Preheating is not usually necessary. If your air fryer automatically preheats, begin checking the marshmallows early.

Exposing the sticky interior of each marshmallow helps anchor it to the graham cracker so it does not move in the circulating air.

Milk chocolate provides a classic flavor, but dark, semisweet, or white chocolate can be substituted.

For a peanut butter or chocolate-hazelnut variation, spread a thin layer on the graham crackers before assembling.

Thin banana or strawberry slices can be added just before assembling the s’mores.

Try cinnamon, chocolate, or honey-flavored graham crackers for an easy variation.

Add a small pinch of flaky salt over the softened chocolate for a salty-sweet version.

For larger batches, arrange the crackers in a single layer without overcrowding the air fryer basket and cook in batches if necessary.

S’mores are best served immediately. Leftovers can be cooled completely and stored in an airtight container at room temperature for up to 1 day.

To reheat, air fry at about 300°F (150°C) for approximately 1 minute, watching carefully, then allow to cool briefly before eating.
