Place the dark chocolate in a microwave safe bowl. Heat in the microwave for 20 seconds. Stir, and repeat the heating process until the chocolate is mostly melted. Stir until smooth.
Next, pour the dark chocolate onto the prepared pan. Use a rubber spatula to spread it in an even layer. Set the chocolate aside until set.
When the bottom dark chocolate has hardened, melt the white chocolate in a separate bowl. Heat for 20 seconds, stir, and repeat until melted.
Pour the white chocolate over the dark chocolate. Carefully spread evenly.
While the top layer of chocolate is still soft, sprinkle the cashews, cranberries, and orange peel over the top. Gently press the toppings into the chocolate.
Set aside until firm. Break or cut into pieces and serve.
Notes
Be careful to NOT overheat the chocolate. If you over heat it, it can seize up and become unworkable. Slowly heat it a few seconds at a time for the best results.TIP: If you are in a super hurry, you can pop the chocolate in the fridge for a few minutes to speed up the setting process.
