S’Mores Cupcake Recipe: A perfect blend of classic campfire flavors.

We’ve crafted this recipe to be approachable for bakers of all skill levels, leaning on the convenience of a good quality box mix for the cake base. This not only saves you precious time but also ensures a consistent, moist, and delicious chocolate cupcake every single time. While any light chocolate cake mix will work wonderfully, we particularly recommend choosing your favorite brand for the best results. During our testing, we even tried a brownie mix, but found its dense texture didn’t quite achieve the desired cupcake lightness, so stick with a classic chocolate cake mix for that perfect spongy foundation.

The crowning glory of these S’mores cupcakes is undoubtedly the marshmallow frosting. It’s a deliciously gooey, fluffy cloud of sweetness that perfectly mimics the toasted marshmallows from a real s’more. Just one bite, and you’ll be transported straight to a crackling campfire, even if you’re enjoying these in your kitchen! These aren’t just chocolate cupcakes; they’re an experience waiting to happen.

If you’re a fan of unique dessert twists, you’ll absolutely adore these S’mores Cupcakes. And if you’re looking for more delightful treats, be sure to check out our Banana Pudding Brownies or our indulgent Snickers Bar Brownies!

Gather Your Groceries: Key Ingredients for the Ultimate S’mores Cupcakes

Creating these divine S’mores cupcakes requires a few essential ingredients that combine to build those iconic layers of flavor and texture. Below is an overview of what you’ll need. For precise quantities, please refer to the detailed recipe card at the bottom of this post.

Ingredients laid out on a table for making S'mores cupcakes, including graham crackers, chocolate cake mix, marshmallows, and butter.
All the delicious components ready to be transformed into S’mores magic.

The Crunchy Graham Cracker Crust:

  • Graham Cracker Crumbs: The foundational layer! You can buy these pre-crushed or easily make them yourself by pulsing whole graham crackers in a food processor or crushing them in a zip-top bag with a rolling pin.
  • Unsalted Butter: Essential for binding the crumbs and creating that firm, buttery crust. Ensure it’s melted before mixing.
  • Granulated Sugar: A touch of sweetness to enhance the graham cracker flavor.

The Moist Chocolate Cupcake Base:

  • Chocolate Cake Mix: Our shortcut to perfection! A standard 16-ounce box of your favorite chocolate cake mix works best. Look for one that promises a moist crumb.
  • Large Eggs, Water, Vegetable Oil: These are typically the liquid ingredients required by most box cake mixes to create a light and airy batter. Always follow the specific instructions on your chosen cake mix box for the best results.

The Dreamy Marshmallow Frosting:

  • Unsalted Butter (softened): Crucial for a smooth, creamy frosting base. Make sure it’s at room temperature for easy beating.
  • Powdered Sugar (Confectioners’ Sugar): Gives the frosting its sweetness and smooth texture. Sifting it can prevent lumps.
  • Vanilla Extract: Enhances all the sweet flavors in the frosting. Use pure vanilla extract for the best taste.
  • Marshmallow Creme (or Marshmallow Fluff): This is the star of the frosting, providing that distinct sticky, gooey marshmallow texture and flavor. Two 7-ounce jars are typically needed for a generous batch of frosting.

The Iconic S’mores Decorations:

  • Mini Hershey Chocolate Bars: Break these into small squares or rough pieces to scatter on top, mimicking the chocolate bar in a traditional s’more.
  • Mini Marshmallows: These are perfect for scattering on the frosting. You can even lightly toast them for an authentic campfire experience.
  • Chocolate Sauce: A drizzle of chocolate sauce adds an extra layer of chocolatey goodness and a beautiful visual appeal.

Having these ingredients ready before you start baking will make the process smooth and enjoyable, ensuring your S’mores Cupcakes turn out perfectly every time!

Recipe Walkthrough: Detailed Instructions for S’mores Cupcakes

This section provides a step-by-step overview to guide you through making these delightful S’mores cupcakes. For more precise measurements and detailed instructions, please consult the complete recipe card found at the very end of this article.

A large mixing bowl filled with golden graham cracker crumbs, melted butter, and sugar, ready to be mixed for the crust.
Step 1: Create the Graham Cracker Crust. In a mixing bowl, combine the graham cracker crumbs, melted butter, and granulated sugar until well mixed. The mixture should resemble wet sand.
Graham cracker crumbs being pressed firmly into the bottom of a cupcake liner in a muffin tin, forming the crust.
Step 2: Form the Crust Base. Place cupcake liners into a muffin pan. Take about a tablespoon of the graham cracker mixture and press it firmly into the bottom of each cupcake liner. Use the back of a spoon or your fingers to ensure a compact, even crust. This firm base is crucial for holding the cupcake together and providing that satisfying crunch.
A large mixing bowl filled with chocolate cake mix and other wet ingredients, being prepared according to package directions.
Step 3: Prepare the Chocolate Cake Batter. In a separate large mixing bowl, prepare your chosen chocolate cake mix according to the package instructions. This usually involves combining the mix with eggs, water, and vegetable oil. Mix until just combined, being careful not to overmix, which can lead to dry cupcakes.
Chocolate cake batter being carefully spooned into a muffin tin, over the prepared graham cracker crusts.
Step 4: Fill and Bake the Cupcakes. Spoon the prepared chocolate cake batter evenly over the graham cracker crusts in each cupcake liner. Fill each liner about two-thirds to three-quarters full to allow for proper rising without overflowing. Bake according to the cake mix package directions, or until a toothpick inserted into the center of a cupcake comes out clean. This indicates they are fully cooked.

Step 5: Cool Completely. Once baked, carefully remove the cupcakes from the muffin pan and transfer them to a wire rack. It is absolutely essential to allow the cupcakes to cool completely before attempting to frost them. Warm cupcakes will melt the frosting, creating a sticky mess.
A large mixing bowl containing softened butter, powdered sugar, and vanilla extract, ready to be beaten for the marshmallow frosting.
Step 6: Prepare the Marshmallow Frosting. In a large mixing bowl, combine the softened unsalted butter, powdered sugar, and vanilla extract. Beat these ingredients together with an electric mixer until light and fluffy. Then, slowly add the marshmallow crème (fluff) and continue beating until the mixture is well combined and forms stiff peaks. This creates that wonderfully gooey and stable marshmallow frosting.

Hint: For easy frosting and decorating, ensure you remove all cooled cupcakes from the muffin pan onto your working surface *before* you start piping the frosting. This prevents any accidental smudges or damage to your beautifully frosted creations when trying to take them out of the pan later.

  • Step 7: Frost and Decorate. Once the cupcakes are completely cool and the frosting is ready, generously frost each cupcake using a piping bag with your favorite tip, or simply a spoon. Then, get creative with your decorations! Sprinkle with graham cracker crumbs, mini chocolate pieces, mini marshmallows, and drizzle with chocolate sauce for that authentic S’mores appeal. You can even use a kitchen torch to lightly toast the mini marshmallows on top for an extra special touch.

Follow these steps, and you’ll have a batch of show-stopping S’mores cupcakes that are as delicious to eat as they are fun to make!

Recipe Variations and Substitute Ideas for Your S’mores Cupcakes

One of the joys of baking is the ability to customize recipes to your liking. Here are some fantastic variations and substitution ideas to make your S’mores cupcakes truly unique:

  • Toasted Marshmallows: For a truly authentic campfire experience, use regular-sized marshmallows (or even large ones, cut in half) on top of your frosted cupcakes. Use a kitchen torch to lightly toast them until golden brown and gooey. Be sure to do this just before serving for the best texture and flavor.
  • Homemade Cake: While we love the convenience of a box mix, if you prefer to bake from scratch, feel free to substitute a homemade chocolate cake recipe. A rich, moist chocolate cake will elevate these cupcakes even further. You’re clearly a pro!
  • A Pinch of Salt: Don’t underestimate the power of salt! Adding a small pinch (¼ to ½ teaspoon) to your cake batter or even the frosting can help balance the sweetness and bring out the deep chocolate flavors, creating a more complex taste profile.
  • Dark Chocolate Twist: Instead of traditional milk chocolate pieces, try using dark chocolate shavings or mini dark chocolate chips for a more intense chocolate flavor that contrasts beautifully with the sweet marshmallow.
  • Different Graham Cracker Flavors: Experiment with honey or cinnamon graham crackers for subtle variations in your crust. You could also use digestive biscuits for a slightly different texture and taste.
  • Chocolate Ganache Drizzle: For an extra luxurious touch, replace the chocolate sauce with a homemade chocolate ganache drizzle. It’s surprisingly easy to make and adds a rich, glossy finish.
  • Gluten-Free Option: To make these S’mores cupcakes gluten-free, simply use a gluten-free chocolate cake mix and ensure your graham cracker crumbs are also gluten-free. All other ingredients are naturally gluten-free.
  • Dairy-Free Option: With a few substitutions, these can be made dairy-free. Use a dairy-free chocolate cake mix (many are accidentally vegan), substitute dairy-free butter for the crust and frosting, and use a dairy-free marshmallow creme if available.

These variations allow you to tailor the S’mores cupcake experience to your preferences, making each batch a new adventure!

Necessary Gear: Essential Equipment for Baking S’mores Cupcakes

Having the right tools can make your baking experience much smoother and more enjoyable. For this S’mores cupcake recipe, you’ll need a few basic pieces of kitchen equipment:

  • Cupcake Pan (Muffin Tin): A standard 12-cup cupcake pan is essential for baking perfectly shaped cupcakes.
  • Cupcake Liners: These help prevent sticking, make cleanup easier, and add a nice presentation to your finished cupcakes.
  • Mixing Bowls: You’ll need at least two medium to large mixing bowls – one for the graham cracker crust, another for the cake batter, and a third for the marshmallow frosting.
  • Electric Mixer (Handheld or Stand Mixer): While you can mix some components by hand, an electric mixer is highly recommended for achieving light and fluffy cake batter and especially for beating the marshmallow frosting to stiff peaks.
  • Measuring Cups and Spoons: For accurate ingredient measurements.
  • Spatula or Spoon: For mixing and transferring batter and frosting.
  • Wire Cooling Rack: Crucial for allowing your cupcakes to cool completely and evenly, preventing them from becoming soggy.
  • Piping Bag and Tips (Optional but Recommended): For a professional-looking frosted cupcake, a piping bag with a large round or star tip works wonders for the marshmallow frosting.
  • Kitchen Torch (Optional): If you want to lightly toast your mini marshmallows on top for an authentic campfire look and taste.

How to Store Leftovers and Keep Your S’mores Cupcakes Fresh

While it’s unlikely you’ll have many leftovers of these irresistible S’mores cupcakes, it’s always good to know how to store them properly to maintain their freshness and deliciousness.

  • Room Temperature: The best way to store these cupcakes is in an airtight container at room temperature. The marshmallow frosting is stable at room temperature, and refrigerating it can sometimes alter its texture. Stored this way, your S’mores cupcakes will remain wonderfully fresh and moist for up to 3-5 days.
  • Avoid Refrigeration: We generally advise against refrigerating these cupcakes unless absolutely necessary, as it can dry out the cake and make the graham cracker crust less crisp. If you must refrigerate due to warm weather or other factors, make sure they are in a very well-sealed container and allow them to come to room temperature for about 30 minutes before serving for the best texture.
  • Freezing (Unfrosted): If you want to prepare ahead, you can bake the chocolate cupcakes and let them cool completely. Once cool, wrap them individually in plastic wrap and then place them in an airtight freezer-safe container or bag. They can be frozen for up to 2-3 months. Thaw at room temperature and then proceed with making the frosting and decorating.
  • Freezing (Frosted – not ideal): While technically possible, freezing frosted S’mores cupcakes is not ideal as the marshmallow frosting’s texture might change upon thawing, becoming a bit watery or losing its fluffiness.

By following these simple storage tips, you can enjoy your homemade S’mores cupcakes at their peak deliciousness for as long as possible!

Mel’s Kitchen Notes: Pro Tips for Perfect Cupcakes

One common challenge with cupcakes is when they rise into a significant dome shape. If your cupcakes have risen too much, creating a large dome, don’t worry! Simply use a sharp serrated knife to carefully slice off the tops to create a flat surface. This crucial step ensures you’ll have ample room to add your generous marshmallow frosting and all those delicious decorations without them sliding off or making the cupcake look top-heavy. A flat surface also helps in creating a more polished and professional-looking final product!

Another tip for moist cupcakes is to avoid overmixing the batter. Mix only until the ingredients are just combined. Overmixing develops the gluten too much, which can result in tough, dry cupcakes. A light hand will yield a tender, crumbly texture that pairs perfectly with the rich chocolate flavor and gooey frosting.

And remember, patience is a virtue in baking! Allowing your cupcakes to cool completely on a wire rack before frosting is non-negotiable. Trying to rush this step will only lead to melted frosting and a disappointing result. A fully cooled cupcake provides a solid, stable base for your marshmallow masterpiece.
