Peanut Butter ranks as one of my all time favorites....I love spoonfuls of crunchy all natural peanut butter right out of the jar! I love soft peanut butter cookies. PB cliff bars, powerbars, balance bars you name it....and now GU comes out with PB GU. Rachel had a pack on Wed and I was uber jealous as she enjoyed it at the top of our biggest climb....I was determined to score a taste. I was able to score a packet and it was every bit as good as I hoped..... This is the best GU has done! I am already thinking of a gel flask and mixing PB and Chocolate!!
