  • 1/4 cup mini chocolate chips (optional, for garnish)
  • 1/4 cup additional crushed graham crackers (optional, for garnish)

Instructions

7. Return cookies to the oven for 1–2 minutes, until marshmallows are puffed and just starting to melt.
8. For a toasted top, broil for 30 seconds, watching closely, until marshmallows turn golden brown.

10. Cool on baking sheets for 5 minutes, then transfer to a wire rack to cool completely.

Zusatztipps für die Zubereitung

To enhance the flavor of your cookies, consider swapping semi-sweet chocolate chips for dark chocolate chips or sprinkling a pinch of cinnamon into the dough for a subtle warmth. If you prefer a perfectly toasted marshmallow without broiling, use a kitchen torch for more control. Remember to store these treats in an airtight container to keep them fresh for up to 3 days.
