No Bake Cookies

I frequent a chatboard and someone posted this recipe so I decided to try it for the holidays. I know I've had these before, but can't remember where. They are super easy (no baking!) and very good!

No Bake Cookies
1 stick butter
2 cups sugar
1/2 cup milk (I used skim)
3 tbsp cocoa powder
1/2 cup peanut butter (I used creamy)
1 tbsp vanilla
3 cups quick oats

Put first 4 ingredients in a saucepan and bring to a boil. Boil about 1min then remove from heat. Add vanilla and peanut butter and stir until smooth. Gradually add oats and stir until combined. Drop by tablespoon full onto waxed paper (I didn't have any so I used foil) and let cool one hour. Enjoy!
