Baking tins should be greased and lined to prevent the dough from sticking to the sides during cooking. It makes life much easier when it comes to turning the finished item out of the tin.
-Using a pastry brush, brush the base and sides of the cake tins all over with melted butter or oil.
-Cut circles of baking parchment that are just slightly smaller than the diameter of the baking tins. Press one circle of paper into each of the tins.
