Make sure to have all the ingredients measured and ready to add to the sauce pan. This will ensure that you have the perfect result for these cookies.
In a large sauce pan, combine the sugar, margarine, milk, cocoa powder, and salt.
Bring to a boil, stirring constantly for 1 minute.
Remove from heat, add the peanut butter and vanilla, stir until well blended.
