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 fully melted. 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 pastel mini marshmallows until evenly distributed throughout the chocolate.
04 - Pour chocolate-marshmallow mixture onto the prepared baking sheet. Use a spatula to spread evenly into a layer approximately ½ inch thick, ensuring uniform thickness across the entire surface.
05 - Sprinkle chopped candy eggs and pastel sprinkles generously over the surface. Press lightly with your fingertips to embed decorations into the chocolate so they adhere properly.
06 - Refrigerate the bark for at least 1 hour until completely firm and set. The chocolate should be hard to the touch and break cleanly when chilled through.
07 - Break bark into irregular pieces or cut into rectangles using a sharp knife. Serve immediately or store in an airtight container at room temperature for up to one week.
