Taken from my new book..

Mix 175g flour, 3tbsp custard powder and 1tsp baking powder. Rub in 100g butter. Whisk an egg with 1tbsp milk and gradually add to the mix forming a dough. Add more milk if it’s not enough. Knead to a smooth dough and rest for 20 mins.

Preheat your oven to 180C and line some baking trays

Roll out the dough and cut into shapes.. remember they’ll be sandwiched together so you need an even number. You can roll them pretty thin, as I discovered, they rise a lot.

Bake for 15 mintues and leave to cool.

Cream together 100g icing sugar, 1tbsp custard powder and 50g butter, add milk if necessary. Use to sandwich the biscuits together.

Et voila! Custard Creams… absolutely wonderful 😀
