I have to mention No Pudge Fudge, pretty much my favorite non-fruit dessert. You can make a single brownie in a coffee cup. Three tablespoons of brownie mix. Two tablespoons of nonfat yogurt. One minute in the microwave and you get a hot, delicious brownie.
I like plain because I add some jam for fruit flavor, but they also have raspberry and mint flavor.
It saves me on those chocolate days. That is not an exaggeration. It saves my life.
