Fannie Merritt Farmer, a culinary pioneer and the head of the Boston Cooking School, is recognized as the creator of the first oatmeal cookie recipe in the United States. Her original recipe in 1896 featured milk and cream, but raisins quickly became a popular addition to this beloved treat. The recipe below brings together the warm flavors of brown sugar, cinnamon, and oats with the delightful chewiness of raisins. This is a classic oatmeal raisin cookie that is recognizable, comforting, and delicious, but the addition of buttermilk adds a surprising tang and keeps the cookie moist. The chopped walnuts provide an extra crunch. This recipe comes from Taste of Home, courtesy of a helpful reader. She says that her mother acquired the recipe in 1910, when she worked as a housekeeper. Her employer’s wife shared the recipe, and it now lives online for all of us to enjoy.
