Whip all ingredients until you get a very firm consistency.*
Use immediately or store in the fridge for up to 1 day. Keep all frosted baked goods refrigerated.
One recipe makes enough frosting for a two-tier, 9-inch diameter, naked layer cake. To coat the outside of the cake as well, double the recipe.*Pay close attention when whipping this frosting. If it's underwhipped, it will not hold its shape. If it's overwhipped, it will become grainy. The frosting is perfect when it starts to reach very stiff peaks.
