AThe recipe I'm using calls for 2 sticks of butter, but I don't want to use that much! The recipe uses a 1:1 ratio so I think 1 stick should be enough..but maybe not. I'll use the rose swirl (inside then swirling out) so I probably won't use that much butter. Help?

Well, the cold-process BC recipe that's been on the back of the C&H powdered sugar box since before most of us were born easily covers a 9x13 single-layer sheet cake, or a 9" round layer cake, with frosting to spare, and it only uses one stick. Of course, it all depends on how much frosting you put on a cupcake.

AI pipe my frosting and have to use 2 sticks for 12 cupcakes!

One batch of frosting should be enough to cover 24 cupcakes!! But these days, the way people pipe these high piles of frosting on, maybe not.. Make 2 batches just in case. You can always freeze it !
