Quick answer
Costco custom cakes come in two flavors: white cake with vanilla cheesecake mousse and chocolate cake with chocolate mousse, both with buttercream icing. Ready-made cakes add more flavors, like the Tuxedo Chocolate Mousse Cake, New York cheesecake, Caramel Tres Leches, carrot, and fall pumpkin cakes. Flavors can’t be mixed on custom cakes.
