Ingredients

For the Crust and Topping

• 1 cup unsalted butter, softened
• 1 cup brown sugar
• 1/2 cup granulated sugar
• 2 large eggs
• 2 teaspoons vanilla extract
• 2 1/2 cups all-purpose flour
• 1 1/2 cups graham cracker crumbs
• 1 teaspoon baking powder
• 1/2 teaspoon salt

For the Filling

• 2 cups milk chocolate chips or chopped chocolate bars
• 3 cups mini marshmallows

Equipment Needed

• 9×13-inch baking pan
• Mixing bowls
• Electric mixer or whisk
• Spatula
• Measuring cups and spoons
• Parchment paper

Step-by-Step Instructions

Step 1: Prepare the Pan

Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving some overhang on the sides for easy removal.

Step 2: Make the Dough

In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.

Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

In a separate bowl, combine the flour, graham cracker crumbs, baking powder, and salt.

Gradually add the dry ingredients to the wet ingredients and mix until a soft dough forms.

Step 3: Create the Bottom Layer

Press about two-thirds of the dough evenly into the prepared baking pan. This will form the crust of your s’mores bars.

Step 4: Add the Chocolate

Sprinkle the chocolate chips or chopped chocolate evenly over the crust.

Step 5: Add the Marshmallows

Spread the mini marshmallows over the chocolate layer, covering the entire surface.

Step 6: Add the Top Layer

Take the remaining dough and gently flatten small portions with your fingers. Place these pieces over the marshmallow layer. The marshmallows should still be partially visible through the dough.

Step 7: Bake

Bake for 25–30 minutes, or until the top is lightly golden brown.

Step 8: Cool Completely

Allow the bars to cool completely in the pan before slicing. This helps the chocolate and marshmallow layers set properly.

Tips for Perfect S’Mores Bars

Use Quality Chocolate

High-quality chocolate bars provide the richest flavor and smoothest texture.

Don’t Overbake

The bars will continue to set as they cool. Overbaking can make them dry.

Let Them Cool

It can be tempting to cut into them right away, but waiting ensures clean slices and the best texture.

Line Your Pan

Parchment paper makes removing and cutting the bars much easier.

Delicious Variations

Peanut Butter S’Mores Bars

Add peanut butter chips along with the chocolate chips for a creamy twist.

Cookies and Cream S’Mores Bars

Mix crushed chocolate sandwich cookies into the filling.

Salted Caramel S’Mores Bars

Drizzle caramel sauce between the chocolate and marshmallow layers.

Dark Chocolate S’Mores Bars

Swap milk chocolate for dark chocolate for a richer flavor.

Mini Chocolate Bar Version

Use chopped chocolate candy bars instead of chocolate chips for extra texture.
