I make my own mocha shake in the mornings:

ice
nonfat milk
1/3 c. lowfat ricotta for thickening
1 tbsp of unsweetened cocoa
a few splenda packets to taste
1 tbsp of instant coffee

count some of the calories (splenda/cocoa) to your daily sweet treats

You have to really blend it though so the ricotta isn't grainy. I use a magic bullit.

It's REALLY GOOD. Even my teenager likes it, and she doesn't like anything!
