Introduction

S’mores Bars are a delightful twist on the classic campfire treat, combining layers of graham cracker dough, rich chocolate, and gooey marshmallow creme. This easy-to-make dessert is perfect for satisfying your sweet tooth anytime, no campfire required.

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 your 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 combined.
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 on low speed until just combined.
Step 6: Divide the dough in half. Press half of the dough evenly across the bottom of the prepared pan, using your fingers to spread it out.
Step 7: Place the chocolate bars side by side on top of the dough. Break the chocolate if needed to fit 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 pieces and layer them on top of the marshmallow creme, covering as much as possible.
Step 10: Bake for 30 to 35 minutes, or until the top is a light golden brown.
Step 11: Allow the bars to cool completely before cutting into squares.

Tips & Variations

Use a bench scraper or spatula to help press the dough layers evenly if your fingers get too sticky.
Substitute semi-sweet or dark chocolate bars for a richer flavor.
Add a sprinkle of sea salt on top before baking for a sweet and salty contrast.
For a nutty twist, mix chopped toasted nuts into the dough.

Storage

Store the s’mores bars in an airtight container at room temperature for up to 3 days. For longer storage, keep them refrigerated for up to a week. To enjoy warm gooey bars, microwave individual pieces for 10-15 seconds before serving.

How to Serve

Two square pieces of a dessert bar are stacked on a white plate, each showing three visible layers. The top layer is a crumbly, golden-brown baked crust with a rough texture. 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 regular marshmallows instead of marshmallow creme?

Yes, you can use mini marshmallows spread over the chocolate bars. Just be sure to press them down slightly to stick and adjust baking time if needed to prevent burning.

What pan size should I use if I don’t have an 8-inch square pan?

An 8-inch square pan is ideal for these bars, but you can use a 9×9-inch pan as well. The bars may be slightly thinner and bake a few minutes faster, so watch closely near the end of baking.
