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 glossy. Alternatively, melt over a double boiler using simmering water.
03 - Let melted chocolate cool for 2 minutes to prevent marshmallows from melting completely. Gently fold in mini marshmallows until evenly distributed.
04 - Pour chocolate-marshmallow mixture onto prepared baking sheet. Use spatula to spread into even layer approximately 1/2 inch thick.
05 - Sprinkle chopped candy eggs and pastel sprinkles over surface. Press lightly with spatula to ensure toppings adhere to chocolate.
06 - Refrigerate for minimum 1 hour until bark is completely firm and set throughout.
07 - Break or cut bark into irregular pieces. Serve immediately or store in airtight container.
