Step 1: Bring potatoes and cold salted water to cover to a boil in a large Dutch oven. Boil 20 to 25 minutes or until tender; drain. Let stand until cool enough to handle and peel.
Step 2: Preheat oven to 400 degrees F. Press peeled potatoes through a potato ricer or food mill into a large bowl. Lightly fold cheese, 1/3 cup butter, and next 3 ingredients into potatoes. Stir in 1 3/4 to 2 1/4 cups buttermilk, stirring just until smooth and fluffy (do not over- mix).
Step 3: Spoon into a lightly greased 3-quart baking dish.
Step 4: Dot top of potatoes with remaining 2-3 tablespoons soft butter.
Step 5: Cover with foil. Bake in preheated oven at 400 degrees for 30 minutes. Uncover and bake 10 more minutes or until thoroughly heated.
Step 6: Sprinkle with additional chives before serving.
