Boo-licious Ghost Brownies Ingredients
• Get ready to create something spooktacular!
For the Brownies
- Boxed Brownie Mix – This forms the delicious base; a homemade recipe can be used if you want to make it from scratch.
- Butter (⅓ cup, melted) – Richer than oil, this adds a delectable flavor to your brownies.
For the Ghost Decoration
- Large Marshmallows (9) – These fluffy treats become adorable ghost faces; mini marshmallows can also be used for a fun twist.
- Vanilla Frosting (4 ounces) – Sweet and creamy, it acts as both a topping and glue for the marshmallows; chocolate frosting can provide a different flavor profile.
- Black Writing Gel (1 tube) – Perfect for drawing ghost faces; if unavailable, melted chocolate or edible ink markers can serve as alternatives.
Step‑by‑Step Instructions for Boo-licious Ghost Brownies
Step 1: Prepare the Brownie Base
Preheat your oven to 350°F (175°C), and grease a 9×9-inch baking pan. In a mixing bowl, prepare the boxed brownie mix by combining it with the melted butter and eggs as per the package instructions. Stir until smooth, ensuring no lumps remain. Pour the mixture into the greased pan, spreading it evenly. Bake your Boo-licious Ghost Brownies for 20-25 minutes, or until a toothpick inserted in the center comes out clean.
Step 2: Cool and Cut the Brownies
Once baked, remove the brownies from the oven and set them on a cooling rack for about 15-20 minutes. Allow them to cool completely before cutting. Carefully slice into 9 equal squares, ensuring each piece still retains its shape, placing them lovingly on the cooling rack to maintain that delightful fudgy texture.
Step 3: Prepare the Frosting
In a microwave-safe bowl, heat the vanilla frosting for about 10 seconds. This slight heating will make it easier to work with. Stir the frosting vigorously until it reaches a smooth consistency, allowing it to become slightly runny yet not boiling. With a small spoon, place a gentle dollop of this velvety frosting in the center of each brownie square, preparing the perfect base for your ghostly decoration.
Step 4: Decorate the Marshmallows
Using the black writing gel, draw cute ghost faces on the large marshmallows. Create two dots for eyes and a small oval for the mouth, ensuring each ghost has its own unique expression. Aim for clarity in your designs, as this will add personality to your Boo-licious Ghost Brownies and bring smiles to everyone who sees them.
Step 5: Assemble the Ghost Brownies
Gently press one decorated marshmallow ghost onto the frosting of each brownie. Make sure to secure it in place, allowing the frosting to act as glue. The whimsical marshmallows will now sit atop your brownies, creating a playful yet delicious Halloween treat that both kids and adults will adore.
Step 6: Let It Set
Allow the assembled Boo-licious Ghost Brownies to sit at room temperature for about 15-20 minutes to let the frosting set slightly. This waiting period helps to keep the marshmallow ghosts in place and creates a beautiful, cohesive presentation. Once set, they are ready to be served at your Halloween gathering or enjoyed as a fun treat any day!

How should I store the Boo-licious Ghost Brownies?

What if my frosting is too thick?
No problem! If your frosting is too thick to spread, you can warm it slightly in the microwave for about 10 seconds. Stir it well to achieve a smoother consistency. If it’s still too thick, add a teaspoon of milk, a little at a time, until it reaches the desired texture.
Are there any allergy considerations?
Definitely! Be mindful of any food allergies. The marshmallows typically contain gelatin, which is not suitable for vegetarians.
