Individual S'more Tarts Recipe


Smore Tarts

When I was a kid, my dad would occasionally take me out on his boat on Lake Powell, a seemingly endless reservoir straddling the Utah-Arizona border. I don’t know which I looked forward to more — playing endlessly in the water or making s'mores over the open fire. This is a sophisticated version of the classic campfire treat. The homemade marshmallow topping is worth the effort, but store-bought marshmallow cream will work in a pinch. The s'mores can also be baked in a 9-inch tart pan. — Marisa Churchill, Sweet and Skinny

For the custard:

  • 2⁄3 cup liquid egg substitute
  • 2 tablespoons plus 1 teaspoon cornstarch
  • 1⁄3 cup plus 1 tablespoon sugar
  • 1 tablespoon good-quality unsweetened cocoa powder, Dutch-processed or natural
  • ¼ teaspoon salt
  • 1 ½ cups 2 percent milk
  • ¼ cup semisweet chocolate chips, melted
  • 1 graham cracker pie crust, formed in six 4 ½-inch tart shells with removable bottoms and baked  

For the marshmallow topping:

  • 2 ¼ teaspoons unflavored gelatin powder
  • Cold water, as needed
  • ½ cup plus 1 tablespoon sugar
  • 1⁄3 cup egg whites, from about 3 large eggs
  • ½ teaspoon pure vanilla extract


For the custard:

In a small bowl, whisk the egg substitute and cornstarch together; set aside.

Put the sugar, cocoa powder, and salt into a medium saucepan. Whisk in the milk. Bring to a boil over medium heat, stirring occasionally.

Pour about half of the hot milk mixture into the eggs in a steady stream, whisking constantly to avoid scrambling the eggs. Pour the mixture back into the saucepan and cook for several minutes, stirring constantly, until the custard is thick enough to coat the back of a spoon.

Pour the custard through a fine-mesh strainer into a medium bowl. Whisk in the melted chocolate. Cover the custard with plastic film, poking several holes in the film to allow steam to escape. Refrigerate for several hours, until it is cold.

Fill the baked tart shells with a scant 1⁄3 cup of custard each, spreading it evenly into the shells. Gently press up on the bottoms of the tart shells to remove the outer pan rings. Set aside.

For the marshmallow topping:

Turn on your broiler. 

Put the gelatin into a small bowl, add 1 ½ tablespoons water, and stir gently. Set aside for 5 minutes to soften.

In a small nonreactive saucepan, stir the sugar with ¼ cup water. Bring the mixture to a boil over medium heat, using a pastry brush dipped into cold water to brush any sugar crystals from the sides of the pan. Boil for 2 minutes, then remove from the heat and stir in the gelatin until it dissolves completely, at least 1 minute.

While the sugar is boiling, using a standing mixer fitted with a whisk attachment, beat the egg whites on high speed until they turn thick and foamy.

With the mixer running, pour the hot sugar syrup into the egg whites in a slow, steady stream, aiming it between the edge of the bowl and the beater. Continue beating for 5 minutes longer, or until the bottom of the bowl feels slightly warm to the touch. Add the vanilla and beat for 1 minute longer.

Without delay, transfer the topping to a piping bag fitted with a standard round tip. (Alternatively, use a resealable plastic bag: fill, press out the air, seal, and snip off one corner.) Pipe the topping onto the tarts in a spiral, starting at an outer edge and working your way toward the center. (If using store-bought topping, which does not pipe well, spoon it onto the tarts and toast it just before serving.)

Broil the tarts on a baking sheet in the upper third of the oven for 30-45 seconds, watching carefully and removing them as soon as the topping browns. 

Cut each tart in half, and serve immediately.
