100 Days of Real Food is one of my favorite sites and her recipes turn out so good. I haven't tried her cupcake recipe, but she has one:
Hey! Thanks for the referral! This is still my customers' favorite icing and I really enjoy working with it. It can be left out for a while, but it can be refrigerated or frozen. Just re-whip and it should be good to go!
There USED to be a program you could buy (2 actually - Make the Cut and Sure Cuts A Lot) but a couple of years ago both companies were sued by Provocraft and you can still buy them, but they no longer work with the Cricut. I use SCAL, and it makes my Cricut SO useful. I would never use it if I had to rely on those horrible cartridges!
