GF Lemon And White Chocolate Cookies

150 g softened butter
1/4 cup brown sugar
1/3 cup caster sugar
1 egg yolk
1 tsp vanilla essence
1 1/2 cups flour (2 parts rice, 1 part corn, 1 part tapioca plus 1 tsp guar gum)
1 1/2 tsp baking powder
~100 g white chocolate, chopped into chunks
rind and juice of 1 lemon

• Mix butter, sugar and egg together until smooth
• Add vanilla and mix through
• Add flours and baking paper, mix until combined
• Stir in chocolate and lemon rind and juice 
• Roll in to balls and place on a tray lined with baking paper
• Bake 10-15 min at 180°C until lightly browned

Variations:  To make a lactose-free version, use dark chocolate and margarine.  

The recipe works with just rice flour - use only 1 tsp baking powder, and add about a tablespoon of water

This is a very versatile recipe, so play around with different types of chocolate, with or without lemon.  I particularly like using a mix of white and milk chocolates, with no lemon.
