How to Make Classic S’mores Bars
Making Classic S’mores Bars is a straightforward process. Here’s how to do it:
Ingredients:
- 2 cups graham cracker crumbs
- 1/2 cup unsalted butter, melted
- 1 cup light brown sugar, packed
- 1/2 cup granulated sugar
- 1 1/2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 4-5 milk or dark chocolate bars (approx. 1 1/2 cups)

Directions:
Prepare the Baking Dish: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish or line it with parchment paper for easy removal.
Make the Crust: In a large mixing bowl, combine the graham cracker crumbs, melted butter, brown sugar, granulated sugar, flour, baking powder, and salt. Stir until the mixture is well combined and resembles wet sand.
Press into the Dish: Reserve about 1 cup of this mixture for the topping. Take the remaining crumbs and press them firmly into the bottom of the prepared baking dish.
Add Chocolate Layer: Lay the chocolate bars evenly over the crust. Make sure to cover the entire base.
Add Marshmallows: Sprinkle the mini marshmallows over the chocolate layer.
Add Crumb Topping: Crumble the reserved graham cracker mixture over the top of the marshmallows.
Bake: Place the dish in the preheated oven and bake for about 20-25 minutes, or until the marshmallows are golden brown and the crumb topping is set.
Cool and Cut: Allow the bars to cool in the pan for at least 15 minutes. Then, cut into squares and serve.
