All Custom Cakes Must Be Ordered At Least 24 Hours In Advance. Creating a gorgeous display of delicate flowers and colorful butterflies, our Las Vegas bakery Sweet Dreams design is styled for the truly feminine sixteen-year-old. This sweet sixteen cake features two white-frosted layers bordered with delicate pink latticework. A cascading mix of pastel-colored flowers runs along one side from top to bottom. In lieu of a sweet sixteen cake topper, fondant flowers featuring the letters in the birthday girl's name are spread across the top of the cake. This is one of the prettiest selections of all of our Las Vegas sweet sixteen cake designs.
