I had heard that Trader Joe's Truffle Baking Mix was also very good, and after reading this Consumer Reports review, I added this baking mix to my next TJ's run. This baking mix is made with dutch-processed cocoa and has chocolate chips within the mix.
At $2.99 a box, I added it to my basket and went on my merry shopping way.
When my brownie craving kicked in the following day, I cracked 2 eggs into a medium bowl, and I melted the butter on the stovetop. I poured the melted butter over the eggs (make sure the butter is warm- not hot- or you'll cook the eggs!), and dumped the baking mix.
I gave it a few good stirs...
... and poured the mixture into my greased 8x8 Pyrex baking dish. Beware- the mixture is thick so I used my spatula to "pat" it into the bakeware.
Result: Decadent, moist, fudgey, great depth of chocolate flavor. If you love chocolate, then this brownie mix is for you! I can honestly say it is better than the Ghirardelli Brownie Mix at the grocery store. And at $2.99 for a 16-oz box, it's a great value.
