Should you find yourself in desperate need of something chocolaty, and with only an empty pocketbook or vending machine, here is a simple solution:
1. Empty 1 packet of Nestle or Swiss Miss hot chocolate into a disposable cup.
2. Pour in approximately 1/4 cup milk.
3. Mix like hell. (It won't want to mix at first, but it will eventually acquiesce.)
4. Microwave for about 35-40 seconds.
The result is an extremely molten brownie milkshake thing. It is so good. And if I've done my math right, only about 110 calories. Mmmmmm.
