Melt the white chocolate wafer. If you don't have a melting pot you can use the microwave. Melt in 30 second increments and be careful not to burn.
Spread out the wax paper.
Use one spoon to drop a quarter-sized dollop of chocolate onto the wax paper.
Use a second spoon to pull the chocolate down so it makes the ghost shape. If you watch the video above you can see how I did it. The Chocolate Ghosts come after the Candy Corn Rice Krispie Treats.
Add the eyes.
Let dry for about 20 minutes.
Carefully peel them away from the wax paper.
Add the mouth with the black cake gel, black frosting or black edible pen marker.
