For the June birthday boy in the family, we bought a Tuxedo cake from the Richmond Costco.
The Tuxedo Cake is in a long rectangular shape instead of the more traditional round or more squarish shape.
Costco Tuxedo cake is made of a base of chocolate cake top with chocolate mousse follow by a layer of white color frosting (perhaps with cream cheese) and another layer of chocolate cake. Finally it is topped with chocolate ganache.
The Tuxedo cake is garnished with a white chocolate roll and some crunchy little white and chocolate balls which the birthday boy likes.
