01 - Line a baking sheet with parchment paper. Insert a lollipop stick or skewer into each marshmallow if desired to facilitate dipping.
02 - Place chopped chocolate in a heatproof bowl and melt gently over simmering water (double boiler method), stirring until smooth. Alternatively, melt in the microwave in 20-second intervals, stirring between bursts.
03 - Dip each marshmallow halfway into the melted chocolate, allowing excess to drip off.
04 - Immediately sprinkle the chocolate-coated portion with colorful sprinkles before the chocolate sets.
05 - Place dipped marshmallows on the prepared baking sheet. Allow to sit at room temperature or refrigerate for 10 to 15 minutes until the chocolate hardens.
06 - Serve immediately or store in an airtight container at cool room temperature for up to three days.
