Who makes the best Brownie Mix?

Ive been using Martha White Brownie Mix with Walnuts. Ive been very happy with it, its a fantastic product, however my local grocery store has removed it from stock.

I like a slightly more cakey and less gooey brownie. Not spongey cakey but not gooey.

Anyways, I look forward to your recommendations.

I actually prefere Pecans, but I usually just place them on top with a slight butter spray and salt spinkling, so that they roast nicely. The walnuts inside give some more nut cruch...lets face it, walnuts are pretty bland (excepting for Black Walnuts).
