So, which of the definitions fits this product? In my judgment, neither, really. I made the mix according to the standard directions (not the directions for a more cakelike brownie) and frankly, what I got was pretty much a dense chocolate cake. There was no fudgy-quality to it. It is possible that I cooked it too long -- I have a convection oven and some things I need to cook for less time than the recipe calls for, but if I did overcook it, at least what I got was not dried out.

Now, setting aside whether what I got was a brownie or not, it was very good eating. The flavor was definitely the rich-chocolate flavor of a brownie, it was not dry and I would easily recommend this mix on that basis (I did add a little extra Splenda to the mix as the batter did not taste quite sweet enough to me, which is fairly common with Dixie Diner sweets). The caramel topping was also quite good though I would have appreciated a little more generous amount.

I would like to add that I suspect that it may not be possible to do a low-carb version of the crispy/chewy style of brownie as I suspect that texture is dependent on the chemical properties of sugar and how it interacts with the fat and flour under high-heat. It is possible that no artificial sweetener reacts the same way and there may not be any form of substitution which can create that effect.
