Cream together the icing sugar and butter until soft and well combined.
Stir through the custard powder and the flour. This should form a stiff ball of well combined dough, take care not to overwork the dough, only bring it together.
Line a baking sheet with parchment paper. Take a teaspoon of the dough and roll it into a ball and place it on a baking sheet. Use a fork to gently press down the top of each ball of dough - don't press too hard. Leave sufficient space between each ball to allow the biscuits to spread in the oven.
When done place the custard creams into an oven at 180C/160CFan for 12-15 minutes. Remove from the oven and place the biscuits on a wire rack to cool.
Meanwhile mix together the icing sugar and butter to make the butter icing.
Once the biscuits have cooled spread some butter icing between two biscuits and allow to the icing to set. Store the sandwiched biscuits in an air-tight container.
