(Offer rescinded, people are being crappy in the replies, I can't keep up with this bc it broke containment, I have to step away from this):
I used to work at Starbucks. I know exactly how they make every drink. If you ever want an at-home dupe, let me know what one and I probably know how to make it. If not, I guarantee I can figure it out easily enough. Screw Starbucks and their union busting and various other issues, save yourself a few bucks.
For instance: Their mocha is literally just hot cocoa mix with a pinch of salt, and a little extra sugar, mixed with water. Use a hot cocoa packet, add just enough milk to make it into a thinned paste/thick syrup, and add coffee (instant coffee absolutely works for this) and hot milk. It'll taste better and you can get hot cocoa packs that'll work at a dollar tree for 2 for a buck.
