What makes this recipe gluten-free?

This recipe is gluten-free when made with certified gluten-free graham crackers. Many grocery stores carry at least one gluten-free brand in their specialty or gluten-free section. Check labels and ingredient lists to ensure any additional components—like marshmallows and chocolate chips—are processed in a gluten-free facility if you need strict gluten-free compliance.

One commonly recommended brand is Kinnikinnick S’moreables Graham Style Crackers, but any trusted gluten-free graham cracker will work.

Can these bars be made dairy-free or vegan?

Yes. With a few ingredient swaps you can make dairy-free or vegan s’mores bars:

• Graham crackers – Choose a dairy-free (and egg-free if needed) gluten-free graham cracker. Some certified gluten-free brands are also vegan.
• Butter substitute – Use a vegan buttery spread formulated to mimic butter flavor and texture. Avoid coconut oil or shortening, which change the texture of the crust.
• Chocolate chips – Use dairy-free or vegan chocolate chips.
• Marshmallows – Regular marshmallows often contain gelatin, so choose vegan marshmallows if you need the recipe to be fully vegan.

Ingredient notes

• Gluten-free graham crackers – Store-bought gluten-free graham crackers make this recipe quick, or you can use a homemade gluten-free graham cracker recipe if preferred.
• Unsalted butter – Using unsalted butter helps control the salt level; substitute a vegan buttery spread for a dairy-free version.
• Brown sugar – Brown sugar adds a rich, molasses-like flavor to the crust. Granulated sugar can be substituted if needed, but the flavor will be slightly different.
• Salt – A pinch of salt enhances the overall flavor.
• Ground cinnamon – A small amount adds warmth and depth to the crust without overpowering the s’mores flavors.
• Chocolate chips – Semi-sweet chips work beautifully, but milk or dark chocolate chips are fine. For a different twist, try peanut butter or butterscotch chips.
• Marshmallows – Mini marshmallows melt more evenly than full-size ones. Look for brands labeled gluten-free or use vegan marshmallows if needed.

Equipment:

• 9×13-inch baking dish (an 8×8-inch dish works if you cut the recipe in half)
• Parchment paper for easy removal
• Kitchen torch or your oven broiler to toast the marshmallows

Step-by-step instructions

These s’mores bars are made with seven simple ingredients and come together quickly—perfect for a last-minute dessert. The steps below outline the full process so you can recreate the recipe with confidence.

Prep: Preheat the oven to 350°F. Line a 9×13-inch baking dish with parchment paper.

1. Reserve 3–4 whole graham crackers for garnish. Add the remaining crackers to a food processor and pulse into fine crumbs (about 3 cups).
2. In a bowl combine the graham cracker crumbs with brown sugar, salt, and ground cinnamon. Stir in the melted butter until the mixture is evenly moistened.
3. Press the crust mixture into an even layer in the prepared 9×13-inch pan. Bake at 350°F for 10 minutes, until golden and fragrant. Remove from the oven.
4. Reserve 1 cup each of chocolate chips and mini marshmallows. Sprinkle the remaining chocolate chips evenly over the baked crust, then top with the remaining mini marshmallows.
5. Bake for another 10 minutes at 350°F, until the chocolate has softened and the marshmallows form a cohesive layer. Let the pan cool for a few minutes.
6. Scatter the reserved chocolate chips, marshmallows, and broken graham cracker pieces across the top. Use a kitchen torch to lightly toast the marshmallows to your liking. If you don’t have a torch, place the pan under the oven broiler for 1–2 minutes—watch closely to prevent burning.
7. Allow the bars to cool completely before slicing into squares so the layers set.
