If you're not into peanut butter, or are allergic, try them with some creamy brie and sour cherries. Otherwise, use 100% natural or organic peanut butter for the filling. Dairy-free substitutes can be used in place of butter and milk. Gluten free flour can be substituted for regular self-raising flour if you wish. You will need a rolling pin, baking paper and a cookie cutter or a sharp knife.
