Ghostly caramel marshmallow brownies bring together rich fudgy cocoa brownies with gooey caramel and puffy marshmallow "ghosts" for a festive treat perfect for Halloween or any fun celebration. These brownies balance indulgent flavors with playful presentation to delight kids and adults alike.
I first made these for a chilly October evening when a group of neighborhood kids came by, and everyone loved the spooky twist on a classic dessert. They have since become a go-to for any party where you want to impress with both taste and creativity. I remember my niece’s face lighting up the first time she helped me assemble the marshmallow ghosts—it made baking feel like a shared adventure rather than a chore.
Ingredients
- 1 cup unsalted butter: melted for smooth richness — use good quality for best flavor
- 2 cups granulated sugar: to sweeten the dense chocolate base
- 4 large eggs: to bind and give structure
- 1 tablespoon pure vanilla extract: enhances all the other flavors naturally
- 1 cup all-purpose flour: provides structure while keeping the texture tender
- 1 cup unsweetened cocoa powder: for deep chocolate intensity — choose Dutch processed for mellow earthiness
- Half teaspoon salt: balances out sweetness and intensifies cocoa notes
- Half teaspoon baking powder: to give a slight lift without losing fudginess
- Half cup caramel sauce: adds luscious swirls of sticky sweetness — warm slightly if too thick for easier swirling
- Large marshmallows: one per brownie to create the puffy ghost tops — fresh and soft are best
- Mini semi-sweet chocolate chips: for the ghost eyes — the tiny size helps mimic eyes perfectly
- Powdered sugar: for a ghostly dusting that adds subtle sweetness and spookiness
- Extra caramel sauce: for drizzling a dramatic finishing touch
Instructions
- Prepare the Brownie Batter:
- Preheat your oven to 350 degrees Fahrenheit or 175 degrees Celsius. Generously grease and line a 9 by 13 inch baking pan with parchment paper to ensure the brownies lift easily later. In a large mixing bowl, whisk the melted butter and granulated sugar together vigorously until glossy—this step helps with the brownie’s moist consistency. Add the eggs one at a time, mixing thoroughly after each addition to incorporate air, then blend in the vanilla extract evenly.
- Combine Dry Ingredients:
- In a separate bowl, sift or whisk together the all-purpose flour, unsweetened cocoa powder, salt, and baking powder. Gradually fold this dry mixture into the wet ingredients gently, taking care not to overmix. Overmixing will lead to cakey brownies, so stop once you see no more streaks of flour and the batter looks smooth but thick.
- Incorporate Caramel:
- Pour about half of the brownie batter into the prepared pan, spreading it evenly. Drizzle half of the caramel sauce across the surface, then spoon the remaining batter on top and smooth it out. Finish by swirling the rest of the caramel sauce gently with a butter knife to create a marbled effect that lightly permeates through the batter.
- Bake the Brownies:
- Place the pan in the center of the preheated oven and bake for 28 to 32 minutes. Check doneness by inserting a toothpick near the center — it should come out with a few moist crumbs but not wet batter. Remove from oven and let cool completely on a wire rack so the brownies firm up and are easier to cut.
- Shape the Ghost Topping:
- Once cool, cut brownies carefully into squares. Place one large marshmallow on top of each brownie. If the brownies have cooled completely, secure the marshmallow with a small dab of caramel to help it stick. Using a kitchen torch or briefly broiling, toast the marshmallows just until they puff up and turn lightly golden, watching closely to prevent burning—this adds a gooey, spooky texture though it’s optional.
- Add the Ghost Faces:
- Press two mini chocolate chips into each toasted marshmallow to form ghost eyes and bring them to life. Lightly dust the tops with powdered sugar for an ethereal, ghostly glow. Drizzle additional caramel sauce over each brownie for a final eye-catching touch that ties all the flavors together.

My favorite part is the melting together of the caramel and cocoa in the brownie base—a luscious harmony that always reminds me of sharing warm desserts on crisp October nights with friends and family. Topping the marshmallows with chocolate chip eyes is a simple act that turns baking into storytelling.
Storage Tips
Store these brownies in an airtight container at room temperature for up to two days to keep marshmallows soft. If refrigerating beyond that, know the marshmallows will firm up but the brownies themselves stay moist for up to five days. For longer storage, freeze the brownies without the marshmallow topping, then add the ghosts after thawing for the best texture and presentation.
Ingredient Substitutions
For gluten-free needs, swap the all-purpose flour with a 1 to 1 gluten-free baking blend which maintains the chewy fudgy texture beautifully. Use thick dulce de leche instead of caramel sauce for a creamier, milkier caramel flavor variation. Instead of mini chocolate chips, black sesame seeds add a fun nutty crunch while keeping the spooky monochromatic eye look intact.
Serving Suggestions
Add a contrasting swirl of raspberry puree before baking to create a dramatic blood-curdling effect ideal for Halloween parties. Serve with a hot mug of rich cocoa or a scoop of salted caramel ice cream to elevate the gooey indulgence and balance the sweetness. Display on dark parchment or a black serving board to make the ghostly marshmallows really pop visually.

These ghostly caramel marshmallow brownies are an easy crowd-pleaser that combine fudgy chocolate, sticky caramel, and playful marshmallow ghosts. They make a showstopping treat for Halloween or any celebration where fun presentation matters.
