Ingredient Info and Substitution Suggestions

BROWNIE – I highly suggest you use our fudge brownie recipe for this. They’re chewy, fudgy, and by far our favorite brownie recipe. You could also use a boxed brownie mix to save on time if you’d like.

GHOSTS – There are a few ways to do this. We will be showing you how to make a homemade pipable marshmallow using gelatin, water, and sugar. So easy! Otherwise, you can add marshmallow fluff to a piping bag or large Ziploc bag with the tip cut off, and pipe them on this way. Or, you can take whole marshmallows and melt them in the microwave with a bit of water (2-3 Tablespoons), checking every 10 seconds, stirring well once melted. Add the melted marshmallows to a piping bag and pipe right away. If you’re comfortable making meringue, you could also make the ghosts out of it. They’d be super cute with a bit of browning on top!

Add the gelatin along with the cold water to a bowl. Set aside.
Mix together the sugar and water in a saucepan over medium-high heat stirring until the sugar dissolves and the water starts to boil. Once boiling, stop stirring. Allow the sugar mixture to boil until the temperature reaches 238F on a candy thermometer.
Combine the gelatin with the sugar using a hand mixer set to medium for 3 minutes. After 3 minutes, up the speed to high and beat until soft peaks form.
Add the marshmallow to a piping bag and pipe straight onto the cooled brownies.
Use a heavy squeeze towards the top of the ghost, then taper off and pull the marshmallow downward to create the “ghost” shape. Pipe on black gel icing for the eyes and mouths. Allow the ghosts to set for 1-2 hours before slicing.

Frequently Asked Questions & Expert Tips

Should I cut the brownies before or after I pipe the marshmallow on?

It’s up to you whether you want to cut the brownies before or after. Cutting them beforehand will make the ghosts presentable for longer as you won’t be slicing right into them, but they will become disfigured one way or another after pulling them apart or slicing through them. Either way, they’re still cute and still delicious!

How else can I make the ghosts?

If you’d prefer to make the ghosts from premade marshmallow fluff, that’s totally okay. Add the marshmallow fluff to a piping bag and carefully pipe them onto the brownies. As mentioned above, you could also make the ghosts out of meringue. Instead of black icing gel, try mini chocolate chips or M&M’s for the eyes.

Can I make these in advance?

Yes, you can make the brownies one day in advance. Store them in an air-tight container kept at room temperature until ready to serve.
