How to Make Boo-licious Ghost Brownies

Add frosting: Heat the vanilla frosting in the microwave for about 10 seconds to soften it. Stir well, then spoon a generous dollop onto the center of each brownie square, spreading it out a bit.
Decorate the marshmallows: Grab your black writing gel and carefully draw charming ghostly faces on each marshmallow. Let your creativity shine here!
Top the brownies: Place one decorated marshmallow on each brownie, pressing down gently to secure them in the frosting. Enjoy the festive touch these little ghosts add!
Let it set: Allow the frosting to set for about 15 minutes before serving to ensure everything stays in place while enjoying your treats.
