Key Ingredients

Let’s gather the ingredients that make these brownies sing. Each component plays a crucial role, from creating a fudgy base to delivering those iconic campfire flavors.

  • 1 cup unsalted butter: Provides rich fat to create a smooth, fudgy brownie base and help bind the ingredients.
  • 8 ounces semisweet chocolate chips: Melts into silky pockets of chocolate, delivering that signature gooey texture and deep flavor.
  • 1 cup granulated sugar: Sweetens the brownies and helps create a crackly top by dissolving into the melted chocolate.
  • 1 cup brown sugar: Adds moisture and a hint of molasses flavor for deeper sweetness and chewiness.
  • 4 large eggs: Binds the batter and contributes structure and richness for a tender, brownie texture.
  • 1 teaspoon vanilla extract: Enhances all the chocolatey flavors and adds a warm, aromatic note.
  • 1 cup all-purpose flour: Gives just enough structure to hold the gooey brownie together without becoming cake-like.
  • 1/2 cup cocoa powder: Intensifies chocolate flavor and adds a robust, bittersweet depth.
  • 1/2 teaspoon salt: Balances the sweetness and enhances the chocolate flavor for a more complex taste.
  • 6 graham cracker sheets coarsely crushed: Provides that classic crispy, slightly sweet crunch reminiscent of a campfire s’more.
  • 1/2 cup mini chocolate chips: Scatters extra melty chocolate surprises throughout the layers for pockets of deliciousness.
  • 12 large marshmallows halved: Tops the brownies with gooey, toasted marshmallow peaks that melt into the hot brownie surface.

How To Make Decadent Gooey Campfire S’mores Brownies

Baking these gooey campfire-inspired brownies is all about layering fudgy chocolate, crunchy graham crumbs, and gooey marshmallow in each pan. You’ll start by melting butter and chocolate together, whisk in your sugars and eggs, then gently fold in the dry ingredients. After spreading half the batter, you’ll build the s’mores layer with graham crackers and mini chips before topping it with marshmallows. Follow these steps for that perfect balance of crackly edges and melty centers.

1. Preheat the oven to 350°F and grease a 9×13-inch baking pan or line it with parchment paper to ensure easy removal.

2. Place a heatproof bowl over simmering water and melt the butter with semisweet chocolate chips, stirring occasionally until the mixture is completely smooth and glossy.

3. Remove the bowl from heat and whisk in the granulated sugar and brown sugar until the sugars are fully dissolved and the mixture looks shiny.

4. Add the eggs one at a time, whisking vigorously after each addition to create an emulsion, then stir in the vanilla extract for extra aroma.

5. Sift in the all-purpose flour, cocoa powder, and salt, then gently fold the dry ingredients in with a spatula until just combined—avoid overmixing.

6. Pour and spread half of the batter evenly into the prepared pan, creating a smooth, level base for the s’mores layer.

7. Evenly sprinkle the crushed graham crackers and mini chocolate chips over the first chocolate layer to build that classic s’mores texture.

8. Dollop the remaining batter over the graham cracker layer with spoonfuls, then gently spread to cover the layer without disturbing the crumbs below.

9. Arrange the marshmallow halves cut-side up on top of the batter for those signature gooey peaks that will toast beautifully.

10. Bake for 25 to 30 minutes, or until the edges are set and slightly pulling away while the center still jiggles gently when you tap the pan.

11. Let the brownies cool in the pan for at least 15 minutes before slicing into squares to allow the marshmallows to set without tearing.

  • Serve warm with a scoop of vanilla ice cream or a drizzle of chocolate sauce for contrasting temperatures and textures.

Frequently Asked Questions

Here are answers to some of the most common queries about these gooey s’mores brownies:

  • Q: How long does it take to prepare and bake these gooey campfire s’mores brownies?

A: It takes about 15 minutes to prep (chopping, melting, mixing, and layering) plus 25 to 30 minutes of baking time. Allow an additional 15 minutes for cooling in the pan before cutting, for a total of roughly 55 to 60 minutes from start to finish.

  • Q: How can I tell when the brownies are perfectly baked but still gooey in the center?

A: The brownies are done when the edges appear set and slightly pulled away from the pan, while the center still jiggles gently. If you insert a toothpick into the center, it should come out with moist crumbs, not completely clean. Begin checking at 25 minutes to prevent overbaking.

  • Q: Can I substitute milk or dark chocolate for the semisweet chocolate chips?

A: Yes. Use an equal weight of milk or dark chocolate chips in place of the semisweet. If using milk chocolate, you may wish to slightly reduce the brown sugar by 1 to 2 tablespoons to balance sweetness. With dark chocolate, the flavor will be richer and slightly more bitter, so no sugar adjustment is needed unless you prefer sweeter brownies.

  • Q: How should I store any leftover brownies, and what is the best way to reheat them?

A: Store cooled brownies in an airtight container at room temperature for up to 3 days. To reheat, microwave individual squares for 10 to 15 seconds until warm and gooey, or place them in a 300°F oven for 5 to 7 minutes. Serve with ice cream or a drizzle of chocolate sauce for best results.

  • Q: Can I use mini marshmallows instead of halved large marshmallows?

A: You can, but mini marshmallows may melt more quickly and lose their shape. To maintain gooey pockets, gently press them into the top of the batter before baking and expect them to collapse slightly. Use about 1½ cups of mini marshmallows in place of the 12 halved large ones.

  • Q: Is it possible to make the brownies ahead of time and bake them later?

A: Yes. Prepare up through step 8 (layering graham crackers and chocolate chips, then topping with the remaining batter), cover the pan tightly, and refrigerate for up to 24 hours. When ready to bake, let the pan sit at room temperature for 20 minutes, arrange the marshmallow halves on top, then bake as directed, adding an extra 2 to 3 minutes if the batter is cold.

  • Q: How can I adapt this recipe to be gluten-free?

A: Substitute the all-purpose flour with a 1:1 gluten-free baking flour blend and verify that your cocoa powder, chocolate chips, and marshmallows are labeled gluten-free. No other changes are necessary; the brownies will remain decadent and chewy.
