Difficulty Level
Easy - perfect for bakers of any skill level wanting extraordinary gooeyness
Ingredients
- 1 cup (226g) unsalted butter, melted and slightly cooled
- 2 cups (400g) granulated sugar
- 3 large eggs, at room temperature
- 1 tablespoon pure vanilla extract
- 1 cup (120g) all-purpose flour, sifted
- 1 cup (85g) unsweetened cocoa powder, fine and unsifted
- 1/2 teaspoon salt
- 1 teaspoon baking powder
- 1 cup semisweet chocolate chips or chunks

- Add eggs one at a time, beating well after each addition; follow with the vanilla extract to build a velvety batter base.
- In a separate bowl, sift together the flour, cocoa powder, salt, and baking powder to ensure even distribution and a light crumb.
- Fold the dry ingredients into the wet just until combined-avoid overmixing to keep brownies tender.
- Stir in chocolate chips gently, reserving a handful for topping.

- Sprinkle mini marshmallows and remaining chocolate chips across the top.For an extra campfire vibe,add crushed graham crackers here for subtle crunch and flavor layers.
- Bake for 25-30 minutes, starting to check at 22 minutes. The brownies should be set around the edges but slightly soft in the center-this ensures that rich gooeyness.
- Remove and let cool wholly in the pan before slicing. This step allows the marshmallows to set just right, achieving that perfect melting swirl without turning rubbery.
tips for Achieving the Ideal Marshmallow melt and Chocolate Swirl
To elevate the gooey, melty top, opt for fresh mini marshmallows and add them midway through baking. This prevents over-browning while allowing marshmallows to soften luxuriously. For the signature chocolate swirl, gently marble extra melted chocolate or fudge sauce onto the surface just seconds before baking-this creates mesmerizing pockets of molten richness that ooze with every bite.
Chef’s Notes
- Substitutions: Use coconut oil rather of butter for a dairy-free version. Adjust the cocoa powder slightly for darker or milkier chocolate notes.
- Make-ahead: Brownies keep well in an airtight container for up to 3 days or freeze for up to 1 month. Reheat briefly to revive gooey marshmallow goodness.
- Variations: Add chopped toasted nuts such as pecans or walnuts for texture. Try swapping semisweet chips for white chocolate or caramel chunks to personalize the campfire flavors.
- Troubleshooting: If brownies turn cakey, reduce flour slightly and avoid overbaking. For sticky marshmallows, tent with foil during the last 5 minutes of baking.

Q&A
Q&A: Decadent S’mores Brownies – A Gooey Campfire Classic Twist
Q1: What makes these s’mores brownies different from traditional brownies?
A1: While classic brownies are rich and fudgy on their own, these s’mores brownies blend that luscious chocolate base with the toasty, gooey charm of campfire s’mores. Marshmallows, graham cracker pieces, and melty chocolate chips are swirled and sprinkled throughout, creating a harmonious medley that’s both indulgent and nostalgic.
Q2: Why add graham crackers to brownies? Doesn’t that change the texture?
A2: Absolutely-and that’s the magic! The graham crackers introduce a delightful crunch and just a hint of honeyed warmth, cutting through the brownie’s dense richness. this contrast of textures keeps each bite interesting and delivers the unmistakable s’mores flavor without turning the brownies crumbly.
Q3: Can I use regular marshmallows or should I go for mini ones?
A3: Mini marshmallows are ideal because thay melt evenly, creating those signature pockets of gooeyness throughout your brownies. But if you only have large marshmallows, chop them roughly-they’ll still add that luscious, toasted delight, especially if you broil the finished brownies briefly for a golden top.
Q4: How do I get that perfect gooey marshmallow layer without making the brownies too sticky?

Q5: Is it necessary to toast the marshmallows with a kitchen torch or under the broiler?

Q6: What kind of chocolate works best for these brownies?
