I knew something was wrong last time I had a starbucks frappe. I am usually well-behaved and avoid starbucks at all cost, but I was at a Buns & Noodle in the suburbs (I know, double evil) and there were no other, local economy-participating options. So I bought a frappe. I thought it would be like an iced coffee put in a blender and was surprised to get an excessively sweet fatty milkshake. (I like the way coffee tastes, so I don't use sugar. My dairy farmer blood requires milk though - half and half when I feel decadent). So my palate wasn't prepared for the frappe.
A Brooklyn Life takes it a step further. Crafty was equally suspicious of the excessive sweet, but instead of taking it as a sign to stay away from starbucks, she went all math on them. This mediocre beverage is the same amount of calories as a big mac! See the long division yourself.
