industries as a sprinkle on top of baked goods. The large crystals reflect light and give the product a sparkling appearance.

•DO-AHEAD TIP: Cake can be made up to 2 days ahead. Wrap in plastic and store at room temperature.
Additional Info
Tip: When baking a cake, it is necessary to butter and flour the pan before filling to keep the cake from sticking. Melted butter is easy to spread and gets into
all those nooks and crannies in a Bundt pan. Melt the butter in a butter warmer or microwave and brush it onto the sides of the pan with a pastry brush.
Then dust the pan with flour,
tapping out the excess.
