Guess what? My mother-in-law took me up on the monster cookie experiment! (see my original Monster Cookie post) See below for her message and the results!
I conducted the cookie experiment this morning. Made the Monster cookies with flour & without. See the progression of pictures. It was fun! Clearly, the cookies without flour were better at our altitude. Those with flour were more crumbly & less tasty. Those without the flour were chewy & the peanut butter flavor was strong. Without flour, they were flatter, but still had a great cookie look.
Your Father-in-law & Uncle appreciate your asking for this experiment!
