These Halloween s’mores cupcakes turn the familiar campfire trio into a party-friendly bake: a buttery graham base, moist chocolate cake, and a tall marshmallow frosting shaped like a friendly ghost. Two chocolate dots finish the look without demanding advanced piping skills.
The components are deliberately balanced. The crust stays thin and crisp, the cupcake remains soft, and the frosting is firm enough to hold a rounded ghost shape at room temperature for serving.
Why this cupcake format works
A small graham layer gives every bite a toasted-cookie foundation without making the wrapper greasy. Hot coffee or water blooms the cocoa in the batter. Marshmallow creme stabilizes the buttercream and creates the recognizable s’mores flavor without a torch.
Ingredient notes
Use fine graham crumbs so the bases compact evenly. Natural or Dutch-process cocoa both work here because the batter contains enough baking soda and acidity from buttermilk. Room-temperature butter is essential for smooth ghost frosting.
Simple assembly
Press a spoonful of graham mixture into each liner, add chocolate batter, and bake until the tops spring back. Once completely cool, pipe one tall spiral of marshmallow frosting from a wide round tip. Add two miniature chocolate-chip eyes just before the frosting sets.
Success tips
- Fill every liner with the same amount so the cupcakes finish together.
- Cool the cakes fully before frosting; even gentle warmth will soften the ghost shape.
- If the frosting feels loose, chill it for 10 minutes rather than adding excessive sugar.
- Keep the chocolate eyes small so the faces remain clear and friendly.
Substitutions and variations
Replace buttermilk with milk mixed with lemon juice as listed in the recipe. Chocolate wafer crumbs can replace the graham base for a darker look. For a different palette, add a restrained orange sprinkle border around the frosting.
Storage and make-ahead
Bake the cupcakes one day ahead and store them airtight at room temperature. Frosted cupcakes keep in the refrigerator for up to three days; let them stand at room temperature for 20 minutes before serving. Do not freeze the finished ghost decorations.
Frequently asked questions
Do I need a piping bag?
A zip-top bag with one corner cut can work, although a large round piping tip makes the smoothest ghost.
Can children help decorate?
Yes. An adult can pipe the frosting, then children can place the miniature chocolate-chip eyes.

Description
Moist chocolate cupcakes over a graham crust, finished with stable marshmallow-creme ghost frosting.
Ingredients
- 3/4 cup (85 g) fine graham cracker crumbs
- 3 tbsp (42 g) unsalted butter, melted
- 1 tbsp (12 g) granulated sugar
- 1 cup (120 g) all-purpose flour
- 3/4 cup (150 g) granulated sugar
- 1/3 cup (28 g) unsweetened cocoa powder
- 3/4 tsp (4 g) baking soda
- 1/2 tsp (2 g) baking powder
- 1/4 tsp (1.5 g) fine salt
- 1 large egg (about 50 g without shell)
- 1/2 cup (120 ml) buttermilk
- 1/3 cup (80 ml) neutral oil
- 1 tsp (5 ml) vanilla extract
- 1/2 cup (120 ml) hot coffee or hot water
- 1/2 cup (113 g) unsalted butter, softened
- 1 cup (120 g) marshmallow creme
- 2 cups (240 g) powdered sugar
- 1 tsp (5 ml) vanilla extract for frosting
- 1–2 tbsp (15–30 ml) heavy cream
- 24 miniature chocolate chips (about 12 g), for eyes
Instructions
- Heat the oven to 350°F (175°C). Line one 12-cavity standard muffin pan with dark paper liners.
- Mix the graham crumbs, melted butter, and 1 tbsp (12 g) sugar. Divide among the liners and press into thin level bases.
- Whisk the flour, 3/4 cup (150 g) sugar, cocoa, baking soda, baking powder, and salt in a bowl.
- Whisk the egg, buttermilk, oil, and vanilla separately. Add to the dry mixture, then slowly whisk in the hot coffee until smooth; the batter will be thin.
- Divide the batter evenly over the graham bases, filling each liner about two-thirds full. Bake 18–21 minutes, until the tops spring back and a tester shows a few moist crumbs. Cool completely.
- Beat the softened butter for 2 minutes. Beat in the marshmallow creme, powdered sugar, and vanilla. Add cream 1 tsp (5 ml) at a time until smooth but firm.
- Pipe one tall rounded spiral of frosting on each cupcake using a large round tip. Press two miniature chocolate chips into each ghost for eyes.
- Chill for 10 minutes to set the shapes, then serve at cool room temperature.
Notes
If the room is warm, refrigerate the frosting for 10 minutes before piping. Keep finished cupcakes chilled until shortly before serving.
