Place white & dark chocolate (separately) in microwave-safe bowls, & melt chocolate in the microwave in 45-second increments until melted & smooth.

Pour dark melted chocolate, alternating with white at the center of the parchment paper. It will spread & naturally take on a circular shape. Use a small spatula to spread chocolate while spinning the turntable. Feel free to use a baking tray & spread the chocolate into rectangular or square shapes. 

Using a toothpick, swirl chocolate to make a marbling effect. 

Arrange pretzels, cranberries, shaved almonds, & sprinkles on top of melted chocolate 

Place in the freezer for 20 minutes until solid. Then break the bark into small pieces & dive in!
