I love silicone molds and luster dust. You can make things with fondant that look completely real. Like the 50 Sea Shell cupcakes I made for a bridal shower.
Just add the fondant to the mold, remove the excess and pop it out. They look pretty good that way, but when you add the dust they become as real as you can imagine. And I have seen many, many sea shells in my life. Especially since my boys love to collect them.
The flavors are Chocolate with Vanilla Buttercream, Vanilla with Chocolate Buttercream, and Strawberry with Vanilla Buttercream.
The top view of some of the cupcakes. It is hard to see the colors from these pictures so I will have to show you some close ups of the shells.
