Preheat oven to 190 degrees celsius/375 degrees fahrenheit (fan forced) and grease both baking trays.
Sift flour, mixed spice, baking powder and salt into a mixing bowl.
Add butter and rub into sifted dry ingredients with your fingertips, or process in a food processor, until there are no lumps of butter and the mixture resembles fine breadcrumbs.
Stir though sugar and mixed fruit with a blunt knife.
Add egg and milk and stir through with the knife until combined. Add the extra milk, one tablespoon at a time, if necessary so that mixture holds together and has a stiff consistency.
Put heaped tablespoons of mixture onto baking trays, leaving room for spreading. You should have about 12 pieces.
Sprinkle each cake with the extra sugar and place cherry halves on top.
Cook in oven for 15 minutes or until a golden colour.
Once out of the oven, transfer the cakes to a cooling rack.
