S’mores Cupcakes Recipe

I made these S’mores Cupcakes Recipe over the weekend, and they brought all the cozy campfire magic right into my kitchen without needing an outdoor fire pit. The combination of a tender graham cracker cupcake base, a rich dark chocolate ganache core, and a fluffy toasted marshmallow frosting is absolute perfection.

I love how using a kitchen torch to toast the marshmallow top gives you that authentic, golden campfire finish and aroma. They are rich, nostalgic, and guaranteed to impress both kids and adults at any gathering. Trust me, once you bite into that molten chocolate center paired with gooey toasted marshmallow, these decadent cupcakes will become an instant favorite just like they did for me.

Ingredients

Using graham cracker crumbs directly in the flour blend and real marshmallow fluff ensures an authentic s’mores flavor from crumb to top.

• 1 cup all-purpose flour (provides structure for a soft, delicate cupcake crumb)
• 1/2 cup fine graham cracker crumbs (folded into the dry ingredients to infuse authentic graham crust flavor throughout the cake)
• 1 teaspoon baking powder (helps the cupcakes rise into light, even domes)
• 1/4 teaspoon baking soda (works with the sour cream to keep the crumb ultra-moist)
• 1/4 teaspoon salt (balances the rich sweetness of the sugars and marshmallow)
• 1/2 cup unsalted butter, softened to room temperature (creams smoothly for a rich cake foundation)
• 1/2 cup granulated sugar (adds light sweetness to complement the graham flavor)
• 1/4 cup dark brown sugar, packed (adds deep caramel moisture and warmth)
• 2 large eggs, room temperature (binds the batter and builds structure)
• 1 teaspoon pure vanilla extract (enhances the warm, sweet bakery notes)
• 1/3 cup sour cream or whole milk, room temperature (creates an exceptionally tender cupcake texture)
• 1/2 cup dark chocolate chips + 1/4 cup heavy cream (melted together to create the rich chocolate ganache center)
• 1 cup unsalted butter, softened (for the marshmallow buttercream base)
• 1.5 cups powdered sugar (sweetens and stabilizes the frosting)
• 1 jar (7 oz) marshmallow fluff or marshmallow creme (delivers that iconic gooey marshmallow top)
• Whole graham crackers and mini chocolate bars (for garnish)

Note: This recipe yields 12 campfire-inspired cupcakes.

How to Make S’mores Cupcakes?

Follow these simple, step-by-step instructions to bake graham cracker cupcakes filled with chocolate ganache and topped with toasted marshmallow frosting.

Make and Bake the Cupcakes

Preheat your oven to 350°F (175°C) and line a 12-cup muffin pan with paper liners. In a medium bowl, whisk together the flour, graham cracker crumbs, baking powder, baking soda, and salt. In a large bowl, beat the softened butter, granulated sugar, and brown sugar for 2 minutes until light and fluffy. Add the eggs, vanilla, and sour cream, beating until smooth. Gradually mix in the dry ingredients on low speed until combined. Divide batter into liners and bake for 16 to 18 minutes until a toothpick inserted comes out clean, then cool completely.

Prepare Ganache and Core Cupcakes

Gently heat the dark chocolate chips and heavy cream in a heat-proof bowl in the microwave in 15-second intervals, stirring until smooth and glossy. Use a cupcake corer or small paring knife to remove a 1-inch deep center from each cooled cupcake. Spoon or pipe the rich chocolate ganache filling generously into the hollowed centers.

Whip Frosting, Toast, and Serve

Beat 1 cup of softened butter in a mixing bowl for 2 minutes until pale and creamy. Add the powdered sugar and mix until smooth, then fold in the jar of marshmallow fluff, beating on high speed for 2 minutes until light and fluffy. Pipe tall swirls of frosting over the filled cupcakes, use a culinary torch to lightly brown the edges, and garnish with a graham cracker square and mini chocolate bar slice before serving.

Additional Tips for Making this Recipe Better

Here are a few personal tricks I rely on to make sure these campfire cupcakes turn out camera-ready every time.

• I always let the chocolate ganache cool for 5 minutes before filling so it stays thick inside the core rather than soaking into the cake crumb.
• I highly recommend using a kitchen torch to toast the frosting right before serving rather than using the oven broiler, which can melt the butter base quickly.
• I like to save the cut-out cake tops and trim them down to press gently back over the chocolate filling before frosting to seal the ganache inside cleanly.

How to Serve S’mores Cupcakes?

Display these showstopping cupcakes on a rustic wooden board or platter to highlight their golden toasted peaks and chocolate garnishes. Place a small piece of dark chocolate bar and a toasted graham cracker triangle into the side of each piped marshmallow peak for a dramatic visual finish. These fun cupcakes serve as the ultimate centerpieces for summer barbecues, outdoor bonfire parties, camping trips, or cozy fall gatherings.

Make Ahead and Storage

Proper storage keeps the chocolate ganache rich and the marshmallow frosting soft and fluffy.

Storage

Store assembled cupcakes in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 4 days. If refrigerated, bring them to room temperature for 20 minutes before serving so the cake base softens.

Freezing

You can freeze un-filled, unfrosted baked cupcakes in a freezer-safe container for up to 2 months. Thaw at room temperature, then fill, frost, and toast fresh right before serving.

Reheating

These cupcakes are designed to be enjoyed at room temperature. Heating in a microwave is not recommended once frosted, as the marshmallow buttercream will melt completely.
