Lightly toast the graham crackers in the air fryer at 350°F for 1-2 minutes before assembling to add crunch and prevent them from becoming soggy from the melting chocolate and marshmallow.

Instead of using a whole Hershey's bar, break it into smaller pieces and distribute them across the graham cracker to ensure even melting and consistent chocolate coverage in every bite.

Marshmallows can go from perfectly gooey to burnt in seconds—keep the air fryer door cracked or check at the 3-minute mark to catch them at peak melting without charring.

Line your air fryer basket with parchment paper to prevent sticking, make assembly easier, and simplify cleanup while allowing heat to circulate properly for even cooking.

Overlap your two graham crackers slightly before air frying so the chocolate and marshmallow act as a natural adhesive, creating a stable s'more that won't fall apart when you remove it.
