Bring to rolling boil, butter, sugar, cocoa, and evaporated milk.

Boil for 1 minute, without stirring.

Remove from heat and stir in 1 teaspoon of vanilla, 1/4 cup peanut butter and 3 cups oatmeal or quick oats.

Quickly drop rounded spoonfuls onto waxed paper or aluminum foil.

Cookies harden as they cool.

This is fun to make with your children! :)
