The cup was a caramel cake with Caramel Vodka flavoring and the center was a browned-butter frosting. I made chocolate designs (using a decorator bag and a No. 2 tip) to represent steam from the coffee. I saw this on a website and had to try it. All you do is wrap parchment paper and foil around a coffee cup and then remove the coffee cup and spray Release inside of the mold before pouring in the batter. I placed the molds in a muffin tin to keep it upright. The instructions said place a container in the center so the middle will be hollow but thick, but I filled it with the batter and then used a 2-inch cookie cutter to hollow out the center.
