One Pan Method: Put the butter/margarine in 9"x13" pan and place pan in cold oven. Preheat oven. Remove pan from oven as soon as butter has melted. If butter is hot, allow to cool a few minutes before adding other ingredients. Carefully add peanut butter to pan (remember, the pan is hot), stirring to combine. Add sugar and stir. Continue adding ingredients as directed above, scraping the sides of the pan to combine evenly. Return pan to oven when fully preheated and bake as directed.
