Line a large sheet tray with parchment paper and set your oven to broil on high.
Spread the popcorn onto the tray in an even layer.
Break up the graham crackers and scatter them over the top.
Sprinkle the marshmallows evenly, then add the peanuts.
Place the tray under the broiler for about 30 seconds, or until the marshmallows are puffed and golden brown. ⚠️ Keep a close eye on them! They toast fast — it’ll go from perfect to burnt in seconds.
Remove the tray from the oven and drizzle generously with Torani Dark Chocolate Sauce (or Hershey’s syrup).
Serve immediately while the marshmallows are still warm and gooey.
Store leftovers in an airtight container at room temperature for up to 3 days.
