In a medium saucepan combine flour and melted butter. Cook on medium-low heat, stirring constantly for about 30-45 minutes. Now this will take a little bit of patience, when it's finished it should be similar to the color of peanut butter. Be careful not to let it burn! Feel free to add a little more flour or melted butter to reach the consistency of soft cookie dough.
