Recipe Tips and Substitutions

If you’re not a fan of boxed brownies, you can make your favorite homemade recipe. Or, you can go the easier route and just buy un-frosted brownies from your favorite bakery!

The frosting will be pretty runny when you take it out of the microwave, so do it carefully.

You can choose how “drippy” you want the brownies to look. I didn’t let the frosting run down the sides of the brownies, but if you’d like have them look a little more spooky, you can spoon more frosting on.

Make sure to use a high quality black writing gel so the ghosts faces don’t run!

Try these ghost decorations on top of chocolate cupcakes or even mini brownie bites!

What can I use instead of black writing gel?


If you can’t find the black writing gel, you can use an edible ink marker or some melted chocolate chips that you squeeze on with a piping bag.
