Ingredients

Graham Cracker Crumbs: These form the crisp, buttery base that mimics the classic s’mores campfire crunch.

Butter (melted): Mixed with the graham cracker crumbs, it binds the crust and adds rich flavor.

Granulated Sugar: Enhances sweetness and helps in setting the graham crust.

All-purpose Flour: Provides structure to the chocolate cupcake portion.

Unsweetened Cocoa Powder: Essential for that deep, chocolatey flavor.

Baking Powder & Baking Soda: Together, they give the cupcakes their light, fluffy rise.

Salt: Balances the sweetness and enhances all the flavors.

Eggs: Act as a binder and give the cupcakes a soft, tender crumb.

Buttermilk: Adds moisture and a slight tang, making the chocolate rich and smooth.

Vegetable Oil: Keeps the cupcakes moist for days.

Vanilla Extract: Deepens the flavor, adding a warm, comforting undertone.

Boiling Water: Intensifies the cocoa flavor and ensures a luscious batter.

Marshmallow Creme or Large Marshmallows: These are the gooey surprise at the center of each cupcake.

Chocolate Frosting: The final touch — creamy and indulgent, it ties everything together.

How to Make Decadent Chocolate S’mores Cupcakes with Gooey Marshmallow Center

Step 1: Make the Graham Cracker Crust
Preheat your oven to 350°F (175°C). Line a muffin tin with cupcake liners. Mix graham cracker crumbs, melted butter, and sugar in a bowl until the texture is like wet sand. Spoon a heaping tablespoon into each liner, press down firmly, and bake for 5 minutes. Let cool slightly.

Step 2: Prepare the Chocolate Cupcake Batter
In a large bowl, whisk together the flour, cocoa powder, baking powder, baking soda, salt, and sugar. In another bowl, whisk eggs, buttermilk, vegetable oil, and vanilla extract. Combine wet and dry ingredients, then stir in boiling water until the batter is thin and smooth.

Step 3: Fill and Bake the Cupcakes
Spoon a bit of chocolate batter over the baked graham crusts, then drop in a generous teaspoon of marshmallow creme or one large marshmallow. Cover with more chocolate batter until liners are 3/4 full. Bake for 18-20 minutes or until a toothpick inserted comes out mostly clean (avoid poking the marshmallow).

Step 4: Cool and Frost
Allow cupcakes to cool in the pan for 5 minutes, then transfer to a wire rack to cool completely. Once cool, generously frost with your favorite chocolate frosting and garnish with mini marshmallows or graham cracker crumbs if desired.

Recipe Variations and Possible Substitutions

If you’re out of buttermilk, you can easily substitute it with a mix of milk and lemon juice or vinegar. Let it sit for a few minutes to curdle before using. For a gluten-free version, use your favorite 1:1 gluten-free flour blend and certified gluten-free graham crackers. You can also switch up the center — try using a square of milk chocolate or a flavored marshmallow for an unexpected twist. Prefer something less sweet? Opt for a dark chocolate frosting or skip the frosting and top with a roasted marshmallow instead.

Serving and Pairing Suggestions

These cupcakes are fantastic on their own but even better when served slightly warm to get that marshmallow gooeyness back. Pair with a tall glass of cold milk, a hot espresso, or even a cozy mug of hot cocoa. They’re also great for celebrations: dress them up with decorative cupcake liners or sparkly sprinkles to make them party-ready.

Storage and Reheating Tips

Store the cupcakes in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. To reheat and revive the gooey center, microwave each cupcake for about 10-12 seconds. If frozen, allow them to thaw at room temperature before reheating. The frosting holds up well, but for best texture, re-frost lightly after thawing if needed.
