i just made great peanut butter cookies that are 80% tf, but you could do them 100%. i followed mark bittmans regular pb cookie recipe and subbed my tf ingredients when needed:
cream 2 sticks butter with 3/4 cup sucanat, 3/4-1 cup real pb chrunchy or smooth, add in two eggs, blend, add some vannilla. then mix wet ingredients with 1 teaspoon baking bowder, 2 cups flour of your choice, i used 1 cup sprouted whole wheat flour, 1/2 cup almond meal and 1/2 c white king arthur flour. add a small dash of real salt. add in semi-sweet chocolate chips or walnuts or salted peanuts or coconut shredded. form dough into small balls and flatten with a fork. bake on a greased cookie sheet at 375 for about 9 minutes.
