The warmth of the marshmallows melts the chocolate chips into gooey perfection, giving them a campfire taste and texture.

  • Prep time 45 minutes
  • Total time 4 hours & 45 minutes



Grease 9-inch (2.5 L) square cake pan; line with parchment paper. Lightly grease paper; dust with some of the icing sugar. Set aside.

In saucepan, bring granulated sugar, corn syrup and 1/2 cup water to boil over medium-high heat, stirring until sugar dissolves. Boil, without stirring but brushing down side of pan with pastry brush dipped in cold water, until candy thermometer reads 260°F (125°C) or 1 tsp mixture dropped in cold water forms hard ball, about 12 minutes. Remove from heat.

Meanwhile, in small saucepan, add cold water; sprinkle gelatin over top. Let stand until absorbed, about 5 minutes. Cook over low heat, stirring, until clear, 3 to 5 minutes. Whisk into hot sugar syrup (mixture will bubble up).

In stand mixer with whisk attachment, beat egg whites with salt until stiff peaks form. With machine running, gradually pour in sugar syrup, beating on high until increased in volume and cool, about 12 minutes. Beat in vanilla. Stir in chocolate chips and graham crackers.

Immediately scrape mixture into prepared pan. Using greased offset palette knife, smooth top. Dust with some of the remaining icing sugar. Let stand, uncovered, at room temperature until firm, about 3 hours.

Lift marshmallow out onto cutting board; using greased knife and cleaning and greasing knife between cuts, cut into 36 squares, trimming edges.

In bowl, gently toss marshmallows with remaining icing sugar to coat; dust off excess. Transfer to waxed paper–lined baking sheet. Let stand until dry, about 1 hour. Using dry pastry brush, brush off excess icing sugar. (Make-ahead: Cover loosely with plastic wrap; store at room temperature for up to 7 days.)

Tip from The Test Kitchen: Lightly grease your knife before slicing the marshmallows to get a clean, smooth cut.

Makes 36 marshmallows.
