Why These S’mores Bars are an Absolute Must-Try

What makes these S’mores Bars truly exceptional? Their unparalleled versatility and sheer ease of enjoyment. Unlike traditional s’mores, which require a blazing fire and can often result in burnt marshmallows and sticky fingers, these bars offer a clean, controlled, and equally delightful experience. They capture the essence of the classic campfire treat but in a format that’s perfect for any occasion, anytime, anywhere.

One of the biggest advantages is their incredible portability. Imagine bringing the joy of s’mores to a potluck, a backyard barbecue, a school event, or even a cozy slumber party. These bars travel beautifully, making them an ideal dessert solution when you need something delicious that can be easily transported and served. No more scrambling for sticks or worrying about rogue embers; just perfectly portioned, ready-to-eat squares of happiness.

Furthermore, these S’mores Bars offer flexibility in how they’re enjoyed. While they are undeniably divine served warm, with the chocolate and marshmallow still gloriously molten and oozing, they are equally fantastic once cooled. When warm, they embody that wonderfully messy, indulgent s’mores experience, guaranteed to bring smiles and maybe a few happy chocolate smudges. Left to cool on the counter, they firm up beautifully, allowing for cleaner cuts and easier handling, while still retaining all the rich flavors and delightful textures. Whether you prefer them decadently warm and melty or perfectly set and sliceable, these bars are a winner every time.

Bars are perfectly portable! The convenience of dessert bars is unmatched for gatherings.

Expert Tips & Frequently Asked Questions for Perfect S’mores Bars

To ensure your S’mores Bars turn out absolutely perfect every time, consider these invaluable tips and answers to common questions:

  • Homemade Marshmallow Creme (Fluff): If you find yourself without store-bought marshmallow creme or simply prefer a homemade touch, making your own is surprisingly simple and yields fantastic results. Over a very low heat, gently melt 7 ounces (approximately 4 ½ cups) of miniature marshmallows with 3 tablespoons of light corn syrup. Stir constantly until completely smooth and combined. Once melted, transfer the mixture to a bowl that has been lightly sprayed with cooking spray. Allow it to cool slightly; this will make it much easier to spread and prevent it from being too sticky. Your homemade marshmallow creme will glide right out of the bowl when you’re ready to incorporate it into the recipe. This method ensures a fresh, gooey marshmallow layer that truly elevates the bars.
  • The Value of a Kitchen Scale: For precise baking, especially when consistency is key, an inexpensive kitchen scale is an indispensable tool. While cup measurements are provided, measuring ingredients by weight (especially flour) offers superior accuracy, leading to more consistent results. This is particularly helpful when portioning out dough or batters, like ensuring even layers for your s’mores bars or splitting cake batter between multiple pans. Accuracy in baking reduces variables and increases your chances of success, making a kitchen scale a worthy investment for any enthusiastic baker.
  • Choosing Your Chocolate: While classic Hershey’s Milk Chocolate Bars are traditional for s’mores and ideal for their meltability and nostalgic flavor, feel free to experiment. Dark chocolate can add a sophisticated depth, while semi-sweet chocolate chips (or chunks) can be a good substitute if bars aren’t readily available. Just ensure your chosen chocolate melts well to create that signature gooey layer.
  • Cooling is Crucial: We know it’s hard to resist, but allowing your S’mores Bars to cool completely before cutting is paramount. This cooling period allows the chocolate and marshmallow layers to set, making for clean, neat squares. If cut too soon, the layers will be too soft and messy, though still delicious! Patience will be rewarded with perfectly structured bars.
  • Storage Tips: Store cooled S’mores Bars in an airtight container at room temperature for up to 3-4 days. For longer storage, they can be refrigerated for up to a week, or even frozen for up to 3 months. If frozen, thaw at room temperature before serving, and you can gently warm them in the microwave for a few seconds to restore some of that melty goodness.

Essential Ingredients for Your Delectable S’mores Bars

Crafting these heavenly S’mores Bars requires a handful of basic pantry staples, with just a couple of specific items that define the classic s’mores flavor. You’ll likely have most of these on hand already, making this recipe an accessible indulgence:

  • Unsalted Butter, softened: The foundation of our rich, cookie-like crust. Softened butter creamed with sugar creates a tender, flavorful base.
  • Granulated Sugar: Provides sweetness and helps achieve the perfect texture in the crust.
  • Large Egg: Acts as a binder, adding structure and moisture to the graham cracker crust.
  • Vanilla Extract: Enhances all the flavors, adding a warm, aromatic note to the cookie layer. Use good quality vanilla for the best taste.
  • All-Purpose Flour: The primary dry ingredient for the crust, giving it body and structure.
  • Graham Cracker Crumbs: The star ingredient for the crust, infusing it with that unmistakable s’mores flavor. You can buy pre-crushed crumbs or crush whole graham crackers yourself for a fresher taste and customizable texture. About 5-6 full graham cracker sheets typically yield ¾ cup of crumbs.
  • Baking Powder: A leavening agent that gives the crust a slight lift and tender crumb.
  • Salt: A pinch of salt balances the sweetness and enhances the overall flavor profile. Don’t skip it!
  • Hershey’s Milk Chocolate Bars: The iconic chocolate choice for s’mores. Four 1.5-ounce bars (totaling 6 ounces) are perfect for creating that classic melted chocolate layer. You can break them into squares or chunks for easy layering.
  • Marshmallow Fluff (Marshmallow Creme): This is the gooey, cloud-like topping that makes s’mores what they are. As mentioned in our expert tips, you can easily make your own if store-bought is unavailable or if you prefer a fresh version.

Beyond the marshmallow fluff and chocolate bars, most of these ingredients are kitchen staples, emphasizing how effortlessly you can whip up this delightful dessert!

Mastering the Art of S’mores Bars: A Step-by-Step Guide

These detailed step-by-step photos and instructions are here to guide you visually through each stage of making this recipe. For a concise, printable version of the recipe, please scroll down to the recipe card!

  1. Begin by preheating your oven to 350 degrees Fahrenheit (175 degrees Celsius). This ensures the oven is at the correct temperature for even baking from the moment your bars go in. Prepare an 8-inch square baking pan by lightly greasing it. For an even easier cleanup and removal, you can line the pan with parchment paper, leaving an overhang on the sides to create convenient “handles” for lifting the cooled bars out.
adding sugar to the bowl
  1. In a large mixing bowl, combine the softened butter and granulated sugar. Using an electric mixer, beat them together on medium speed until the mixture becomes light, fluffy, and creamy. This process incorporates air, contributing to a tender crust.
adding vanilla to eggs in bowl
  1. Next, crack in the large egg and pour in the vanilla extract. Continue beating with the electric mixer until all the ingredients are well combined and the mixture is smooth. Scrape down the sides of the bowl as needed to ensure everything is thoroughly incorporated.
adding baking powder to graham crackers
  1. In a separate small bowl, whisk together the dry ingredients: all-purpose flour, graham cracker crumbs, baking powder, and salt. This ensures that the leavening agent and salt are evenly distributed throughout the dough.

  1. Gradually add the dry ingredient mixture to the wet butter and sugar mixture. Beat on low speed until just combined. Be careful not to overmix, as this can develop the gluten in the flour too much, resulting in a tougher crust. Stop mixing as soon as no streaks of flour are visible.
hand spreading dough on waxed paper
  1. Prepare the top crust by taking your baking pan and turning it upside down. Place a piece of waxed paper on top, ensuring it’s slightly larger than the pan. Press half of the prepared dough evenly onto the waxed paper, using the bottom of the pan as a guide to achieve the correct size and shape. Set this aside. Then, turn the baking pan right-side up again.
Spreading marshmallow creme over dough in pan
  1. Press the remaining half of the dough evenly into the bottom of the prepared baking pan, forming the base crust. Next, spread the marshmallow cream (fluff) over this bottom layer of dough. Be sure to leave a small border around the edges, as the marshmallow will expand slightly during baking.
placing dough on top of chocolate layer
  1. Carefully lay the chocolate bars on top of the marshmallow creme layer. Break the chocolate bars apart as needed to create an even, continuous layer of chocolate across the entire surface. This ensures every bite gets that perfect chocolatey kick.
  2. Now, take the preformed dough layer that you set aside on the waxed paper earlier. Gently invert it directly onto the top of the chocolate layer. Carefully peel away the waxed paper, leaving the dough as the top crust. If necessary, gently spread the dough to the edges to fully cover the chocolate and marshmallow layers, but avoid pressing down too hard.
  3. Finally, bake the S’mores Bars in your preheated oven for 25-30 minutes. Baking times can vary slightly by oven (mine took exactly 27 minutes to achieve a beautifully golden-brown crust). The bars are done when the top crust is lightly golden and the marshmallow filling is bubbly. Once baked, remove the pan from the oven and, this is the hardest part, allow the bars to cool completely on a wire rack before attempting to cut them into squares. This cooling time is essential for the bars to set properly, ensuring clean, intact slices.

Once cooled and cut, prepare to be amazed by these incredibly gooey, rich, and utterly chocolatey S’mores Bars. They’re always a sensational hit, bringing smiles and nostalgic flavors to everyone who tries them!

Ingredients

  • ½ cup butter softened
  • ¾ cup sugar
  • 1 large egg
  • 1 teaspoon vanilla
  • 1 ⅓ cups flour
  • ¾ cup graham cracker crumbs about 5-6 sheets of graham crackers
  • 1 teaspoon baking powder
  • ¼ teaspoon salt
  • 6 ounces Hershey’s Milk Chocolate Bars 4 bars (1.5-ounce each)
  • 7 ounces marshmallow fluff

Things You’ll Need

  • Kitchen scale
  • 8 inch square baking pan
  • Mixing bowls
  • Electric mixer
  • Measuring cups and spoons
  • Baking spatula

Before You Begin

  • Don’t want to run to the store for marshmallow creme? Here’s how to make your own: Over low heat melt 7 ounces (about 4 1/2 cups) of miniature marshmallows and 3 tablespoons of light corn syrup. Let cool in a bowl sprayed with cooking spray. Your homemade marshmallow creme will slide right out when you are ready to add it to the recipe.
  • I highly recommend an inexpensive kitchen scale for so many recipes. It’s super handy when you have to portion out dough or batter, like splitting cake batter into pans. 

Instructions

  • Preheat oven to 350 degrees F (175 C). Lightly grease an 8-inch square baking pan. For easier removal, line the pan with parchment paper, allowing the sides to overhang as “handles.”
  • In a large bowl, beat the softened butter and granulated sugar with an electric mixer until creamy and light. Add the large egg and vanilla extract; continue beating until fully combined and smooth.
  • In a separate small bowl, combine the all-purpose flour, graham cracker crumbs, baking powder, and salt. Whisk these dry ingredients together thoroughly. Gradually add this dry mixture to the wet butter mixture, beating on low speed until just combined. Be careful not to overmix.
  • Turn the baking pan upside down. Place a piece of waxed paper on top. Press half of the dough evenly onto the waxed paper, using the pan’s bottom as a guide for size. Set this aside. Turn the baking pan right-side up.
  • Press the other half of the dough evenly into the bottom of the pan to form the base crust. Spread the marshmallow cream over this dough layer, leaving a small border around the edges. Lay the Hershey’s chocolate bars on top of the marshmallow creme, breaking them as needed to create an even layer of chocolate. Take the preformed dough from the waxed paper and carefully invert it onto the top of the chocolate layer, then gently peel away the waxed paper. Lightly spread the top dough layer to the edges if necessary.
  • Bake for 25-30 minutes, or until the top crust is lightly golden (mine baked for 27 minutes). Remove from the oven and cool completely on a wire rack before slicing into squares. This step is crucial for clean cuts and set layers.

The recipes on this blog are tested with a conventional gas oven and gas stovetop. It’s important to note that some ovens, especially as they age, can cook and bake inconsistently. Using an inexpensive oven thermometer can assure you that your oven is truly heating to the proper temperature. If you use a toaster oven or countertop oven, please keep in mind that they may not distribute heat the same as a conventional full sized oven and you may need to adjust your cooking/baking times. In the case of recipes made with a pressure cooker, air fryer, slow cooker, or other appliance, a link to the appliances we use is listed within each respective recipe. For baking recipes where measurements are given by weight, please note that results may not be the same if cups are used instead, and we can’t guarantee success with that method.
