"Naked cake"

When I saw the photo above I assumed it was taken before the cake was finished.  Not so.  Leaving the sides of a cake unfrosted is intentional.

Bakers these days are holding back frosting from wedding cakes for an exposed look that is popular with couples looking for a traditional wedding cake alternative. But is this frosting-free look right for you? These naked cakes will surely convince you.

As these couples will show, there's a naked cake for every celebration. Choose between shaved, striped layers or creative bases (think: pavlova, crêpes, or even cheese), sparsely placed icing or no icing at all, and décor that makes up for whatever frosting is missing. Even better, try new flavors, without the threat of finding a frosting to match. These naked concoctions are chic, sophisticated, and beautiful—not too sweet, but just sweet enough.

A gallery of 44 "naked cakes" is included at this Martha Stewart Weddings link.
