I use both PB2 and Better n' Peanut Butter. I personally, like to bake with Better N' Peanut Butter because of the consistancy. It tooks better in cookies and brownies. Though, the taste isn't as natural as PB2. If you are gonna use PB2 for baking play with the your water amounts. That why you can get the best consistancy for what you are baking!
Sidenote: A tsp of PB2 mixed in FF Vanilla Ice Cream. TO DIE FOR.
And that's for sharing the info about the choc PB2, I cannot wait to try!
