So life with a gluten allergy can sometimes seem unfair; however, once bisquick started making this product, things got a lot more equal. It tastes like Bisquick. It works like Bisquick. Hey, it is Bisquick. It just happens to be gluten-free. Perfect pancakes! Enough said.

I've subscribed to receive Pamela's GF cookie mix and after the second delivery of OLD mixes I am returning to buying them in the store.  All of the last mixes during the last several months (6 bags per order x 2 = 12) have been OLD -- not expired, but the chocolate is dried up, light brown and crumbles to a powder.  I discovered it's not possible to return a subscribe 'n save order (for some reason) so I have to throw out the chocolate chips and use Ghiradelli instead.  Whenever I have bought Pamela's from Whole Foods the chocolate in the mix has been dark brown, fresh and never has crumbled to powder.  AVOID subscribe and save on this item.  Buy them in a store.

Looks fresh and clean; I have roasted it in the toaster oven and I also use it in food whole or ground up in the coffee grinder.
