Wilton Two-Colour Cupcake Insert, 3 pcs Making two-coloured cupcakes often involves a lot of mess. With this mould, it has never been easier. All you have to do is place the mould in a cupcake/muffin tin, fill the inside with one colour of batter and the outside with another colour. Once you remove the mould, the batter will fall into place and the cakes are ready to go in the oven. Please note: the mould is not suitable for use in the oven!
