Reese's Pieces Chocolate Bark

Reese's Pieces Chocolate Bark 2 tablespoons Margarine, Divided 1 1/2 cups Milk Chocolate Chips 1 1/2 cups Peanut Butter Baking Chips 1/2 cup Reese's Pieces Line a cookie sheet with parchment paper. Set aside. Take out two small microwave-safe glass bowls. Add 1 tablespoon of shortening to each bowl. Add the milk chocolate to one bowl. Add the peanut butter chips to the other. Place each bowl, one at a time, into the microwave. Heat for 1 minute, then remove and stir. Heat for approximately 30 to 60 seconds more, making sure to stop the microwave every 15 seconds to check it and stir until it's smooth. Now grab two large spoons and start to drizzle each flavour on the parchment randomly. You just play with your food at this point. Have fun with it. Once it's started to fill in all the gaps give the cookie sheet a tap on the counter. Then take an offset spatula, or even a knife and start running it through the chocolate and peanut butter to make any pattern you like. Toss the Reese's Pieces on top randomly. Pop the cookie sheet in the fridge for about 30 minutes. Remove and break into pieces.
