Chocolate-peanut Butter No-bake Cookies

Why I Love This Recipe
I made my ex get this recipe from his mother because he kept harping on the wonderful cookies she made. When he wrote down the ingredients, one of them was "stk but" so I call them Stuck-Butt cookies. Gross, I know, but I just can't help it. The peanut butter in the original recipe was creamy OR crunchy, and you can leave out the coconut or substitute 1 c. chopped nuts if you prefer.
Ingredients You'll Need
2 1/2 c. sugar
1 stick butter, melted (stk but)
4 tbsp. cocoa
1/2 c. milk (you can use evaporated milk if you like)
1 tsp. vanilla
Mix-ins:
1/2 c. crunchy peanut butter
2 1/2 c. 3-minute oatmeal
1 c coconut
Directions
Mix all ingredients over medium heat until boiling. Boil for one minute, stirring contantly.
Then remove from heat and stir in: any of the mix-ins you choose.
Drop by spoonfuls onto wax paper and let cool.
