I made these along with the vegan cookies 'n cream cupcakes and the lemon meringue cupcakes. The frosting was amazing. My roommates and I ended up eating the leftover frosting on the remaining Oreos. Yum! I also really liked the cupcake recipe, but I might have just used it as a muffin and not bothered to frost it.
Recipe from here which comes from Vegan Cupcakes Take Over the World. I've been really impressed with all the recipes in this book - I might have to go out an buy it!
