Cooling Time: 1 hour
Total Time: Approximately 1 hour 45 minutes
Ingredients
For the Brownies
- 1/2 cup unsalted butter, melted
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/3 cup unsweetened cocoa powder
- 1/2 cup all-purpose flour
- 1/4 teaspoon salt

How to Make Marshmallow Ghost Brownies
Step 1: Make the Brownies
Preheat the oven to 350°F and line an 8 × 8-inch baking pan with parchment paper.
In a large mixing bowl, whisk together the melted butter and sugar.
Add the eggs and vanilla extract and mix until smooth.
Stir in the cocoa powder, flour, salt, and baking powder until just combined.
Fold in the mini chocolate chips if you’re using them.
Spread the batter evenly into the prepared baking pan.
Bake for approximately 25–30 minutes, or until the edges are set and a toothpick inserted near the center comes out with a few moist crumbs.
Allow the brownies to cool completely before decorating.
Step 2: Cut the Brownies
Once the brownies have cooled, lift them out of the pan using the parchment paper.
Cut into 16 even squares and arrange them on a serving platter or parchment-lined tray.
Step 3: Add the White Frosting
Place the white vanilla frosting in a microwave-safe bowl.
Warm it in the microwave for about 5–10 seconds at a time, stirring between intervals, until it’s soft enough to spread and gently drip over the edges. Don’t overheat it.
Spoon a generous amount of frosting onto the center of each brownie.
Gently spread it outward, allowing a little frosting to drip over the sides. This creates the flowing, melted ghost appearance.
Step 4: Add the Marshmallow Ghosts
Place one large marshmallow upright in the center of each frosted brownie.
Press it gently into the frosting so it stays in place.
The marshmallow becomes the ghost’s head, while the white frosting underneath creates its flowing body.
Step 5: Decorate the Ghost Faces
Using black decorating icing, pipe two small oval eyes onto the front of each marshmallow.
Add one larger oval underneath the eyes to create the ghost’s surprised open mouth.
Repeat with the remaining marshmallows.
Allow the frosting to set slightly before serving.
Tips for Making the Cutest Ghost Brownies
Use large marshmallows. Regular large marshmallows work perfectly for creating the little ghost heads.
Let the brownies cool completely. Warm brownies can cause the frosting to melt too much and run off the sides.
Don’t overheat the frosting. You want it soft enough to spread and drip naturally, but not so thin that it runs completely off the brownies.
Make different ghost expressions. Give some ghosts bigger eyes or slightly different mouths to make each one unique.
Use boxed brownies for a shortcut. A boxed brownie mix works just as well if you want to keep this Halloween dessert extra simple.
Why You’ll Love These Halloween Brownies
These Marshmallow Ghost Brownies are such a fun combination of rich chocolate and sweet vanilla frosting.
The brownies are fudgy and chocolatey, while the marshmallow adds a soft, fluffy bite. The white frosting makes everything extra sweet and gives the ghosts their adorable melted appearance.
They’re also easy to make in large batches, which makes them a great choice for Halloween parties and dessert tables.
Can I Make Marshmallow Ghost Brownies Ahead of Time?
Yes! You can bake the brownies a day ahead and store them in an airtight container.
For the best appearance, add the frosting and marshmallow ghosts the day you plan to serve them.
You can also decorate the marshmallow faces ahead of time and let the black icing dry before assembling the brownies.
How to Store Marshmallow Ghost Brownies
Store the decorated brownies in a single layer in an airtight container at room temperature for up to 2 days, provided your frosting is shelf-stable.
Keep them in a cool location so the frosting doesn’t become too soft.
For the prettiest presentation, these brownies are best enjoyed the day they’re decorated.

Jennie’s Thoughts
I think these Marshmallow Ghost Brownies turned out absolutely adorable! I especially love how the white frosting drips over the sides of the brownies and makes it look like the little marshmallow ghosts are floating in a puddle of frosting.
The faces are my favorite part. Just two little black eyes and an open mouth give each marshmallow so much personality!
I also love that these don’t require any fancy decorating skills. You’re really just making a pan of brownies, adding some frosting, and decorating a few marshmallows. It’s such an easy way to turn ordinary brownies into something special for Halloween.
I think these would be so cute served alongside my Floating Ghost Halloween Brownies. One has the flat ghost icing transfers, and the other has these adorable little marshmallow ghosts sitting on top. Together, they’d make such a fun Halloween brownie platter!
