In a medium bowl, place chocolate, and set aside. In a small saucepan, combine cream, syrup, butter, and vanilla extract. Bring mixture to a boil over medium-high heat. Remove from heat, and pour hot mixture over chocolate. Allow mixture to sit for 2 minutes.
Using a whisk, stir until chocolate is smooth and melted. Use immediately.
