In a microwave-safe bowl, melt the chocolate chips in 20-second intervals, stirring in between until melted.
Spoon onto the baking sheet and spread to make a thin layer. Place in the fridge for 5-6 minutes to set temporarily.
Meanwhile, melt the white chocolate in 20-second intervals, stirring in between until melted.
Remove the baking sheet with the slightly hardened chocolate from the fridge, and spoon the white chocolate over top. Spread in a thin layer, being careful to keep it thick enough that the chocolate does not show through.
Working quickly, top the bark with Easter candy and sprinkles all over the top of the white chocolate layer.
Refrigerate until set, about 30 minutes. Remove and peel from the wax paper, then break the bark into small pieces. Store in the fridge in an airtight container.
