Notes
Store frosting in an airtight container in the refrigerator for up to 5 days, or freeze for up to 6 months. Bring to cool room temperature before spreading or piping.To make the frosting stiffer, add an additional 1 cup (113g) of sifted confectioners' sugar. about 4 1/2 cups, enough for a 2-layer cake or 24 to 30 cupcakesNever frost a warm cake: the frosting will sink in, or the cake will tear. Chilling or freezing cakes or layers for 30 to 45 minutes before frosting will make the job go much easier. See our online class cake decorating class for pointers.
