Place the chocolate chips and peanut butter in a microwave-safe bowl. Microwave in 20-second bursts, stirring each time until the mixture is smooth, glossy, and fully melted.
Add the honey or maple syrup to the melted mixture and stir well to combine. This helps make the clusters sticky and easier to form.
Pour the roasted peanuts into the melted chocolate mixture. Use a spatula to fold everything together until the peanuts are evenly coated with the glossy chocolate mixture.
Use a spoon or cookie scoop to portion out small mounds onto the parchment-lined tray. Gently press down if you prefer flatter clusters.
Place the tray in the fridge and chill for at least 30 minutes until the clusters are firm and the chocolate coating is set to a shiny finish.
Once set, transfer the clusters to an airtight container, layering with parchment paper to prevent sticking. Store in the fridge for up to 2 weeks or freeze for longer storage.
