What You’ll Need to Make S’mores Crack Bars

• Graham Crackers: The sturdy base of this dessert that brings the signature crunch and honey flavor.
• Salted Butter: Adds rich, savory depth that balances the sweetness. Also the main ingredient in the crackly toffee layer.
• Light Brown Sugar: Essential for creating the gooey, caramel-like toffee layer. Adds warmth and chewiness.
• Chocolate Bars: Melty and rich, they provide that essential s’mores chocolate experience. Choose milk chocolate for classic flavor.
• Mini Marshmallows: Toast up beautifully under the broiler and bring the gooey, golden finish that defines this dessert.

Ingredient Swaps and Helpful Alternatives

Don’t have everything on hand? No worries — here are some easy substitutions to keep your S’mores Crack Bars game strong.

• Gluten-Free Graham Crackers: Swap in for a gluten-free version without sacrificing crunch.
• Dark Chocolate or White Chocolate: A deeper chocolate adds richness, while white chocolate offers a creamier, sweeter profile.
• Vegan Butter and Marshmallows: Make it dairy-free by using plant-based butter and gelatin-free marshmallows.
• Brown Butter: Want to elevate the flavor? Use brown butter for a nutty, rich depth in your toffee.

How to Make the Best S’mores Crack Bars – Step-by-Step

1. Preheat the Oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper for easy removal and cleanup.
2. Layer the Graham Crackers evenly across the base of the pan. Break them as needed to fit the entire bottom without large gaps.
3. Create the Toffee Layer: In a medium saucepan over medium-high heat, melt the butter with the brown sugar, stirring constantly. Let it come to a rolling boil and cook for 3–4 minutes until it thickens and turns slightly golden.
4. Pour the Toffee Mixture evenly over the graham crackers. Spread it out quickly to coat all pieces before it starts to set.
5. Bake the pan in the oven for 6–8 minutes. This helps set the toffee and bond it to the graham cracker layer.
6. Add the Chocolate and Marshmallows: Immediately after removing from the oven, scatter the chocolate pieces over the hot toffee base. Then sprinkle the mini marshmallows evenly across the top.
7. Broil for the Perfect Toast: Switch the oven to broil and place the pan back in the oven for 1–2 minutes. Watch closely — the marshmallows should turn golden brown but not burn.
8. Cool Completely before slicing. Let the bars set at room temperature for at least 20 minutes so the layers firm up. Slice into squares and serve.

Pro Tips for the Perfect S’mores Crack Bars

• Watch the Toffee: Stir constantly and don’t overcook — over-boiled toffee can harden too much. Aim for 3–4 minutes max.
• Quick with Toppings: As soon as it comes out of the oven, the toffee starts to firm — so add chocolate and marshmallows right away.
• Use Parchment Paper: It makes lifting the bars out for slicing a breeze and prevents sticking.
• Avoid Over-Broiling: Marshmallows toast fast. Stay near the oven to prevent them from burning.
• Cut When Cool: These bars slice best when they’ve fully cooled and set. Use a sharp knife for clean cuts.

Delicious Pairings and Creative Variations

Pair your S’mores Crack Bars with a tall glass of cold milk, hot cocoa, or coffee for a cozy dessert experience. Hosting a party? Add them to a dessert platter with brownies, cookies, or caramel popcorn.

Creative Variations to Try

• Nutty Crunch: Add chopped pecans or walnuts between the toffee and chocolate layer.
• Peanut Butter Twist: Drizzle peanut butter over the toffee layer before adding chocolate.
• Extra Chocolatey: Add chocolate chips along with the broken bars for double the melty goodness.
• Holiday Version: Use peppermint chocolate and top with crushed candy canes for a winter spin.
• Spicy Kick: Sprinkle a pinch of cayenne into the toffee for a sweet-heat surprise.

Storage and Make-Ahead Tips

• Store in an airtight container at room temperature for up to 5 days.
• For longer storage, refrigerate in layers separated by parchment paper.
• These bars can also be frozen for up to 2 months — just thaw at room temperature before serving.
