My roommate brought this 4 ingredient late night dessert to our weekend get together and the pan was wiped clean in seconds. Gooey sweet and tastes exactly like a campfire.

This 4-ingredient baked marshmallow chocolate dip is the kind of late-night dessert that disappears the second it hits the table. It has all the flavors of a campfire s’more—gooey toasted marshmallows and melted chocolate—but skips the smoke, bugs, and balancing act with skewers. Dips like this likely grew out of the American love affair with s’mores, first popularized in the early 20th century by campers and scout groups. Here, we simply layer chocolate and marshmallows in a small metal pan, bake until molten and toasty, and serve it straight from the oven for everyone to scoop and swipe. It’s unfussy, fast, and perfect for a casual weekend get-together when you want something sweet without committing to a full baking project.

Serve this dip piping hot in the same metal pan you baked it in, set on a trivet in the middle of the table. Surround it with a mix of dippers: graham crackers for classic campfire flavor, sturdy pretzels for a salty contrast, and sliced firm fruit like apples or pears if you want something fresh alongside the richness. A scoop of vanilla ice cream on the side turns it into more of a plated dessert, letting guests drizzle warm chocolate-marshmallow over cold ice cream. For drinks, coffee, hot cocoa, or a glass of cold milk echo the cozy, fireside feeling, while a not-too-sweet red wine or a stout beer pairs nicely with the dark chocolate.

Servings: 6

2 cups dark chocolate chips (60–70% cacao)

Preheat your oven to 400°F (200°C). Place an oven rack in the center position so the marshmallows toast evenly.

Lightly grease a round metal baking pan (8- or 9-inch works well) with the softened butter, coating the bottom and sides. This helps keep the chocolate from sticking and makes cleanup easier.

In a small saucepan over low heat, combine the dark chocolate chips and heavy cream. Stir constantly with a heatproof spatula until the chocolate is mostly melted and the mixture is smooth and glossy. Take it off the heat while a few small bits of chocolate remain; the residual heat will finish melting them.

Pour the warm melted chocolate mixture into the prepared metal pan and spread it into an even layer with the spatula, making sure it reaches the edges.

Scatter the mini marshmallows evenly over the top of the chocolate, covering the surface in a single, snug layer. A few gaps are fine, but the closer they sit, the more they’ll fuse into that gooey, pull-apart topping.

Place the pan on the center rack and bake for 6–9 minutes, keeping a close eye starting at the 5-minute mark. You’re looking for the marshmallows to puff and turn a deep golden brown on top, with some darker toasted spots that mimic campfire marshmallows.

Once the marshmallows are toasted to your liking and the chocolate is visibly melted and bubbling around the edges, carefully remove the pan from the oven. Let it sit for about 5 minutes; this brief rest keeps the dip molten but prevents the chocolate from being so hot that it burns your mouth.

Serve the pan straight on the table on a heatproof trivet. Offer graham crackers, pretzels, or firm fruit slices for dipping. Encourage guests to scoop straight down so they get both the toasted marshmallow cap and the smooth melted chocolate underneath in every bite.

For a stronger campfire vibe, line the bottom of the greased pan with a single layer of broken graham crackers before pouring in the melted chocolate; they’ll soften slightly and give you a built-in crust. To introduce a flavor twist without adding more ingredients, choose a different chocolate profile: bittersweet for a more grown-up dessert, or a mix of dark and semi-sweet chips if you prefer it sweeter. You can also switch to large marshmallows, halved horizontally and arranged cut-side down; they’ll toast in attractive domes, but may take a minute or two longer to color. If you like a smoky note reminiscent of a real fire, briefly finish the pan under the broiler, watching constantly so the marshmallows don’t burn. For make-ahead prep, you can assemble the greased pan with the cooled chocolate layer and marshmallows on top, then refrigerate for a few hours and bake just before serving—add 1–2 extra minutes to the bake time to account for the chill. Food safety tips: never leave the hot pan unattended around children, and always use oven mitts when handling the metal pan, which stays hot longer than it looks. Allow the dip to cool until it’s steaming rather than bubbling vigorously before serving, as melted chocolate can cause burns. Refrigerate any leftovers within 2 hours; reheat gently in a 300°F (150°C) oven until warm and gooey again, and discard if the dip has been left out at room temperature for more than 4 hours total.
