I don't like using artificial sweeteners because of the chemicals and because they don't taste good. I am a caregiver for my diabetic dad, and once I discovered this product I was hooked, except that it is hard to find where I live. When I found it at Amazon I put it on auto ship so I don't run out.  The price has gone up a lot since I first found it on Amazon, however, it still costs more in stores if and when I can find it there. I make limeade with this which I keep on hand at all times. In a gallon container of water I add 1 cup of lime juice and 2tbsp. of stevia powder. It is refreshing and almost no calories and no chemical aftertaste.  My dad uses the stevia in his coffee and his oatmeal. I haven't tried cooking with it although I know they make one designed for baking, which I'll possibly try this winter.

Whats there to say about a fantastic chocolate chip cookie! The only thing that could be improved is if they offered a bushel box of these so you would not run out so fast. Hope these don't go the way of the dinosaur!

We had these along with Omaha prime rib. Both were great. Two where plenty to fill up. Made them in toaster oven in less then 20 minutes.
