This recipe was in The Kansas City Star food section about 10 years ago. I manage to make them about once a month. No-bakes are a must hav cookie whenever we take a car trip.
In a pan, mix sugar, cocoa, milk and butter. Heat mixture and cook until it boils. Remove from heat and cool one minute. Add vanilla extract, peanut butter and oatmeal; mix well. Drop mixture by teaspoonfuls onto wax paper. Let cool until set.
