy free butter and light brown sugar and whisk with an electric whisk until creamy.
Add the egg and continue to whisk. Add the vanilla extract and whisk again.
Add the gluten free flour, xanthan gum, ground ginger, ground cinnamon, bicarbonate of soda, baking powder and salt. Mix well until fully combined,
Mix in the dairy free white chocolate chips. Place into the fridge for atleast an hour to chill.
Whilst the dough chills preheat your oven to 180°C and line 3 large baking trays with baking paper.
Take your dough out of the fridge and roll into 12 equal sized balls.
Spread the cookie balls out on the baking trays. The cookies will spread as they cook, so ensure to leave plenty of room around each cookie.
Bake for 12-14 minutes, remove from the oven and leave to cool. The cookies will continue to cook and firm up once they are out the oven and cool.
