Cream the butter and the sugar together until pale. Use an electric hand mixer if possible.
Add 25g Maui sheep milk powder
Beat in eggs
Sift over the flour and fold in using a large metal spoon
The mixture should be of a dropping consistency; if it is not, add a little water
Divide the mixture between the cake tins and gently spread out with a spatula. Bake for 20-25 minutes until an inserted skewer comes out clean. Allow to stand for 5 minutes before turning on to a wire rack to cool.
Sandwich the cakes together with jam, lemon curd or whipped cream and berries or just enjoy on its own.
