Grandma's Oatmeal Chocolate Raisin Toffee Cookies always remind me of my grandmother. All oatmeal cookies do. I also can't make them without both chocolate chips and raisins. She always did. So to me that's what you do. It just tastes right to me! This version includes Heath or Skor toffee bits too and they are so delicious. I have even thrown nuts in as well. No matter what you add, or plain, these cookies always put a smile on everyone's face!
