This mushroom dessert is only partially an illusion. The mousse filling the mushrooms is actually flavored with candy cap mushrooms, which taste strongly of maple syrup with just a hint of an earthy note that is absolutely delicious! The mousse is enrobed in a crisp white chocolate shell. A cherry red mirror glaze and finely grated white chocolate finishes the mushroom cap look while a light dusting of cocoa powder finishes the stems. The overall illusion is complete with a crumbled black cocoa cupcake soil, cocoa rocks, and green brown butter dust moss. Though there are multiple components here, they can all be prepared in advance. Whole assembled mushrooms and be made and frozen for up to 2 months. Then just glaze before serving. Likewise, the cake, rocks, and moss can be made days ahead and refrigerated, or frozen for up to 2 months.
