Sno Balls are cream-filled chocolate cakes covered with marshmallow frosting and coconut flakes. They come in packages of two and are sold at many convenience and grocery stores in the United States.
A similar cake produced by Tunnock's, called a "Snowball", is often sold at supermarkets in the United Kingdom; these cakes are typically covered in desiccated coconut, but are typically brown rather than pink, because they may have chocolate on their outside.
