Introduction

S’mores Cookie Bars combine the nostalgic flavors of classic campfire treats into an easy, crowd-pleasing dessert. With a crunchy graham cracker base, gooey marshmallows, melted chocolate, and a soft cookie topping, these bars are perfect for any occasion.

The image shows a stack of three square dessert bars that have three clear layers: the bottom layer is a golden brown, crumbly cookie base; the middle layer is white and fluffy with visible melted marshmallows; and the top layer is crumbly cookie dough with large dark chocolate chips scattered throughout. The bars have a rough, textured surface with gooey white marshmallow mixed with rich chocolate chunks inside. They are placed on white parchment paper over a white marbled surface. Around the stack, more pieces of the same bars are scattered in a blurred background, giving a cozy and inviting look. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

7-8 full rectangles graham crackers
1 cup (2 sticks) unsalted butter, room temperature
3/4 cup granulated sugar
3/4 cup light brown sugar, packed
2 large eggs
2 tsp vanilla extract
3 cups all-purpose flour
3/4 tsp salt
3/4 tsp baking soda
1/2 cup semi-sweet chocolate chips
1 cup mini marshmallows
2 regular-sized (1.55 oz) Hershey’s milk chocolate bars, broken into squares

Instructions

Step 1: Preheat your oven to 375°F (190°C). Line a 13×9-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal.
Step 2: Arrange the graham crackers in a snug layer at the bottom of the prepared pan, breaking them as needed to fit and cover the entire surface.
Step 3: In a mixing bowl, beat the softened butter with granulated sugar and light brown sugar until creamy and smooth. Add the eggs one at a time, then mix in vanilla extract.
Step 4: In a separate bowl, whisk together all-purpose flour, salt, and baking soda. Gradually add the dry ingredients to the butter mixture, mixing until just combined.
Step 5: Gently fold in the semi-sweet chocolate chips and mini marshmallows, being careful not to overmix.
Step 6: Spread the cookie dough evenly over the graham cracker base in the pan, pressing down lightly to ensure a uniform layer.
Step 7: Bake for 25-30 minutes or until the top is golden. If the bars begin to brown too quickly, cover loosely with foil to prevent over-browning.
Step 8: Immediately after removing from the oven, sprinkle the broken Hershey’s chocolate squares over the hot bars, allowing the chocolate to melt slightly.
Step 9: Let the bars cool in the pan for 20-30 minutes, then use the parchment overhang to lift them out. Cut into squares and serve.

Tips & Variations

For extra gooeyness, add a layer of chocolate spread under the cookie dough before baking.
Substitute the semi-sweet chocolate chips with milk or dark chocolate chips to adjust sweetness.
If mini marshmallows aren’t available, large marshmallows can be chopped into smaller pieces.
Make it nutty by folding in chopped toasted nuts like almonds or pecans into the dough.

Storage

Store the cooled s’mores cookie bars in an airtight container at room temperature for up to 3 days. For longer storage, keep them refrigerated for up to a week, or freeze for up to 3 months. To reheat, warm gently in the microwave for 10-15 seconds to revive that melty texture.

How to Serve

The image shows a batch of nine square blondies arranged on white parchment paper over a cooling rack, placed on a white marbled surface. Each blondie has a light brown, slightly cracked top layer with a firm and chewy texture. The top is studded with scattered dark chocolate chips that are slightly melted, and small toasted marshmallows that are puffed and creamy white with light golden-brown spots. The edges of the blondies are more baked and slightly darker. The inside appears soft and dense with spots of gooey chocolate. Photo taken with an iphone --ar 4:5 --v 7
