The icing was just as easy and really yummy! The recipe tells you to start with 5 cups of sifted powdered sugar and then add more to get your desired consistency. I think I ended up using just under 6 cups. The cake recipe made 12 cupcakes but the icing recipe (depending on how much icing you like on each cupcake) could have iced more than 12 cupcakes, probably about 18 cupcakes. Overall these cupcakes were delicious! It didn't taste exactly like boxed funfetti cake but I think it was better. It had more of a buttery flavor.
