Microwave frosting in a microwave-safe bowl at HIGH 30 seconds to 1 minute or until melted; stir until smooth. Let stand 2 minutes.
Place 1 cup melted frosting in a gallon-size zip-top plastic bag. (Do not seal.) Snip 1 corner of bag to make a small hole. Pipe frosting onto each cake square in the shape of a ghost, adding remaining frosting to bag as needed. Pipe 2 dots on each cake using black gel to form eyes.
For testing purposes only, we used Little Debbie Devil Squares and Betty Crocker Decorating Gel.
Yes, its prefab but it is still clever. I make many Halloween appys and desserts for our party,having several easy ones is a huge time saver and still very cute!
This is absolutely on my to do list for this Halloween:)
