Fluted brioche molds, traditionally used to bake the rich and buttery French yeast bread known as brioche, are also perfect for baking fanciful cakes. Sold in a variety of sizes, we chose the 8-inch brioche molds for our cakes. Because we used nonstick molds with a dark outer surface, we covered them with aluminum foil. The shiny side of the foil reflects the heat away from the sides of the mold for a lighter, bright red crust. You'll find baking instructions included on the packaging with most pans.
