In a large bowl, combine the flour, 1/3 cup sugar, baking powder, baking soda and salt. Mix slightly.
Next, cut in the butter until mixture resembles coarse crumbs.
Stir in buttermilk and combine until just combined.
Fold in the chips.
Turn onto a lightly floured surface.
Knead gently 8-10 times or until dough is no longer sticky.
Divide the dough in half.
Gently pat each section into circle. I find it is easier to work with your hands.
Now, brush each circle with butter and sprinkle with remaining sugar.
Cut each circle into six wedges.
Separate wedges and place on a baking sheet topped with parchment paper.
Bake at 425° for 10-13 minutes or until lightly browned.
Serve and enjoy!
