• Make the cupcakes and set them aside to cool completely.
• Make the vanilla buttercream frosting by adding storebought frosting to a mixing bowl. Add powdered sugar and whip for up to 2 to 3 minutes.
• Portion the frosting into 5 bowls. You'll only need a small bowl of frosting for the black. Then you'll have one bowl for orange, one for white, one for green, and one for purple. Add the black frosting to a plastic sandwich bag and cut a very small tip at the end with scissors.

Purple Monster Cupcakes

• Use a piping bag with the Wilton #21 star tip. Fill with purple frosting. Pipe a spiral swirl leading to a peak in the center and add a large candy eye on top. Or dot several smaller stars across the top of the cupcake, adding two candy eyes (or more). Feel free to add some Halloween sprinkles.
  

Ghost Cupcakes

• Add white frosting to a piping bag with a large round tip (Wilton #1A). Create a mound of frosting starting in the center and gradually bringing the frosting tip up. Add two white candy eyes for each cupcake to create a ghost face.

Frankenstein Cupcakes

• Use a butter knife to coat a cupcake with green frosting. Dip the knife in water, then tap to remove excess water. Spread it across the frosting to create a smooth, shiny surface. Pipe black frosting in zig-zags to create details such as the hair and mouth. Add two candy eyes. Use peanuts or pretzel sticks to add the electrodes on the side of Frank's head.
  

Jack-O-Lantern Cupcakes

• Smear orange frosting across the top of a cupcake. Wet the knife to and lightly go over the frosting to create a smooth surface. Use a toothpick to lightly press and create roundish lines going down the pumpkin. Use green frosting to create stems at the top of the pumpkin. Use candy eyes or black frosting to create triangle eyes. Continue using the black frosting to create eyes, nose, and mouth for each cupcake.
