Costco Tuxedo cake is made with rich dark layers of chocolate cake and filled with layers of creamy white chocolate mousse and chocolate mousse with brownie pieces. The cake is topped with a layer of dark chocolate ganache and chocolate sticks (curls). This is one of Costco’s more impressive looking cakes – it looks far more expensive than it is! A comparable cake from a local bakery would easily cost 3x or more. We recommend this Costco dessert, it is a crowd pleaser for adults and kids alike.
