For all the big time HP fans you're dreams are about to come true in a majorly OTT way!
Combine all ingredients for butterbeer, except cream soda, in the bottom of a glass or beer mug and stir well. If the cinnamon doesn't seem to be mixing well try warming it slightly until it's smooth. Fill cups with enough cream soda so that you're leaving about 1 1/2 inches of space below the rim. Stir a little if necessary and add 1 to 2 scoops of caramel coconut ice cream to top. Serve immediately.
