The Magic of Campfire Flavors in Cupcake Form

There’s something almost magical about the classic combination of graham crackers, melty chocolate, and toasted marshmallows. That first bite of a s’more takes you right back to childhood campfires, starry nights, and stories shared with loved ones. But what if you could capture those same flavors in a perfectly portable, no-mess cupcake?

That’s exactly what these s’mores cupcakes deliver. I’ve spent years perfecting this recipe, combining a moist graham cracker cupcake base with rich chocolate filling and a billowy marshmallow frosting that gets that irresistible toasted finish. Whether you’re hosting a summer backyard party or just craving a taste of nostalgia on a random Tuesday, these cupcakes bring all the joy of campfire treats without any of the sticky fingers.

Let me walk you through creating these showstopping s’mores cupcakes step by step. I promise they’re easier than you might think, and the reactions you’ll get when serving them are absolutely priceless!

What Makes These S’mores Cupcakes Special

Before we dive into the recipe, let’s talk about what sets these s’mores cupcakes apart from ordinary chocolate cupcakes. First, we’re incorporating actual graham cracker crumbs right into the batter, creating a tender, honey-scented cake that tastes exactly like the base of your favorite campfire treat.

The chocolate element comes in two forms: a surprise chocolate ganache center that stays perfectly molten (hello, gooey goodness!), plus a drizzle on top for that quintessential s’mores look. Finally, instead of simple buttercream, we’re crowning these beauties with a fluffy homemade marshmallow meringue frosting that gets lightly toasted for authentic campfire flavor.

These thoughtful details transform a simple cupcake into an experience that hits all the nostalgic notes of a classic s’more, but in a format that’s perfect for parties, potlucks, or indulgent afternoon treats.

½ cup unsalted butter, softened
1 cup light brown sugar, packed
2 large eggs, room temperature
1 teaspoon vanilla extract
¾ cup milk, room temperature

1 cup granulated sugar
¼ teaspoon cream of tartar
1 teaspoon vanilla extract
Pinch of salt

Additional Garnishes:

6 graham crackers, broken into small pieces
¼ cup chocolate chips, melted for drizzling
Mini chocolate bars (optional)

Essential Equipment

Before diving into this s’mores cupcakes recipe, make sure you have these tools on hand:

Standard 12-cup muffin tin
Cupcake liners
Electric mixer (stand or handheld)
Heat-safe glass bowl for ganache
Piping bag with large round tip
Kitchen torch (or your oven’s broiler)
Cooking thermometer (for the frosting)

Step-by-Step S’mores Cupcakes Recipe

Preparing the Graham Cracker Cupcakes

Preheat and prep: Start by heating your oven to 350°F (175°C) and line your muffin tin with paper liners. This recipe makes 15-16 cupcakes, so you might need to bake in batches.
Mix dry ingredients: In a medium bowl, whisk together the flour, graham cracker crumbs, baking powder, salt, and cinnamon until well combined. The cinnamon might seem like a small addition, but it really enhances that authentic graham cracker flavor!
Cream butter and sugar: In a large bowl, beat the softened butter and brown sugar with an electric mixer until light and fluffy, about 3-4 minutes. Don’t rush this step—it creates the base for a tender crumb.
Add wet ingredients: Beat in the eggs one at a time, then stir in the vanilla extract. The mixture might look a little curdled at this point, but don’t worry—that’s normal!
Combine wet and dry: Gradually add the dry ingredients to the butter mixture, alternating with milk, beginning and ending with the dry ingredients (about 3 additions of dry, 2 of milk). Mix on low speed just until combined after each addition. Be careful not to overmix!
Fill cupcake liners: Divide the batter evenly among the cupcake liners, filling each about ⅔ full. A cookie scoop works perfectly for this.
Bake to perfection: Bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean. The tops should be lightly golden and spring back when gently pressed.
Cool completely: Allow the cupcakes to cool in the pan for 5 minutes, then transfer to a wire rack to cool completely before filling and frosting.

Creating the Chocolate Ganache Center

Heat cream: While the cupcakes are cooling, place chocolate chips in a heat-safe bowl. Heat the heavy cream in a small saucepan until it just begins to simmer (small bubbles form around the edges).
Make ganache: Pour the hot cream over the chocolate chips and let sit for 2-3 minutes. Add the tablespoon of butter, then whisk until smooth and glossy. The butter gives the ganache a beautiful shine and helps it stay soft even when cooled.
Cool slightly: Allow the ganache to cool for about 10 minutes, stirring occasionally. It should thicken slightly but remain pourable.
Create cupcake centers: Once cupcakes are completely cool, use a small knife or cupcake corer to remove a circle from the center of each cupcake, about 1 inch in diameter and 1 inch deep. Save the tops if you’d like!
Fill with ganache: Spoon the chocolate ganache into each cupcake cavity, filling to just below the top. If you saved the cupcake tops, you can place them back on (trimmed if needed) to create a flat surface for frosting.

Whipping Up the Marshmallow Frosting

Prepare a double boiler: Fill a saucepan with about an inch of water and bring to a simmer. Place a heat-safe bowl over the pan, ensuring the bottom doesn’t touch the water.
Combine frosting ingredients: In this bowl, whisk together egg whites, granulated sugar, and cream of tartar.
Heat the mixture: Continuously whisk the mixture over the simmering water until it reaches 160°F on a candy thermometer, or until the sugar is completely dissolved and the mixture feels hot to the touch (about 3-4 minutes).
Whip to stiff peaks: Transfer the mixture to the bowl of a stand mixer fitted with the whisk attachment (or use a hand mixer). Add vanilla extract and a pinch of salt, then beat on high speed until stiff, glossy peaks form and the mixture has cooled to room temperature, about 5-7 minutes.
Transfer to piping bag: Immediately spoon the marshmallow frosting into a piping bag fitted with a large round tip. Work quickly, as this frosting will begin to set.

Assembling Your S’mores Cupcakes

Frost the cupcakes: Pipe a generous swirl of marshmallow frosting on top of each ganache-filled cupcake. Don’t be shy—pile it high for that classic s’more look!
Toast the frosting: Using a kitchen torch, carefully toast the frosting until golden brown in spots, just like a perfectly roasted marshmallow. If you don’t have a torch, place the frosted cupcakes under a broiler for 30 seconds to 1 minute, watching VERY carefully to prevent burning.
Add final touches: While the frosting is still slightly warm, sprinkle with graham cracker pieces. Drizzle with melted chocolate and, if desired, garnish with a small piece of chocolate bar pushed gently into the top.
Let set: Allow the cupcakes to sit for about 15 minutes before serving, giving the garnishes time to set.

Tips for Perfect S’mores Cupcakes Every Time

Getting the Graham Cracker Base Just Right

For the most authentic s’mores cupcakes experience, the graham flavor needs to shine through. Make sure you’re using fresh graham crackers for the crumbs—stale ones lose that distinctive honey-cinnamon flavor. If you want an even more pronounced graham taste, try brushing the baked cupcakes with a little honey thinned with warm water before filling.

Chocolate Filling Variations

While semi-sweet chocolate creates a balanced ganache, feel free to customize based on your preference. Milk chocolate will give you a sweeter, creamier center that kids especially love. For a more sophisticated flavor, try dark chocolate (60-70% cacao). You can even mix in a tablespoon of creamy peanut butter for a twist on the classic s’more!

Marshmallow Frosting Success

This marshmallow frosting can be a little intimidating if you’ve never made it before, but I promise it’s worth the effort! The key is making sure your bowl and beaters are completely free of any grease or fat residue, which can prevent the egg whites from whipping properly. If you’re short on time, you can substitute marshmallow fluff, though the homemade version really does taste noticeably better.

Make-Ahead Options

These s’mores cupcakes are at their absolute best when freshly assembled, but you can prepare components ahead of time:

Bake the cupcakes up to 2 days in advance and store in an airtight container.
Make the ganache up to 3 days ahead and refrigerate. Warm gently before using.
The marshmallow frosting should be made just before assembling, as it sets quickly and doesn’t store well.

Troubleshooting Common S’mores Cupcakes Issues

Sinking Cupcake Centers

If your cupcakes sink in the middle after baking, your oven temperature might be too high. Many ovens run hot, so consider getting an oven thermometer to check. Also, avoid opening the oven during the first 15 minutes of baking, as the sudden temperature change can cause cupcakes to collapse.

Runny Ganache

If your chocolate ganache seems too thin, it may need more time to cool and set. Place it in the refrigerator for 5-10 minute intervals, stirring between each until it reaches a thick but spoonable consistency. Conversely, if it becomes too firm, gently warm it over a pot of simmering water or microwave in 5-second bursts.

Marshmallow Frosting Deflating

If your marshmallow frosting loses volume or becomes grainy, you might not have heated the egg white mixture enough initially. Make sure it reaches at least 160°F to both safely cook the egg whites and properly dissolve the sugar. Also, be sure to beat the mixture until it’s completely cool before attempting to pipe it.

Creative Variations on S’mores Cupcakes

Peanut Butter S’mores Cupcakes

Add 1/3 cup of creamy peanut butter to the cupcake batter for a nutty twist, or swirl peanut butter into the ganache filling. Top with a few chopped peanut butter cups along with the traditional graham cracker pieces.

Cookies and Cream S’mores Cupcakes

Replace half the graham cracker crumbs with crushed chocolate sandwich cookies in the batter. Add some cookie pieces to the ganache filling for a surprise crunch in the center.

Salted Caramel S’mores Cupcakes

Drizzle the inside of the cupcake cavity with salted caramel sauce before adding the chocolate ganache. Top the toasted marshmallow frosting with an additional drizzle of caramel and a sprinkle of flaky sea salt.

Seasonal S’mores Cupcake Adaptations

Summer: Add fresh raspberry puree to the ganache for a fruity twist
Fall: Incorporate pumpkin spice into the graham cracker base
Winter: Add a drop of peppermint extract to the chocolate ganache
Spring: Mix lemon zest into the cupcake batter for brightness

Storing and Serving Your S’mores Cupcakes

These s’mores cupcakes are best enjoyed the same day they’re assembled, when the contrast between the tender cake, gooey filling, and freshly toasted marshmallow frosting is at its peak. However, they can be stored in an airtight container at room temperature for up to 2 days.

Refrigeration isn’t recommended as it will firm up the ganache and change the texture of the frosting. If you need to make them further in advance, I suggest preparing the components separately and assembling closer to serving time.

For the ultimate presentation, serve these s’mores cupcakes alongside mugs of hot chocolate in winter or cold milk in summer. They make a showstopping dessert for birthday parties, summer barbecues, or even as an elevated camping trip treat!

Frequently Asked Questions About S’mores Cupcakes

Can I make these s’mores cupcakes without a kitchen torch?

Absolutely! While a kitchen torch gives you the most control over toasting the marshmallow frosting, your oven’s broiler works well too. Place the frosted cupcakes on a baking sheet, position them about 6 inches from the broiler element, and watch them like a hawk—they’ll toast in 30-60 seconds and can burn quickly.

How can I make this s’mores cupcakes recipe gluten-free?

To make gluten-free s’mores cupcakes, substitute the all-purpose flour with a 1:1 gluten-free baking blend. For the graham cracker component, use gluten-free graham crackers or make a crust from gluten-free cookies mixed with a bit of honey and cinnamon to mimic that graham flavor.

Can I use marshmallow fluff instead of making the frosting from scratch?

Yes! While homemade marshmallow frosting has a superior texture and flavor, store-bought marshmallow fluff can be a convenient shortcut. Simply spread it over the cupcakes and toast as directed. You might want to stabilize it slightly by beating 4 ounces of softened cream cheese with 1 cup of marshmallow fluff.

Why did my chocolate ganache separate or become grainy?

Ganache typically separates when it’s overheated or if liquid is added too quickly. To fix a broken ganache, warm it gently while vigorously whisking, or try adding a splash of warm heavy cream and stirring until smooth again.

Can I make a mini version of these s’mores cupcakes for a party?

Definitely! This s’mores cupcakes recipe adapts beautifully to mini cupcakes. Use a mini muffin tin lined with small cupcake liners and reduce the baking time to about 10-12 minutes. For filling, use a smaller coring tool or the end of a piping tip to create tiny wells for the ganache.
