Method

1. Cream the butter and sugar together very thoroughly until light and fluffy. Add the flour and custard powder and mix to form a firm dough.

2. Break off small pieces, the size of a walnut, and roll into a ball with your hands. Place on the cold plain shelf lined with Bake-O-Glide. Flatten slightly and mark the holes of a ‘button’ in the centre of each biscuit.

3. Slide the plain shelf onto the third set of runners in the Baking Oven. Cook for 10-15 minutes until lightly golden.

Notes - Cool on a wire rack.
