Line a baking sheet with parchment paper to prepare for setting the clusters.
Combine the chocolate chips and butter in a heatproof bowl. Place the bowl over a saucepan with simmering water, making sure the bowl doesn't touch the water.
Stir gently with a spoon until the chocolate and butter melt into a smooth, glossy mixture, about 3-5 minutes. The smell of melting chocolate will fill your kitchen.
Remove the bowl from heat and fold in the roasted peanuts, ensuring they are thoroughly coated in the melted chocolate.
Using a spoon or small scoop, drop dollops of the mixture onto the prepared parchment, spacing them evenly. You can press down slightly if you want a flatter cluster.
Sprinkle a tiny pinch of sea salt on top of each cluster for an extra flavor boost, if desired.
Let the clusters sit at room temperature for about 30 minutes or until they start to set. You’ll notice the chocolate firms up and becomes shiny.
For quicker setting, transfer the tray to your refrigerator and chill for at least 1 hour until the clusters are firm and glossy.
Once fully set, break apart any larger clusters if needed. Store in an airtight container at room temperature or in the fridge for up to a week.
Enjoy these rich, crunchy bites whenever you crave a nostalgic, no-fuss treat.
