S’mores Semifreddo

A sliceable chocolate semifreddo layered with buttery graham cracker crunch and crowned with toasted marshmallow cream for a frozen take on classic s’mores.

Prep Time:30 minCook Time:10 minTotal Time:40 minServings:10Difficulty:Medium

This semifreddo turns the three essential parts of a s’more into a cool dessert that still tastes unmistakably campfire-inspired. Dark chocolate gives the frozen cream a clean cocoa flavor, while two ribbons of graham cracker crunch keep every slice from feeling soft or one-note.

The base uses whipped cream and sweetened condensed milk, so it stays scoopable without an ice cream machine. Melted chocolate is cooled before folding to protect the airy texture, and a little salt keeps the finished dessert balanced.

Marshmallow cream is spread over the frozen loaf and toasted just before the final set. A kitchen torch gives the most even browning, but a brief pass under a hot broiler works when the loaf is kept well chilled and watched continuously.

Freeze the semifreddo at least six hours, then let it stand briefly before slicing. The graham layers soften slightly but retain a pleasant crunch, and the toasted marshmallow cap remains distinct against the cold chocolate center.

Directions

1

Line a 9-by-5-inch loaf pan with plastic wrap, leaving several inches of overhang on every side.
2

Stir the graham cracker crumbs, melted butter, brown sugar, and salt in a skillet over medium heat for 4 to 5 minutes, until fragrant and lightly toasted; spread on a plate to cool.
3

Melt the bittersweet chocolate in a heatproof bowl set over barely simmering water, stirring until smooth, then remove from the heat and cool for 8 minutes.
4

Whip the cold heavy cream in a large bowl to medium peaks. In a second bowl, whisk the condensed milk, cocoa powder, and vanilla until smooth, then whisk in the cooled melted chocolate.
5

Fold one-third of the whipped cream into the chocolate mixture to lighten it, then gently fold in the remaining cream until no white streaks remain.
6

Spread one-third of the chocolate mixture in the prepared pan and scatter with one-third of the graham crunch. Repeat the layers twice, ending with graham crunch, then fold over the plastic wrap and freeze until firm, at least 6 hours.
7

Uncover the frozen loaf, invert it onto a chilled platter, and remove the plastic. Spread the marshmallow cream over the top in soft peaks, then toast it evenly with a kitchen torch until deeply golden.
8

Freeze the topped semifreddo for 20 minutes to reset the surface, garnish with shaved milk chocolate, and let stand for 8 minutes before cutting into 10 slices with a warm dry knife.

Tips & Notes

If using a broiler instead of a torch, place the unmolded loaf on a freezer-safe metal tray and broil 8 inches from the heat for 20 to 40 seconds, watching constantly.
Return the loaf to the freezer between servings so the airy center keeps its clean sliceable shape.
Toast the graham crumbs only until fragrant; dark crumbs can taste bitter after freezing.
