01 - Line a 9x13 inch baking sheet with parchment paper to prevent sticking and ensure easy removal of the bark once set.
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, use a double boiler over simmering water.
03 - Let melted chocolate cool for approximately 2 minutes to prevent marshmallows from melting completely. Gently fold in mini marshmallows until evenly distributed throughout the chocolate base.
04 - Pour chocolate-marshmallow mixture onto prepared baking sheet. Using a spatula, spread into an even layer approximately 1/2 inch thick, ensuring uniform thickness for consistent setting.
05 - Sprinkle chopped candy eggs and pastel sprinkles generously over surface. Press decorations lightly into chocolate to ensure adhesion during chilling.
06 - Refrigerate baking sheet for minimum 1 hour until bark is completely firm and set. Chocolate should break cleanly when touched.
07 - Remove from refrigerator and break or cut into irregular pieces. Serve immediately or store in airtight container.
