1 1/2 cups graham cracker crumbs: Provides the crisp, buttery base that holds everything together.
1/3 cup granulated sugar: Sweetens and helps bind the crust for a sturdy foundation.
6 tablespoons unsalted butter, melted: Adds rich flavor and moisture to the crust, ensuring it stays together.
2 cups semisweet chocolate chips: Melts into a silky, lush layer of chocolatey goodness.
14 ounces sweetened condensed milk: Binds the chocolate chips into a decadent, creamy filling.
1 teaspoon vanilla extract: Enhances the chocolate’s depth and brings warmth to every bite.
1/4 teaspoon salt: Balances the sweetness and elevates all the other flavors.

How To Make Decadent Gooey Toasted S’mores Bars

These bars come together in a few simple stages: creating a buttery crust, melting your chocolate filling, and finishing with perfectly toasted marshmallows. With just a bit of prep and a quick broil at the end, you’ll have warm, chewy squares that embody everything you love about classic s’mores—no campfire required!

1. Preheat oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper, leaving an overhang for easy removal—this ensures even baking and simple cleanup.

2. In a medium bowl, combine graham cracker crumbs, granulated sugar, and melted butter until the mixture resembles wet sand, which helps the crust hold its shape.

3. Press the crumb mixture firmly and evenly into the bottom of the prepared pan to form a compact crust that will bake up crisp.

4. Bake the crust for 8 to 10 minutes until lightly golden around the edges, then remove from the oven and set aside to keep it warm and ready for the filling.

5. While the crust bakes, place chocolate chips and sweetened condensed milk in a heatproof bowl and microwave in 30-second intervals, stirring between each, until the mixture is completely smooth and glossy.

6. Stir in vanilla extract and salt until fully incorporated, creating a balanced and flavorful chocolate layer.

7. Pour the chocolate mixture over the warm crust and use a spatula to spread it into an even layer for uniform gooeyness.

8. Evenly sprinkle mini marshmallows over the chocolate layer, making sure they cover the surface for that iconic toasted top.

9. Switch the oven to broil on high and place the pan on the top rack. Broil for 1 to 2 minutes—watching closely—until the marshmallows are toasted golden brown.

10. Remove from the oven and let cool for at least 15 minutes before lifting the bars out using the parchment overhang and cutting into squares for neat, gooey servings.

Serving Suggestions

These gooey bars are delightful on their own, but pairing them thoughtfully can elevate every bite. Whether you’re serving at a backyard gathering or winding down a cozy night in, these ideas will help you present them just right:

A La Mode: Top each warm square with a scoop of vanilla ice cream to contrast the gooey texture with cold creaminess.
Drizzled in Caramel: Add a ribbon of warm caramel sauce for an extra layer of sweetness and stickiness.
With Fresh Berries: Serve alongside tart raspberries or strawberries to cut through the richness and add a pop of color.
Campfire Tray: Place on a wooden board with skewers of extra marshmallows for a playful, interactive dessert experience.

Tips For Perfect Decadent Gooey Toasted S’mores Bars

These bars are forgiving, but a few insider tricks will guarantee maximum gooeyness and beautiful toasting every time. Follow these friendly pointers to ensure your s’mores bars come out picture-perfect:

Use dark chocolate chips for a richer, more intense chocolate flavor.
Keep a close eye on the marshmallows under the broiler to prevent burning.
Bars are best served slightly warm for maximum gooeyness.
Store any leftovers in an airtight container at room temperature for up to 3 days.

How To Store It

To keep your S’mores Bars at their gooey best, proper storage is key. Whether you enjoy them over a couple of days or need to prep ahead, these storage methods will preserve both flavor and texture:

Room-Temperature Airtight Container: Once completely cooled, place bars in a single layer or separated by parchment in an airtight container. Store at room temperature for up to 3 days to maintain that gooey center.
Refrigeration: If you need extra longevity, seal the cooled bars in a container and refrigerate for up to 5 days. Let them come to room temperature before serving to loosen the chocolate and marshmallows.

Frequently Asked Questions

Here are answers to your most common questions about these irresistible s’mores bars:

How long does it take to prepare and bake these S’mores Bars?

It takes about 5 minutes to mix and press the crust, 8–10 minutes to bake the crust, 5 minutes to melt and spread the chocolate mixture, 1–2 minutes to broil the marshmallows, plus at least 15 minutes of cooling time. In total, plan for roughly 35–40 minutes.

How do I prevent the marshmallows from burning under the broiler?

Make sure the oven rack is in the top position, switch to high broil, watch closely and remove when the marshmallows reach a golden brown color, which usually takes 1–2 minutes. Leaving the oven unattended can quickly lead to burnt marshmallows.

Can I substitute dark chocolate or different types of chocolate chips?

Yes. Using dark chocolate chips will yield a richer, more intense flavor, while milk chocolate will be sweeter and creamier. Just maintain the same 2 cups measurement for consistent texture and set.

My crust turns out too crumbly and doesn’t hold together. How can I fix that?

Ensure you use the full 6 tablespoons of melted butter and press the mixture firmly and evenly into the pan. Pressing with the bottom of a measuring cup helps compact the crumbs. Baking for the full 8–10 minutes also helps set the crust.

How should I store leftover bars and how long will they stay fresh?

Once completely cooled, transfer the bars to an airtight container and store at room temperature for up to 3 days. Storing in the refrigerator can cause them to firm up too much, losing their gooey texture.

Can I assemble these bars ahead of time and bake later?

Yes. You can bake the crust in advance and let it cool. Refrigerate the baked crust for up to 24 hours, then when you’re ready, melt and spread the chocolate mixture, add the marshmallows, broil, and serve.

How can I reheat leftover S’mores Bars to restore their gooey texture?

Place a bar on a microwave-safe plate and warm in 10–15 second intervals until the chocolate softens and the marshmallows regain their gooeyness. Avoid overheating to prevent the marshmallows from becoming rubbery.
