This is the cookie recipe you'll pass along to future generations. These sugar cake cookies get their unique flavor from sour milk (also known as buttermilk). Whip up in just 20 minutes, then top with vanilla frosting and your favorite sprinkles.
Heat oven to 350°F. Line cookie sheet with parchment paper or lightly grease.
Beat butter, brown sugar and granulated sugar until well blended in large mixer bowl. Add eggs and vanilla; beat until creamy. Stir together flour, baking soda, baking powder and salt; add alternately with buttermilk to butter mixture, beating well after each addition. Stir in small chocolate chips and nuts. Drop by level 1/4 cupfuls or heaping tablespoonfuls 2 inches apart onto prepared cookie sheet.
To sour milk: Use 1 tablespoon white vinegar plus milk to equal 1 cup.
Bake 12 to 14 minutes or until golden brown. Cool slightly; remove from cookie sheet to wire rack. Cool completely. Frost with favorite vanilla frosting; garnish with colored sugar, if desired.
Smaller cookies can be baked. Adjust baking times accordingly.
