Baked Potato Soup

I forgot to take a picture, but this soup is really good.
4 large baked potatoes
2/3 c. butter
2/3 c. flour
6 c. milk, whole or 2%
3/4 tsp. salt
1/2 tsp. pepper
4 green onions chopped (or if you're like me and forget to buy them, 1 sm. onion chopped)
12 slices bacon, crisped and crumbled
2 c. shredded cheddar cheese
1 c. sour cream

Cut potatoes in half and scoop out pulp and put in small bowl. Melt butter in large pot. Add flour. Gradually stir in milk. Continue to stir until smooth and thickened. Stir in potato pulp, salt, pepper, onions, bacon, and cheese. Cook until heated. Stir in sour cream.
