Line cookie sheets with aluminum foil or waxed paper. Lightly spoon flour into a measuring cup; level off. In a medium saucepan, combine flour, sugar, butter and milk. Bring to a full boil over medium-low heat. Boil vigorously for 3 minutes, stirring constantly. Remove from heat and stir in peanut butter; blend well. Add all the remaining ingredients, stirring to blend well. Cool slightly, then drop by spoonfuls onto lined cookie sheets. Cool completely.
