01 - Line a 9x13 inch baking sheet with parchment paper to prevent sticking and ensure easy removal.
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, use a double boiler over simmering water.
03 - Let the melted chocolate cool for 2 minutes to prevent marshmallows from melting completely. Gently fold in the mini marshmallows until evenly distributed.
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 ensure toppings adhere to the chocolate.
06 - Refrigerate the bark for at least 1 hour until 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.
