Pre heat the oven to 180 degrees
Whisk 200g unsalted butter and 200g caster sugar in a bowl until light and fluffy
Add 4 eggs and continue to whisk
Add 200g self raising flour and 100ml of vanilla milkshake can continue to whisk until all ingredients are mixed in
Pour the mixture into a greased oven tin and cook for 30 minutes until golden
