01 - Line a 9x13 inch baking sheet with parchment paper to prevent sticking and ensure easy removal once set.
02 - Place white chocolate in a microwave-safe bowl and heat in 30-second intervals, stirring thoroughly between each burst until completely smooth and glossy. Alternatively, melt over a double boiler using simmering water.
03 - Let melted chocolate cool for 2 minutes to prevent marshmallows from melting completely, then gently fold in pastel mini marshmallows until evenly distributed.
04 - Pour chocolate-marshmallow mixture onto prepared baking sheet. Use an offset spatula to spread into an even layer approximately 1/2 inch thick, ensuring uniform thickness.
05 - Immediately sprinkle chopped candy eggs and pastel sprinkles over surface, pressing lightly with fingertips to embed decorations into chocolate.
06 - Refrigerate for at least 1 hour until completely firm and set throughout. The bark should break cleanly when fully chilled.
07 - Break bark into irregular pieces by hand or cut into squares with a sharp knife. Serve immediately or store in airtight container.
