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. Using a spatula, 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 ensure decorations adhere to 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. Store in an airtight container at room temperature for up to one week.
