I used this recipe for mint chocolate chip cookies and only played with it a little. Instead of chocolate mint chips (which are divine by the way) I used a chopped up mint Theo bar. The Theo bar was a little less minty than mint U.F.O.s (which is of course the name of the mint chocolate chips that you can buy at Trader Joe's) would have been, but still fantastic. The only other addition I made was about a tbs of applesauce for a moister dough.
My daughter and I made these together and we had so much fun. As you can see from the picture, I barely had time to get my camera out before the cookies started disappearing right off the pan. They are very chocolaty, and very tasty, I doubt anyone would guess they were vegan. More importantly though, I think they would be enjoyed by anyone who tried them...........except for chocolate haters........but, you know, there's something wrong with those people anyway. ;)
