Chocolate Oatmeal No Bake Cookies Recipe

I used to make these Chocolate Oatmeal No Bake Cookies when I was a kid. I decided to post the recipe here so I'd always know where to find it. They are so easy and so good. A great recipe to make with young children letting them help drop the cookies.

Ingredients:
1/2 C Butter 
2 C Sugar 
1/2 C Milk 
4 Tbsp Cocoa 
1/2 C Peanut Butter (optional)
3- 3 1/2 C Quick cooking Oats 
2 tsp. Vanilla 

Add the first 4 ingredients in a saucepan. Bring to a rolling boil, and boil for 1 minute. Stir in the next 3 ingredients and drop onto wax/foil paper. Let cool until set.
