Fantastic! I use all butter and 2 tsp vanilla. I also used 1 cup whole wheat pastry flour and 1/2 cup ap flour. I think I will try nightboats suggestion of chips and raisins, but this is a great recipe!
My husband loves these cookies! I've made them twice. The last time I put in 1 1/2 cups of chocolate chips and a 1/2 cup of raisins. Just delicious!
