This is a copycat of the William Sonoma Bark that costs $22 a lb. I have never tried their version, but when my mom told me she liked it, I went on a search to find the recipe. Make sure to buy white chocolate chips that contain cocoa butter to get a smooth melt- otherwise, you will end up with clumpy chocolate. Use good quality chocolate chips (belgian, semi-sweet, or bittersweet) for the best results.This recipe is so simple and delicious my only hope is that I'm able to save a piece for my mom.
