Made with much less confectioners’ sugar than the usual cream cheese frosting, it’s sturdy, dependable and not too sweet - just right for a child’s birthday party or to ice three-dozen cupcakes for a bake sale. While it’s not quite as silky as a buttercream based on beaten eggs and sugar syrup, it’s much, much less persnickety to make and it holds up well without refrigeration for several hours before it starts getting soft. Plus, the cream cheese makes it incredibly creamy while adding a tangy bite that helps tone down the sweetness of the confectioners’ sugar. To make lemon cream cheese buttercream (which tastes a little like a cheesecake), substitute one tablespoon lemon juice for the vanilla and add a teaspoon of grated lemon zest to the frosting.
