Optional: 1 cup chopped dates and/or 1 cup chopped walnuts
Instructions
Preheat oven to 375°F.
In the bowl of a stand mixer, cream ¾ cup unsalted butter (softened) and 1 cup brown sugar together until light and fluffy. Add 2 eggs, one at a time, beating after each addition. Add 1 teaspoon vanilla and beat to combine.
In a separate bowl, whisk together 2½ cups all-purpose flour, 1 teaspoon baking soda, 1 teaspoon cream of tartar, ½ teaspoon salt, ½ teaspoon cinnamon and ¼ teaspoon nutmeg.
Alternate adding the flour mixture with ¼ cup milk to the butter/sugar mixture, stirring just until combined. Add 1 cup raisins and the dates and/or walnuts, if using.
Drop by 2-tablespoon sized cookie scoop onto a baking sheet.
Bake for 9-11 minutes or until the cookies no longer look wet in the center. Let cool on the baking sheet for 5 minutes, then place on a wire rack to continue cooling.
