Remove the refrigerated pie crusts from their packaging and lay them out to come to room temperature, following the package instructions. Once ready, use a 3-inch cookie cutter to cut as many circles as possible from the dough, placing the cuts close together to maximize the number of pies you can make.

In a medium mixing bowl, combine the chopped chocolate bars, miniature marshmallows, and half of the crushed graham crackers. Stir everything together until the mixture is evenly combined. Add extra chocolate for a gooier center if desired.

Scoop about one tablespoon of the marshmallow mixture onto half of the pie dough cut-outs. Moisten the edges with water, top with another dough circle, and press gently to seal. Use a fork to crimp the edges for a decorative finish.

Brush the tops of each sealed mini pie with melted butter. Sprinkle the reserved crushed graham crackers over the buttered tops.

Preheat the air fryer, place the pies inside, and air fry until golden brown and filling is melted. Transfer to a wire rack to cool.

Arrange the cooled pies on a platter and serve with chocolate syrup and marshmallow cream for dipping.
