• Line the cupcake pan and make cupcakes according to the cake box mix instructions. Let cool. With a small pairing knife, carve out a shallow hole in the top of each cupcake, big enough to let a marshmallow to rest in.
• Prepare your frosting: Divide frosting into 3 separate bowls. Using food coloring gel, color one lime green, one orange, and leave the last one white. Thin each frosting out with a few drops of water until it is a little runny, but still slightly thick. Add water a little at a time.
• Stick a toothpick in the marshmallow and swirl it around in the runny frosting to coat. Let the excess drip off, and then stick the toothpick in the styrofoam to let the frosting dry for a few minutes, but don’t allow to dry completely before decorating:

FRIENDLY GHOST:

• Swirl a marshmallow in white frosting. Draw two eyes and an open mouth with a toothpick dipped in black cake decorating gel. Insert into a cupcake.

PUMPKIN JACK-O-LANTERN:

• Swirl a marshmallow in orange frosting. Toast some slivered almonds in a dry pan until lightly browned. Stick one toasted slivered almond at the top as the pumpkin stem.

Draw a nose and mouth with a toothpick dipped in black cake decorating gel. Insert into a cupcake.

FRANKENSTEIN:

• Swirl a marshmallow in lime green frosting. Use scissors to cut a zig zag edged circle out of the purple fruit roll-up(s). Attach to the top of the marshmallow as the hair. Use two mini chocolate chips as the neck bolts. Draw two eyes, a mouth, and a head scar, with a toothpick dipped in black cake decorating gel. Insert into a cupcake.
