Peppermint Bark
16 oz. bittersweet chocolate, coarsely chopped
4 oz. white chocolate coarsely chopped
4 6-in candy canes, chopped
1. Line a 15 1/2 x 10 1/2 jelly roll pan with nonstick foil or parchment paper, leaving a 2-in. overhang on 2 sides. In the microwave safe bowl, melt the bittersweet chocolate on high, stirring every 20 seconds, until smooth. Spread it into the prepared pan.
2. In a microwave-safe bowl, melt the white chocolate on high, stirring every 20 seconds, until smooth. Drop small spoonfuls onto the bittersweet chocolate and, using a skewer, swirl the white chocolate through the dark.
3. Let the chocolate set for 5 minutes. Sprinkle with the candy canes, then refrigerate until set, about 30 minutes. Break into pieces before serving.
Very easy !
