In a medium pot melt butter over medium-high heat, once melted add sugar, milk and cocoa powder, mix.
Stirring continuously (to prevent burning on the bottom), bring to a boil and boil for 1 minute.
Reduce heat to low and add peanut butter; continue stirring until peanut butter is melted into the mixture.
Remove from heat, add vanilla and oatmeal. Mix well and use a spoon or small scoop to drop onto wax paper in desired sized mounds. (quantity will vary depending on what size you make your cookies)
Refrigerate for at least 1 hour.
Serve and enjoy!
