This delicious cream cheese frosting recipe came with the Sprinkles Pumpkin Cupcake mix that I purchased from the Williams-Sonoma catalogue, and baked over the holidays this year. Sprinkles cupcakes have been featured on Oprah as one of her favorite things and, having eaten more than a few while I was in California last year, I would definitely have to agree! I have made other cream cheese frostings before but this one was the best in my opinion. Although it is featured with the pumpkin cupcake, I think it would pair equally well with a spice cake. This recipe generated enough to very generously cover 12 cupcakes. Use the best cream cheese, butter, cinnamon, and vanilla you have. I hope you enjoy it as much we did!
