1Take out a medium saucepan put on stove. Heat to medium heat. Add the butter to melt. Next, add the sugar and cocoa, mixing well. Add the milk. Let come to a mild boil and stir occassionally. This needs to boil for about 5 minutes or until mixture reaches soft ball stage. I judge this by stirring the mixture then holding the spoon up high and letting the mixture run off. When the drops start running together and slowly - it is done. Remove from heat. If you cook too much - your cookies will be dry and won't hold together. If you don't cook enough - they will be runny and you will have to eat them with a spoon. Add the oats, peanut butter and vanilla extract. Mix well then drop by spoon fulls onto wax paper to set up. Shouldn't take long. If cooked right - should only take about 2 to 3 minutes to set up.
