Mmm. Delicious baked goods.
200g butter, creamed with 3/4 cup icing sugar; then add 1 cup cornflour, 1 cup ordinary flour and a 1/2 teaspoon of baking powder, and mix to combine.
When the flour is being mixed in, it seems to get a little bit clumpy, then it gets all grainy; but keep on mixing, because it’ll come back together again.
Roll into little balls, squish with a fork, and cook for 20 minutes at 180C. Once cool, smoosh two biscuits together with icing.
