Create your own mini farm by adding our cow and pig cakes to your barnyard party.
For the basic shape, set a dome cake upside down in the center of a round cake and secure with icing.

Cut one cupcake in half and place it for the ears, then arrange two more cupcakes as legs.
Frost the cakes (except for a triangular face area), the outsides of the ears, and the top halves of the hooves with the white icing, then cover with mini marshmallows.
Use a pastry bag (or a plastic bag with one corner cut off) to pipe small dollops of chocolate icing onto the face, bottom halves of the hooves, and centers of the ears. Decorate as shown.
