Best Overall: Ghirardelli Dark Chocolate Premium Brownie Mix
It's not a surprise that the brownie mix with the top marks for chocolate flavor went to a chocolate brand. Simply put, this brownie tasted like real chocolate instead of cocoa powder and resembled a homemade brownie more than any of the others. It also held together beautifully when cut, something that was very noticeable when we had so many people tasting little bites. Plus, the added chocolate chips really pushed it into the favorite category.

My opinion has been that these are the best Brownie mix on the market. I just love them. I like to add a handful of dark chocolate chips for an indulgent treat. Someone would have to be a chocolate hater to dislike these.
