Let’s Get Spooky! Your Step-by-Step Guide
Ready for the cutest, easiest Halloween treat ever? Let’s bring these boo-tiful brownies to life!
Part 1: The Fudgy Brownie Base
- Bake the Brownies: Preheat your oven to 350°F (or 325°F for a dark pan). Line an 8×8 or 9×9-inch square pan with foil, letting some hang over the sides for easy removal. Grease the foil. Prepare and bake the brownie mix according to the package directions.
- Cool and Chill: Let the baked brownies cool completely on a wire rack, for about 1.5 hours. For the cleanest cuts, it’s best to then freeze the brownies in the pan for about 15 minutes to firm them up.
- Cut into Squares: Using the foil overhang, lift the brownie slab out of the pan. Peel away the foil and cut the brownies into 16 equal squares (a 4×4 grid).
Part 2: Create the Ghosts
- Melt the Frosting: Place 1 cup of the white frosting in a microwave-safe bowl. Microwave on High for 20 to 30 seconds, stirring every 10 seconds, until the frosting is smooth and has a fluid, pourable consistency.
- Build the Ghosts: Place one large marshmallow on top of each brownie square.
- Drape the Cloak: Carefully spoon about 1 tablespoon of the warm, melted frosting over each marshmallow, encouraging it to drip down the sides to create a ghostly, draped shape.
- Let Them Set: Let the brownies stand at room temperature for about 30 minutes, or until the frosting is firm to the touch.
Part 3: The Finishing Touches
- Draw the Faces: Using the black decorating gel, draw spooky or silly eyes and mouths on each ghost.
- Serve and Spook!: Arrange your finished Boo Brownies on a platter and watch them disappear!
WiseRecipes’ Top Tips for Perfect Boo Brownies
These simple secrets will ensure your spooky treats are a huge, adorable success.
- Line Your Pan with a Foil Sling. This is the number one trick for easy brownie removal and clean cutting! Letting the foil hang over the sides of the pan allows you to simply lift the entire brownie slab out at once.
- Chill Before Cutting. Don’t skip the quick 15-minute freeze! A chilled brownie is much firmer and less crumbly, which is the key to getting 16 clean, perfect squares.
- Melt the Frosting Carefully. The goal is to make the frosting fluid, not hot. Microwave it in short 10-second bursts and stir well in between. If it gets too hot, it will be too thin and will run right off the marshmallows.
- Work in an Assembly Line. For the most efficient decorating, set up your station. Line up all your brownie squares, top them all with marshmallows, and then go down the line spooning on the frosting.
- Embrace the Imperfect Drips! Don’t stress about making the frosting “cloak” on each ghost look perfect. The random drips and drabs are what make them look like real, spooky, flowing ghosts!
Keep It Fresh! Storing Your Spooky Treats
These treats are perfect for making ahead of your Halloween party!
- Room Temperature: Store the finished Spooky Boo Brownies in a single layer in an airtight container at room temperature for up to 3 days. Placing them in the fridge can make the brownies hard.

Notes
FAQs: Your Spooky Brownie Questions, Answered!
Can I make the brownies from scratch instead of a mix?
Absolutely! If you have a favorite 8×8 or 9×9 fudgy brownie recipe, feel free to use that as your base. Just make sure the brownies are completely cooled and chilled before you start decorating.
What if my frosting is too thick or too thin?
If your frosting is too thick to drizzle after heating, you can stir in a tiny bit of milk or water (start with just 1/4 teaspoon!) until it reaches a fluid consistency. If it’s too thin, let it cool and thicken up for a few minutes before you start spooning it over the marshmallows.
Can I use a different color for the ghosts?
Of course! For a fun twist, you could use a vanilla frosting and tint it with a drop of green, purple, or orange food coloring for a whole crew of colorful monsters.
What are some other ideas for the faces?
If you don’t have black decorating gel, you could use a tube of black writing icing. You could also create the faces by melting a handful of chocolate chips and using a toothpick to dab on the eyes and mouths.
