Line a cookie sheet with parchment paper or wax paper, set aside.
In a medium microwave-safe bowl, add the chocolate wafers and heat in the microwave on 50% power in 30-second increments, stirring after each 30 seconds, until chocolate has melted and becomes smooth when stirring.
Using an offset spatula spread chocolate on the parchment or wax paper into an even layer, 1/4 inch thick. You should have about an 8 x 12 rectangle of chocolate.
Evenly sprinkle the toppings over the chocolate; set aside to cool on the counter if your house isn't too hot or refrigerate until set hard. Once cooled, transfer the bark to a cutting board and break the bark into pieces by pressing on it with the point of a sharp knife.
