A Parisian favorite. Grand Marnier Cake is a decadent and sophisticated dessert perfect for special occasions or a delicious treat to enjoy with coffee or tea. It is a favorite among those who appreciate the rich, complex flavors of the premium liquor, the satisfying indulgence of a delicious cake, and the citrus marmalade pillowed in our signature swiss buttercream. The true pièce de résistance of cakes.
