01 - Line a 9x13 inch baking sheet with parchment paper, ensuring complete coverage to prevent sticking.
02 - Place white chocolate in a microwave-safe bowl. Microwave in 30-second intervals, stirring thoroughly between each burst, until completely smooth and melted. Alternatively, melt over a double boiler using simmering water.
03 - Let melted chocolate cool for 2 minutes, then gently fold in the mini marshmallows until evenly distributed throughout the chocolate.
04 - Pour the chocolate-marshmallow mixture onto the prepared baking sheet. Use a spatula to spread into an even layer approximately ½ inch thick.
05 - Sprinkle chopped candy eggs and pastel sprinkles generously over the surface. Press lightly with the spatula to embed toppings into the chocolate.
06 - Refrigerate for at least 1 hour until the bark is completely firm and set throughout.
07 - Break or cut into irregular pieces and arrange on a serving platter.
