Line a baking sheet with parchment. Using a serrated knife, finely chop the white chocolate. In a medium microwave-safe bowl, microwave white chocolate in 30 second intervals for about 2 minutes, stirring in between, until melted and smooth.
Meanwhile, if desired, roughly chop any larger pieces of Easter candy. To melted white chocolate, stir in 1 tablespoon sprinkles and a pinch of salt. Pour melted white chocolate onto parchment, using a spatula to spread into a thin even layer.
Scatter remaining 1 tablespoon sprinkles on white chocolate and then scatter candy on top, pressing any larger pieces gently to stick. Refrigerate until set, then break into pieces.
