Baked Potato Soup

I absolutely love this potato soup and so do my kids which is always a nice bonus!

2 large or 3 medium baking potatoes, baked or microwaved
1/4 c. butter
1/4c. chopped onion
1/4c. all purpose flour
1 can (14.5oz) chicken broth
1 can (12fl.oz.) evaporated milk
Cooked and crumbled bacon, shredded cheese, sliced green onions (optional)

Melt butter in large saucepan over medium heat. Add onion; cook, stirring occasionally, for 1-2 minutes or until tender. Stir in flour. Gradually stir in broth and evaporated milk. Scoop potato pulp from 1 potato; mash. Add pulp to broth mixture. Cooke over medium heat, stirring occasionally, until mixture comes just to a boil. Dice remaining potato skin and potato(es); add to soup. Heat through. Season with salt and pepper. Top with bacon, cheese and onion.
