Toasted S'mores Cupcakes with Coffee-Enhanced Chocolate

A nostalgic campfire classic transformed into an elegant, architectural dessert.

The campfire classic, completely reimagined for the dining room table with mile-high, flame-kissed meringue.

There is a distinct thrill in receiving a spontaneous dinner invitation from friends who appreciate the art of a well-set table and a meticulously curated wine cellar. When tasked with bringing the dessert—a course I approach with exactness and a healthy dose of reverence—I wanted to deliver something that evoked sheer nostalgia but presented with absolute architectural drama. It required stepping away from the standard confection and crafting an experience that elicits an immediate chorus of "oohs" and "ahhs" as it arrives at the table.

This cupcake is a masterclass in texture and memory. It begins with a crisp, buttery graham cracker crust pressed firmly into the base, providing a necessary textural contrast to what comes next: a decadent, moist chocolate cake whose dark cocoa profile is brilliantly amplified by a generous pour of brewed coffee. The crowning glory, however, is the frosting. Rather than a dense buttercream, it is a towering peak of ethereal marshmallow meringue, kissed by the flame of a kitchen torch until its edges are perfectly, beautifully charred.

An Evening Among Friends

The genesis of this recipe was born from an evening filled with 70s disco music, excellent company, and a desire to elevate a beloved childhood memory. While my usual culinary contributions often lean toward the savory side of the kitchen, this occasion demanded a showstopper. After poring over the mechanics of a perfect s'more, I realized the secret was not just in mimicking the flavors, but in recreating the distinct structural experience: the snap of the cracker, the melt of the chocolate, and the warmth of the toasted marshmallow.

The structural components: Rich cocoa, freshly brewed coffee for depth, golden graham cracker crumbs, and the essential kitchen torch.

The Architectural Bake

To build this dessert properly, we treat it as an architectural feat. It begins with a firm foundation: baking the buttery graham cracker crust directly into the tin before the batter is even added. Next comes the crumb—a deeply rich chocolate cake that utilizes brewed coffee to darken and intensify the cocoa. Coffee does not make the cake taste like an espresso; rather, it acts as a magnifying glass for the chocolate, creating a far more sophisticated profile than standard hot water or milk would provide.

The true hosting strategy, however, lies in the finish. By utilizing a double boiler to warm the egg whites and sugar before whipping, we create a glossy, stable meringue that holds its shape magnificently. Taking a kitchen torch to these sweeping peaks provides an element of tableside theater, filling the dining room with the undeniable, comforting scent of caramelized sugar. It is a stunning, joyful end to a beautiful meal.

Ingredients
  

The Graham Cracker Crust
  • 2 sleeves graham crackers about 72 crackers
  • 4 tablespoons butter melted (½ stick)
  • ¼ cup granulated sugar
The Chocolate Coffee Cake
  • 2 cups unbleached all-purpose flour
  • 2 cups granulated sugar
  • 1 cup cocoa powder
  • 2 teaspoons baking soda
  • 1 teaspoon baking powder
  • 1 teaspoon kosher salt
  • 1 cup buttermilk
  • 1 cup brewed coffee
  • ½ cup vegetable oil
  • 2 large eggs
  • 1 teaspoon pure vanilla extract
The Marshmallow Meringue Frosting
  • 8 large egg whites room temperature
  • 2 cups granulated sugar
  • 1/4 teaspoon cream of tartar
  • 2 teaspoons pure vanilla extract

Method
 

Bake the Crust
  1. Preheat the oven to 350°F.
  2. Line two cupcake tins with paper liners.
  3. Use a food processor to pulse the graham crackers into crumbs.
  4. Pour in the melted butter and add the ¼ cup of sugar.
  5. Continue to pulse until the crackers come together to form coarse crumbs.
  6. Spoon 2 tablespoons of the crumbs into the bottom of each cupcake liner.
  7. Press down gently with the back of the spoon to form a solid base.
  8. Bake until the crumb crust is just beginning to turn brown, about 8 to 10 minutes.
  9. Remove from the oven and cool to room temperature.
Mix and Bake the Cupcakes
  1. Whisk together the flour, 2 cups of sugar, cocoa, baking soda, baking powder, and salt in a large bowl.
  2. Pour in the buttermilk, brewed coffee, and vegetable oil.
  3. Whisk to combine.
  4. Whisk in the eggs and vanilla.
  5. Continue to whisk until the batter is completely smooth and shiny.
  6. Pour the batter on top of the cooled graham cracker crusts, filling each liner to about ¾ full.
  7. Bake until a tester inserted into the center of the cupcakes comes out clean, about 22 to 25 minutes.
  8. Cool the cupcakes completely to room temperature.
Whip and Toast the Frosting
  1. Place the egg whites, the remaining 2 cups of granulated sugar, and cream of tartar into a bowl sitting over a pot of simmering water to create a double boiler.
  2. Whisk continuously until the sugar dissolves and the eggs are warm, about 5 minutes.
  3. Pour the warmed mixture into the bowl of an electric stand mixer.
  4. Beat the egg whites starting on low speed and gradually increasing to high speed.
  5. Whip until the frosting is beautifully shiny and stiff peaks form, about 5 to 7 minutes.
  6. Reduce the speed and mix in the vanilla extract.
  7. Use an ice cream scoop to dollop a generous, towering mound of frosting onto each cooled cupcake.
  8. Use a kitchen butane torch to gently brown the tips of the frosting to perfectly resemble a roasted campfire marshmallow.
