Description
These oven-baked S’more Bars capture all the gooey, melty magic of classic campfire s’mores in a soft, chewy dessert bar. Packed with graham crackers, chocolate, and marshmallows, they’re the perfect fall comfort treat.
Ingredients
- 1 cup (2 sticks) unsalted butter, melted
- 1½ cups light brown sugar, packed
- 2 large eggs
- 2 teaspoons pure vanilla extract
- 2 cups all-purpose flour
- 1½ cups crushed graham crackers (about 12 full sheets)
- 1 teaspoon baking powder
- ½ teaspoon salt
- 1½ cups semi-sweet chocolate chips (or chopped chocolate)
- 2 cups mini marshmallows
- ½ cup crushed graham crackers (for sprinkling)
Instructions
- Preheat your oven to 350°F (175°C).
- Line a 9×13-inch baking pan with parchment paper or lightly grease it for easy removal.
- In a large bowl, whisk together melted butter and brown sugar until smooth.
- Beat in the eggs and vanilla extract until fully incorporated.
- In a separate bowl, combine flour, graham cracker crumbs, baking powder, and salt.
- Gradually add the dry ingredients to the wet, stirring until a soft dough forms.
- Press two-thirds of the dough into the bottom of your prepared baking dish to form an even layer.
- Sprinkle the chocolate chips evenly over the dough.
- Add a layer of mini marshmallows.
- Crumble the remaining dough over the top in chunks—it won’t fully cover the marshmallows, and that’s okay!
- Sprinkle the last ½ cup of crushed graham crackers over the top for a rustic finish.
- Bake for 25–30 minutes, or until the top is golden brown and the edges begin to pull away from the sides.
- Allow the bars to cool completely in the pan before slicing for the cleanest cuts.
Notes
Cool before cutting for clean slices. Use parchment for easy removal. Don’t overbake—bars set more as they cool. Customize with streusel, peanut butter chips, or nuts for creative twists.

🎯 Tips for Perfect S’more Bars Every Time
Here are a few simple tricks to make sure your bars turn out perfectly gooey, chewy, and packed with flavor:
- Cool before cutting: Let the bars set before slicing. This helps the chocolate firm up slightly and gives cleaner edges.
- Use parchment paper: It makes removal a breeze and keeps cleanup easy.
- Don’t overbake: The bars will continue to set as they cool, so take them out when the top is just golden.

Want to switch things up or accommodate dietary needs? These fun variations will help you customize your S’more Bars:
Gluten-Free Version
- Swap the all-purpose flour for a 1:1 gluten-free baking flour.
- Use certified gluten-free graham crackers.
Add a Streusel Topping
- Mix ¼ cup oats, 2 tablespoons brown sugar, and 2 tablespoons cold butter.
- Crumble this mixture on top of the bars before baking for extra texture and sweetness.
Chocolate Peanut Butter Twist
- Add a ½ cup of peanut butter chips along with the chocolate chips.
- Or swirl in a couple tablespoons of peanut butter over the base layer before adding the marshmallows.
Nutty Crunch
- Sprinkle chopped walnuts or pecans over the top for a toasty crunch that pairs beautifully with the marshmallows.
