Introduction

These S’mores Bars capture the classic campfire treat in an easy-to-bake dessert bar. Layers of buttery graham cracker dough, rich milk chocolate, and fluffy marshmallow creme come together for a gooey, irresistible treat perfect for any occasion.

The image shows two square bars stacked on top of each other on a white marbled surface. Each bar has three main layers: the top and bottom layers are golden brown and crumbly with a rough texture, resembling baked cookie dough. The middle layer is thick and gooey with two colors: dark brown chocolate and white marshmallow, which looks soft and melted. The gooey middle slightly oozes out from the sides, giving it a rich, melted look. photo taken with an iphone --ar 4:5 --v 7

Ingredients

½ cup butter (softened to room temperature)
¼ cup brown sugar
½ cup sugar
1 egg
1 teaspoon vanilla
1⅓ cups flour
¾ cup graham cracker crumbs
1 teaspoon baking powder
¼ teaspoon salt
3 King Size Hershey Milk Chocolate Bars (3 bars, 2.6 ounces each)
7 ounces marshmallow creme (1 container)

Instructions

Step 1: Preheat the oven to 350°F and grease an 8-inch square baking pan.
Step 2: In a large bowl, cream together the softened butter, brown sugar, and sugar until the mixture is light and fluffy.
Step 3: Beat in the egg and vanilla until fully incorporated.
Step 4: In a separate small bowl, whisk together the flour, graham cracker crumbs, baking powder, and salt.
Step 5: Gradually add the dry ingredients to the butter mixture, mixing at low speed until combined.
Step 6: Divide the dough in half. Press half of the dough evenly into the bottom of the prepared pan using your fingers for best results.
Step 7: Arrange the chocolate bars over the bottom dough layer. Break the chocolate bars if necessary to fit them side by side in a single layer about ¼ inch thick.
Step 8: Spread the marshmallow creme evenly over the chocolate layer.
Step 9: Shape the remaining dough into small, flat shingles and lay them over the marshmallow creme to form the top layer.
Step 10: Bake for 30 to 35 minutes, until the top is a light golden brown.
Step 11: Allow the bars to cool completely before cutting into squares and serving.

Tips & Variations

Use your fingers to press the dough layers evenly for the best texture and coverage.
Try substituting dark or semi-sweet chocolate for a richer flavor.
You can add a pinch of cinnamon to the dry ingredients for a warm, spicy twist.
For a nutty variation, sprinkle chopped toasted nuts over the marshmallow layer before adding the top dough.

Storage

Store the S’mores Bars in an airtight container at room temperature for up to 3 days or refrigerate for up to a week. Reheat gently in the microwave for about 10 seconds to soften the chocolate and marshmallow before serving, if desired.

How to Serve

The middle layer is fluffy, white marshmallow that slightly oozes out the sides. The bottom layer is a smooth, melted chocolate with a rich, dark brown color. The edges look soft and gooey, showing the mix of the marshmallow and chocolate inside. The plate sits on a white marbled texture. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use mini marshmallows instead of marshmallow creme?

Marshmallow creme is recommended because it spreads easily to form a smooth layer. If using mini marshmallows, sprinkle them over the chocolate and bake; however, the texture will be less uniform.

Can I make these bars ahead of time?

Yes, you can prepare the bars a day in advance, store them covered, and they will remain fresh. Just be sure to cool them completely before storing to avoid trapping moisture.
