KEY INGREDIENTS IN GOOEY CHOCOLATE S’MORES CUPCAKES
Before we dive into the step-by-step instructions, let’s talk about the star players that make these cupcakes irresistible. Each component has a specific role, from structure and sweetness to that unmistakable s’mores crunch and gooey finish.
- All-purpose flour: The backbone of the cupcake, providing structure and a tender crumb when sifted with the other dry ingredients.
- Granulated sugar: Sweetens the batter and helps create a moist texture by trapping air during mixing.
- Unsweetened cocoa powder: Delivers deep chocolate flavor and rich color, intensifying the dessert experience.
- Baking powder: A leavening agent that ensures your cupcakes rise evenly, giving them a light, fluffy texture.
- Baking soda: Works in tandem with the acidic buttermilk to boost lift and create tiny air pockets for a tender cake.
- Salt: Enhances and balances the sweetness while rounding out the chocolate notes.
- Buttermilk: Adds moisture and a subtle tang that complements the rich cocoa, keeping the crumb soft.
- Vegetable oil: Contributes to a decadent, moist texture that stays fresh longer than butter-based cakes.
- Egg: Binds all ingredients together, lending structure and a glossy finish.
- Vanilla extract: Elevates and brightens the overall flavor profile, making every ingredient sing.
- Boiling water: Intensifies the cocoa’s richness and thins the batter for a smooth, pourable consistency.
- Graham cracker squares: Form a crunchy, sweet base reminiscent of traditional s’mores crust.
- Large marshmallows: Toasted on top for that signature gooey, golden finish.
- Chocolate chips: Melt into pockets of pure chocolate bliss, adding bursts of gooey richness.

HOW TO MAKE GOOEY CHOCOLATE S’MORES CUPCAKES
Ready to transform these simple ingredients into a show-stopping dessert? Follow these clear, detailed steps to achieve perfectly baked cupcakes with that classic s’mores finish.
1. Preheat the oven to 350°F (175°C) and line a 12-cup muffin tin with cupcake liners. Ensuring the oven reaches the correct temperature before baking guarantees an even rise and consistent crumb throughout.
2. In a large mixing bowl, sift together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. Sifting removes lumps and incorporates air, resulting in a lighter, more uniform batter.
3. In another bowl, whisk the buttermilk, vegetable oil, egg, and vanilla extract until well combined. This wet mixture brings moisture and richness, making every bite tender.
4. Gradually add the wet ingredients to the dry ingredients, mixing until the batter is smooth. Take care not to overmix—just enough to combine for a soft, fluffy texture.
5. Stir in the boiling water until fully incorporated. The thin batter is normal; it helps produce a moist, fudgy crumb.
6. Place a graham cracker square at the bottom of each cupcake liner. This creates a delightful crunch that echoes the classic campfire treat.
7. Pour a generous scoop of the chocolate batter over each graham cracker until they are 2/3 full. This ensures space for the cupcakes to rise without spilling over.
8. Add a few chocolate chips on top of the batter in each cup. These will melt into gooey pockets of rich chocolate as they bake.
9. Bake for 18–20 minutes or until a toothpick inserted into the center of a cupcake comes out clean. Watch the color—cupcakes should look set but still moist.
10. Remove cupcakes from the oven and turn on the broiler setting. This step readies the oven for the perfect marshmallow toast.
11. Place 2 marshmallows on top of each cupcake and return to the oven. Watch carefully and broil until the marshmallows are golden brown, about 1–2 minutes. They should puff and develop a toasted exterior without burning.
12. Remove and allow cupcakes to cool slightly. Optionally, sprinkle more graham cracker crumbs on top or drizzle with melted chocolate for an extra touch of elegance.
SERVING SUGGESTIONS FOR GOOEY CHOCOLATE S’MORES CUPCAKES
After investing your time and love into these cupcakes, you’ll want to present them in a way that wows guests and elevates the overall experience. Whether you’re serving them at a cozy family gathering or a festive party, small touches can make a big difference.

Pairing them with complementary sides and garnishes enhances both flavor and visual appeal. Below are four creative serving ideas that bring out the best in these gooey delights.
- Serve on a rustic wooden platter with a sprinkling of extra graham cracker crumbs around the edges, creating a campfire-inspired display.

- Drizzle a bit of salted caramel sauce over the toasted marshmallows and finish with a light sprinkle of coarse sea salt to contrast sweet and salty flavors.

HOW TO STORE GOOEY CHOCOLATE S’MORES CUPCAKES
Ensuring your cupcakes remain moist and flavorful after baking is key to enjoying them over several days. Proper storage helps maintain the gooey marshmallow topping without turning it soggy and preserves the tender chocolate crumb. Whether you have leftovers or want to prep these treats in advance, here are some reliable methods to keep them tasting just-baked fresh.
- Room temperature: Store cooled cupcakes in an airtight container at room temperature for up to 2 days. This method keeps marshmallows fluffy and prevents the cake from drying out.
- Refrigeration: Place cupcakes in a sealed container and refrigerate for up to 3 days. Bring them back to room temperature before serving to soften the marshmallow and restore that fresh-baked feel.
- Freezing: Wrap each cupcake individually in plastic wrap, then place them in a freezer-safe bag or container. Freeze for up to 2 months. Thaw overnight in the refrigerator or for a few hours at room temperature.
- Re-crisping the top: If the marshmallow loses its golden hue after storage, briefly place cupcakes under a low broiler for 20–30 seconds to refresh the toasted finish. Watch closely to avoid burning.
