Well I'm in LOVE with Starbuck's Caramel Apple Cider, so while they were making mine one day, I took a peak at what they used. My home version is pretty dang good, and FANTASTIC considering I could make 12 at home for the price of one at Starbucks.
Apple Juice or Apple Cider (not those disgusting little packets of "cider", real stuff 100% Juice like TreeTop)
Caramel (I use ice cream topper)
I heat the juice up on the stove, sometimes I'll throw a cinnamon stick in there, and when it's nice and hot take it off add caramel to your liking and top with Redi-Whip. (btw the whipped cream at Starbucks is about 12 grams of fat per serving, Redi-Whip contains about 1 gram!) I have this a lot, especially if we have people over, I'm totally ADDICTED!
