Lemon-Cream Cheese Frosting

"Today is Labor Day, and where we are in New Jersey, the rain is coming down in sheets:( Not the best way to bid farewell to summer; but we moved the party indoors:) My sister, sister-in-law, future sister-in-law, and mother are all gathered around the computer, posting lots of recipes, eating (of course!), and enjoying the inevitable "girl talk." All of our men are out on a "food run," and the kids are napping (yay!). But anyway, my sister came over with lemon cupcakes frosted with this sensational frosting (she had to wrap the platter in foil so her husband couldn't grab any away without her knowing!); and the girls are doing quite a job on them now! And don't worry, we've seized control and hid the cupcakes from the men:)!..."
