Rock Cakes

Preheat oven to 180C/350F/Gas 4 and line a baking tray with baking parchment. Mix the flour, sugar and baking powder in a bowl and rub in the cubed butter until the mixture looks like breadcrumbs, then mix in the dried fruit. In a clean bowl, beat the egg and milk together with the vanilla extract. Add the egg mixture to the dry ingredients and stir with a spoon until the mixture just comes together as a thick, lumpy dough. Add a teaspoon more milk if you really need it to make the mixture stick together. Place golfball-sized spoons of the mixture onto the prepared baking tray. Leave space between them as they will flatten and spread out to double their size during baking. Bake for 15-20 minutes, until golden-brown. Remove from the oven, allow to cool for a couple of minutes then turn them out onto a wire rack to cool.
