Begin by preparing your baking sheet. Line it with parchment paper to prevent sticking. If you have silicone molds, place them on the baking sheet for easy handling.
In a double boiler or microwave-safe bowl, melt the milk chocolate chips over low heat or in 30-second intervals in the microwave, stirring until smooth.
Once melted, pour the milk chocolate into the prepared molds or spread it evenly on the parchment-lined baking sheet.
While the chocolate is still warm, sprinkle mini marshmallows, crushed graham crackers, chopped nuts (if using), and Easter-themed sprinkles over the top.
In a separate bowl, melt the dark chocolate chips the same way as the milk chocolate until smooth.
Drizzle the melted dark chocolate over the treats for a decorative finish.
Place the baking sheet or molds in the refrigerator for about 30 minutes or until the chocolate has fully set.
Once set, remove the chocolate from the molds or break it into pieces if set on the baking sheet.
Serve and enjoy your festive Easter chocolate treats!
