Do you have a ton of cupcakes to frost? Several cakes to decorate? Say no more! This mega-batch of icing easily decorated 8 dozen cupcakes, with a bit to spare. It stores well in the fridge for a couple of weeks, or you could freeze the leftovers (thaw in the fridge) for next time.
1 cup hard margarine, softened
1 bag (kg) confectioner's (icing) sugar
1/2 cup milk
1 teaspoon vanilla
Beat all ingredients together until smooth. Store in an airtight container.
