What you will need to make the shortbread :
8oz plain flour
4oz caster sugar
Mix together the sugar and butter, add flour bit by bit and crumble . Then blend until its in a thick dough. If it won't blind together use a touch of water. Roll it out with a rolling pin and add to a baking tray. I used the top of casserole lid for mine then just poked the to with a fork.
Cook on gas mark 4 for 15 minutes until golden. Wait to cool then cut.. We seemed to have used self raising flour instead of plain so it ended up more of a shortbread cake, it went well with a bit if custard and both kids said it was delicious. That's what happens when a three year old is helping you and you don't pay attention hehehe
