2 hours to make
Ingredients
4 ounces bittersweet chocolate, chopped fine
1/2 cup heavy cream
1/4 cup light corn syrup
8 whole graham crackers, broken into pieces, plus 8 quartered along dotted seams
4 tablespoons unsalted butter, melted
1 tablespoon sugar
1 cup marshmallow creme
3 pints chocolate ice cream
26 large marshmallows, halved crosswise
Instructions
Combine chocolate, cream, and corn syrup in bowl and microwave at 50 percent
power until melted and smooth, about 1 minute, stirring halfway through
microwaving. Let cool completely, about 30 minutes.
Adjust oven rack to middle position and heat oven to 325 F. Spray 9-inch
springform pan with vegetable oil spray and line perimeter with 2 1/2-inch-wide
strip of parchment paper. Pulse crackers in food processor until finely ground,
about 15 pulses. Combine cracker crumbs, melted butter, and sugar in bowl until
mixture resembles wet sand. Using your hands, press crumb mixture evenly into
pan bottom. Using bottom of measuring cup, firmly pack crust into pan. Bake
until fragrant and beginning to brown, about 12 minutes. Let crust cool
completely in pan on wire rack, about 30 minutes.
Pour chocolate mixture over crust and smooth into even layer; freeze until firm,
about 30 minutes. Spread marshmallow crème over chocolate mixture in even layer;
freeze until firm, about 15 minutes. Scoop ice cream into large bowl and, using
large rubber spatula or wooden spoon, break up the scoops of ice cream. Stir and
fold ice cream to achieve smooth consistency. Spread softened ice cream evenly
over marshmallow creme layer. Cover with plastic wrap and freeze until ice cream
is very firm, at least 4 hours or up to 24 hours.
Adjust oven rack 6 inches from broiler element and heat broiler. Place cake on
rimmed baking sheet, discarding plastic, and arrange marshmallow halves, cut
sides down, in snug layer over top. Broil until marshmallows are lightly
browned, 30 to 60 seconds, rotating sheet halfway through broiling. (Refreeze
cake if necessary.) Working quickly, remove sides of pan, discarding parchment,
and slide thin metal spatula between cake bottom and pan bottom to loosen, then
slide cake onto platter. Arrange cracker pieces vertically along sides of cake.
Serve immediately.
