This recipe for S’more Muffins became a weekend ritual in my kitchen the first time I tried to bottle the magic of a campfire treat into a muffin tin. I remember the evening clearly: a rainy Saturday, the smell of graham crackers crushed on the counter, and a child-sized pile of marshmallows waiting impatiently to be dropped into batter. The result was unexpectedly tender — a crumb that felt almost cake-like, a buttery graham warmth, little pockets of molten chocolate, and marshmallows that browned on top like tiny campfires. They’re equally at home at breakfast, as an after-school snack, or warmed and split for an indulgent dessert.

I first developed this version when I wanted something faster than s’mores on sticks but with the same textural contrast: crisp top, soft interior, and gooey centers. The trick is folding miniature marshmallows into a muffin batter that’s not overworked and topping each cup with a few extra marshmallows so they caramelize in the oven. These are casual to make, forgive small mistakes, and reward you with nostalgic flavor and a crowd-pleasing presentation. Over the years I’ve refined the batter so the crumb stays moist for a day or two and the marshmallows keep their pillowy charm rather than becoming purely rubbery.

Ingredients

• All-purpose flour: Use 1 1/2 cups (measured by spooning flour into the cup and leveling) for structure. White wheat flour will work but produces a denser crumb; I prefer standard all-purpose for a tender, light texture.
• Graham cracker crumbs: 1/2 cup (about 4 full sheets, crushed). Graham crumbs contribute the classic s’mores flavor and a faint crunch. For consistent texture, pulse whole sheets in a food processor or place in a resealable bag and crush with a rolling pin.
• Brown sugar: 1/4 cup packed. The molasses in brown sugar deepens the flavor and keeps the crumb moist; light or dark both work, but dark gives a more caramel note.
• Baking soda and salt: 1 teaspoon baking soda and 1/2 teaspoon salt balance lift and flavor. Measure carefully — baking soda gives rise and the classic muffin domes.
• Egg: 1 large egg, at room temperature. It binds and gives the crumb lift; a cold egg can tighten batter, so allow it to sit on the counter briefly.
• Buttermilk: 1 1/2 cups. Buttermilk adds acidity and tang that react with baking soda for tender crumb; if you don’t have buttermilk, make a quick substitute with 1 1/2 cups milk plus 1 1/2 tablespoons lemon juice or vinegar and let sit 5 minutes.
• Canola oil: 1/4 cup. Neutral-flavored oil keeps the muffins moist and creates a softer texture than melted butter; use vegetable or sunflower oil as alternatives.
• Vanilla extract: 1 teaspoon for aroma and depth. Pure vanilla is worth the small investment here; it brightens the chocolate and marshmallow notes.
• Semisweet chocolate chips: 3/4 cup (mini chips recommended). The smaller chips disperse evenly through the batter and create gooey pockets rather than large melty blobs.
• Mini marshmallows: 1 1/4 cups total, divided. Fold in 1 cup into the batter for pockets of marshmallow and reserve 1/4 cup (about 2–3 per muffin) to top each cup for toasty crowns.
• Cooking spray: To coat the muffin tin lightly so tops release cleanly and the graham crumbs don’t stick.

Instructions

Preheat and prepare: Set the oven to 375°F (190°C). Generously spray a 12-cup muffin tin with cooking spray or line with paper liners and spray the liners — the oil helps the marshmallows release without tearing the tops. Allow the oven to fully reach temperature so the muffins begin rising immediately when placed inside. Mix dry ingredients: In a large bowl whisk together 1 1/2 cups all-purpose flour, 1/2 cup graham cracker crumbs, 1/4 cup packed brown sugar, 1 teaspoon baking soda, and 1/2 teaspoon salt. Whisking distributes the leavening and prevents clumps so you get even lift in each muffin. Combine wet ingredients: In a separate bowl beat 1 large egg lightly, then whisk in 1 1/2 cups buttermilk, 1/4 cup canola oil, and 1 teaspoon vanilla extract until uniform. Room-temperature ingredients emulsify more readily, producing a smoother batter. Fold wet into dry: Pour the wet mixture into the dry and stir gently with a spatula until just combined; a few streaks of flour are fine. Overmixing develops gluten and yields a tougher muffin. Fold in 3/4 cup chocolate chips and 1 cup miniature marshmallows, distributing them with light strokes so they don’t deflate the batter. Fill cups and top: Divide batter evenly among the 12 prepared cups (about 1/4 to 1/3 cup batter per cup). Top each with 2–3 miniature marshmallows so they sit on the surface and caramelize in the oven into a golden toast. Bake and test: Bake at 375°F for 13 to 15 minutes. A wooden toothpick inserted in the center should come out clean or with a few moist crumbs but not raw batter. Watch the tops during the last minutes; marshmallows will puff and color quickly. If the marshmallows brown too fast, tent loosely with foil for the final minute. Cool and serve: Cool the pan on a wire rack for 10 minutes, then gently remove the muffins and cool completely on the rack for the best texture. Warm slightly before serving to revive the marshmallow and chocolate if they’ve cooled completely.

Storage Tips

Store cooled muffins in an airtight container at room temperature for up to 48 hours to preserve marshmallow texture; refrigerating will extend life to 3 days but can firm the marshmallow tops. For longer storage, wrap each muffin individually in plastic wrap and place in a freezer-safe bag for up to 3 months. Reheat frozen muffins in a preheated 300°F oven for 8–10 minutes or microwave for 20–30 seconds on medium power — be cautious with microwaves, as marshmallows can over-expand and become rubbery quickly.

Ingredient Substitutions

For a dairy-free version, swap buttermilk for a mixture of unsweetened almond or oat milk and 1 1/2 tablespoons vinegar per 1 1/2 cups and use dairy-free chocolate chips. To deepen flavor, replace the canola oil with 1/4 cup melted unsalted butter (cooled) for a richer mouthfeel. If you need gluten-free, use a 1:1 gluten-free flour blend and check that graham crumbs are labeled gluten-free — texture will be slightly different and may be crumblier. For lower sugar, reduce the brown sugar by 2 tablespoons and use dark chocolate chips to maintain balance.

Serving Suggestions

Serve warm with a smear of salted butter or a small scoop of vanilla ice cream for a dessert twist. For breakfast, pair with plain Greek yogurt and fresh berries to cut the sweetness. These muffins are great on a brunch board alongside fresh fruit, toasted nuts, and coffee. Garnish with a light dusting of finely crushed graham crumbs or a single halved toasted marshmallow for an elevated presentation.

Cultural Background

The s’more is a North American campfire classic dating back to the early 20th century, embodying outdoor cooking and communal enjoyment. Translating that combination of graham cracker, chocolate, and toasted marshmallow into a baked good preserves the familiar flavors while adapting them for year-round kitchens. This baked interpretation nods to American picnic culture and modern comfort-food baking trends that prioritize portability and nostalgia.

Seasonal Adaptations

In colder months, add a pinch of cinnamon or a tablespoon of molasses to the batter for warm spice notes. For summer gatherings, mix in 1/2 cup chopped fresh strawberries to brighten the profile, or use white chocolate chips with lemon zest for a seasonal twist. During holidays, top with a small drizzle of salted caramel or sprinkle flaky sea salt over warm muffins to balance sweetness.

Meal Prep Tips

To prepare ahead for a week of snacks, bake a double batch and freeze half. Portion into single-serve containers or baggies so you can thaw only what you need. When reheating, use low oven heat to warm through without over-browning the marshmallow; a toaster oven is ideal for single servings. Label freezer bags with the date and reheat instructions so guests or family members can serve themselves easily.

These S’more Muffins are a little bit playground, a little bit bakery — they capture the best parts of childhood treats in a format adults still love. Share them warm, and expect compliments and requests for the recipe.
