These are fantastic! I used half bittersweet and half semisweet (Ghirardelli chips) and only about half the amount of peppermints. I also didn't use the white chocolate because I thought I had some in bar form but only had chips which as it turns out do not melt very well. I didn't find the cookies were lacking for not having the white chocolate except maybe in the presentation - they still tasted great! Actually I couldn't keep out of them! :) Thanks for sharing!
