Melt: place chocolate chips or chopped chocolate bars into a microwave-safe or heat-proof bowl and heat in the microwave in 30-second intervals. Or the heat-proof bowl can be placed over a saucepan with simmering water.
Spread: cover a rimmed baking sheet with parchment paper and using a rubber spatula spread the melted chocolate in an even layer.
Sprinkle: layer the toppings onto the chocolate and gently press them in.
Cool: allow the bark to cool at room temperature for 2 to 4 hours or place in the refrigerator for 15 to 30 minutes.
Break: using your hand break the firmed up bark into small pieces.
