Introduction

S’mores bars are a delightful twist on the classic campfire treat, combining graham crackers, melted marshmallows, and rich chocolate into a chewy, gooey dessert. Perfect for sharing at parties or enjoying as a sweet snack, these bars capture all the flavors of s’mores without the need for a campfire.

The image shows a stack of four square s'mores bars, each with three clear layers: the bottom layer is a crumbly, golden brown graham cracker crust; the middle layer consists of melted dark chocolate pieces; and the top layer is a gooey mix of white, fluffy marshmallows, some of which are slightly toasted and brown at the edges. The bars have a soft, chewy texture, and the layers are thick and even. The stack is on a white marbled surface with small white marshmallows scattered around. The background is softly blurred to keep the focus on the bars. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

30 graham crackers (2 packs), crushed into crumbs
1 cup unsalted butter, melted
1/4 teaspoon salt
16 ounces mini marshmallows (about 6 cups)
12 ounces milk chocolate chips

Instructions

Step 1: Preheat your oven to 350 degrees F (175 degrees C).
Step 2: In a bowl, mix the graham cracker crumbs (reserve ¼ cup for later), melted butter, and salt until well combined.
Step 3: Press the graham cracker mixture evenly into the bottom of a 9×13-inch baking pan. Bake for 10 minutes.
Step 4: Remove the pan from the oven and spread 4 cups of mini marshmallows evenly over the crust. Return to the oven and bake for another 10 minutes.
Step 5: Let the marshmallows cool for 5 minutes to allow them to deflate slightly.
Step 6: Sprinkle the entire 12-ounce bag of milk chocolate chips over the marshmallow layer in an even layer.
Step 7: Top the chocolate layer with the remaining marshmallows and the reserved ¼ cup of graham cracker crumbs. Bake for an additional 10 minutes.
Step 8: Let the bars cool completely before slicing to allow layers to set.

Tips & Variations

For a richer flavor, try using dark chocolate chips instead of milk chocolate.
Adding a sprinkle of chopped nuts on top before the final bake adds a nice crunch.
To make cleanup easier, line your baking pan with parchment paper.
Use jumbo marshmallows instead of mini for a different texture and appearance.

Storage

Store s’mores bars in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week. If refrigerated, allow the bars to come to room temperature before serving for the best texture. Reheating briefly in a microwave can help soften the marshmallows.

How to Serve

A rectangular baked dessert bar in a baking pan lined with parchment paper shows three main layers: the base is a golden-brown crust with a slightly puffed edge, the middle layer is melted dark chocolate chips spread unevenly, and the top layer is a mix of white mini marshmallows, some toasted to light brown, and crushed light brown cookie crumbs scattered over the surface. The overall texture looks soft and gooey with a mix of smooth and crunchy parts. Photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use regular-sized marshmallows instead of mini?

Yes, you can use regular-sized marshmallows; just cut them into smaller pieces to spread evenly over the bars.

How do I prevent the marshmallows from burning?

Bake at the recommended temperature and keep an eye on the bars during the final baking stage. If marshmallows start to brown too quickly, you can cover the pan loosely with foil.

Description

Deliciously gooey and crispy S’mores Bars featuring a buttery graham cracker crust, melted milk chocolate chips, and toasted mini marshmallows baked to perfection. These bars capture all the classic campfire flavors in an easy-to-make dessert perfect for any occasion.

Ingredients

Scale

Crust

30 graham crackers (2 packs), crushed to crumbs
1 cup unsalted butter, melted
1/4 teaspoon salt

Toppings

16 ounces mini marshmallows (about 6 cups), divided
12 ounces milk chocolate chips (1 bag)

Instructions

Preheat Oven: Preheat your oven to 350°F (175°C) to prepare for baking the bars.
Prepare Crust Mixture: In a mixing bowl, combine the crushed graham cracker crumbs, melted butter, and salt. Reserve 1/4 cup of the crumbs for topping later.
Form and Bake Crust: Press the graham cracker mixture evenly into the bottom of a 9×13-inch baking pan. Bake for 10 minutes until set and slightly golden.
Add Marshmallows and Bake: Remove the crust from the oven, evenly sprinkle 4 cups of mini marshmallows on top, and return to bake for another 10 minutes until marshmallows puff up and turn lightly golden.
Cool and Deflate Marshmallows: Let the pan cool for 5 minutes so the marshmallows deflate slightly, creating a better layer for the chocolate.
Top with Chocolate Chips: Evenly spread the entire 12-ounce bag of milk chocolate chips over the marshmallow layer.
Add Remaining Toppings and Bake Again: Sprinkle the remaining marshmallows and reserved graham cracker crumbs on top, then bake for an additional 10 minutes until marshmallows are toasted and chocolate begins to melt.
Final Cooling: Remove from oven and let cool completely to allow layers to set before slicing into bars.

Notes

For best results, allow the bars to cool completely so they hold their shape when sliced.
You can substitute semi-sweet chocolate chips if you prefer a less sweet flavor.
Using mini marshmallows helps in even melting and browning; large marshmallows can be chopped if necessary.
Store leftovers in an airtight container at room temperature for up to 3 days.
