Fill a 16 oz glass with ice cubes. Then fill to between the third and the half way point with milk. Then add a shot or two of espresso. Then add about a 1/4 cup of syrup..depends on the flavor you want. Whirl it all in a blender. Pour back into glass and top with whipped cream and some drizzled syrup.

For mocha flavor use chocolate syrup
Raspberry mocha chip, use half chocolate syrup and half raspberry syrup, and a few chocolate chips.
For orange mocha chip...same as raspberry but with orange syrup instead of raspberry. But, they use some sort of powdered dried orange peel for theirs.
Caramel...use caramel syrup.
You are only limited by your imagination...and the syrups you can find. I use Torani for the flavored syrups and Hershey's for the chocolate.
You can make these into grown-up frappuccinos by using liquors instead of syrups.
