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 it into an even layer approximately ½ inch thick.
05 - Sprinkle the chopped candy eggs and pastel sprinkles evenly over the surface. Press lightly with your fingertips to ensure they adhere to the chocolate.
06 - Refrigerate the bark for at least 1 hour, or until completely firm and set throughout.
07 - Break or cut the bark into irregular pieces. Store in an airtight container at room temperature for up to one week.
