I got this recipe from the Betty Crocker’s American Country Cooking cook book. I have cut the sugar down by 1/2 cup.
1 1/2 cups packed brown sugar
1 cup butter
1/2 cup buttermilk (can use regular milk)
1 teaspoon vanilla
4 cups quick-cooking oats
1 3/4 cups flour
1 teaspoon baking soda
3/4 teaspoon salt
Heat oven to 375º. Mix brown sugar, butter, buttermilk, and vanilla in bowl. Stir in remaining ingredients. Shape dough into 1 inch balls. Place about 3 inches apart on ungreased cookie sheet. Flatten cookies with bottom of glass dipped in water. Bake until golden brown, 8 to 10 minutes. Immediately remove from cookie sheet.
I have added macadamia nuts and dried cran strawberries to this recipe. The kids really enjoy them.
