1 cup butter, — chilled
1 1/2 cups flour

Cut butter and flour together with a pastry cutter or fork. Stir in sour cream. Shape mixture into a 4 1/2″ square, place on waxed paper, and refrigerate 2 hours. Cut dough into 4 pieces: work with one piece at a time. Sprinkle 2 tablespoons sugar on waxed paper surface and coat dough in sugar. Roll dough in 12″x5″ rectangle, flipping often. Do not reroll any scraps. On 12″ edge of rectangle, mark center. From each short end, roll dough to center mark. Complete this process with remaining 3 rolls. Wrap rolls and refrigerate 2 hours. Cut chilled rolls into 3/8″ slices. Dip each slice into sugar on both sides. Bake on foil lined baking sheet at 375 degrees until golden. Turn over, and bake 3 minutes more. Cool on wire rack.
