This recipe can be made with any kind of nut butter. It's not very sweet - peanut butter cookies usually are made with 1 cup pb and 1 cup sugar, so this is only half the amount of sugar. You can add raisins, chocolate chips, craisins, nuts.... whatever floats your boat! For the gluten free flour you can use 1 cup of any gf flour mix. Usually I use rice flour and tapioca starch.
