2 tsp grated lemon rind
1 Tbsp lemon juice

Instructions
Preheat oven to 160°C. Line 2 oven trays with baking paper, In a mixer beat the 125g butter till pale and creamy, Add the 1/4 cup Icing sugar, flour, custard powder and mix with spoon till well combined, Make balls with the mixture and using a fork press it into each ball leaving a mark, Bake for approx 10mins and check every 5mins after that "they don't take long" Set aside to cool while you make the filling.

Filling: Beat the extra butter and icing sugar in a bowl until light and fluffy. Add the lemon rind and juice and beat until combined, Put a dollop on the flat side of half the biscuits and sandwich them together with the rest.    Enjoy!  =)
