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, melt over a double boiler using a heatproof bowl over simmering water.
03 - Let the melted chocolate cool for approximately 2 minutes to prevent marshmallows from melting completely. Gently fold in the pastel 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 1/2 inch thick.
05 - Sprinkle the chopped candy eggs and pastel sprinkles evenly over the surface. Press lightly with clean hands or a spatula to ensure toppings adhere to the chocolate.
06 - Refrigerate the bark for at least 1 hour or until completely firm and set throughout.
07 - Break the bark into irregular pieces or cut into squares using a sharp knife. Serve immediately or store in an airtight container.
