Ingredients You’ll Need
For the Graham Cracker Base
- 1 ½ cups crushed graham crackers
- ¼ cup granulated sugar
- 6 tbsp melted butter
For the Cupcakes
- 1 cup all-purpose flour
- ½ cup unsweetened cocoa powder
- 1 cup granulated sugar
- 1 tsp baking powder
- ½ tsp baking soda
- ½ tsp salt
- ½ cup vegetable oil
- 2 large eggs
- 1 tsp vanilla extract
- ½ cup buttermilk
- ½ cup hot water
For the Ghost Topping
- 1 jar marshmallow creme (or 2 cups mini marshmallows melted)
- ½ cup powdered sugar (to stiffen, if needed)
- Melted chocolate or black decorating gel (for faces)
Step-by-Step Instructions
Step 1: Prepare the Graham Cracker Base
- Preheat oven to 350°F (175°C). Line a muffin tin with cupcake liners.
- Mix graham cracker crumbs, sugar, and melted butter until crumbly.
- Spoon about 1 tablespoon into each cupcake liner and press down firmly to form a crust.
Step 2: Make the Cupcakes
- In a large bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt.
- Add oil, eggs, and vanilla. Mix until smooth.
- Stir in buttermilk and hot water—batter will be thin, but that’s perfect for moist cupcakes.
- Pour over graham cracker crusts, filling liners about ⅔ full.
- Bake for 18–20 minutes, until a toothpick comes out clean. Cool completely before decorating.
Step 3: Create the Ghostly Marshmallow Topping
- Spoon marshmallow creme into a piping bag fitted with a round tip.
- Pipe tall ghost shapes on top of each cooled cupcake. If marshmallow creme is too runny, beat it with powdered sugar until slightly stiffer.
- Use melted chocolate or black gel to dot two eyes and a spooky mouth on each ghost.
Tips & Variations
- Toasted Ghosts: Lightly torch the marshmallow topping with a kitchen torch for a smoky, campfire look.
- Stuffed Cupcakes: Add a piece of chocolate or a mini marshmallow in the center of each cupcake before baking for a hidden surprise.
- Kid-Friendly Swap: Use large marshmallows instead of piped creme—stick one on top, then draw faces.
- Party Presentation: Serve on a platter lined with crushed graham crackers for a “graveyard dirt” effect.
Storage & Make-Ahead
- Room Temperature: Store in an airtight container for up to 2 days.
- Refrigerator: Store for 4–5 days, though marshmallow topping may firm up.
- Freezer: Freeze undecorated cupcakes for up to 2 months. Add ghost topping after thawing.
FAQs
Can I use boxed cake mix instead?
Yes! A chocolate or devil’s food mix works perfectly if you’re short on time.
Do I need marshmallow creme, or can I use whipped cream?
Whipped cream won’t hold its ghostly shape. Marshmallow creme or melted marshmallows are best.
How do I make the faces neat?
A toothpick dipped in melted chocolate works great for fine details.
Final Bite
These Ghostly S’mores Cupcakes are the perfect way to bring a little spooky fun to the table without sacrificing flavor. Every bite is a mix of graham cracker crunch, rich chocolate cake, and gooey marshmallow—just like your favorite campfire treat, dressed up for Halloween.
