Wicked Witch Hat Cupcakes
Seal the bag and take it out of the cup; twist the bag to force the frosting to one corner; snip a small hole and pipe the frosting onto the cupcakes.
To make the witch hats, top each frosted cupcake with one dark chocolate Oreo. On a pastry mat, knead the black fondant with your hands. Take 1/4 of the fondant and roll it out flat with a rolling pin; take a small biscuit cutter and cut 12 rounds into the fondant (this creates the bottom of the witch hat). Place the fondant hat bottoms on top of the oreos.
