I remember these oatmeal cookies that a friend made for me once, with chocolate, and they were no-bake, just chocolate, something else, and the oats, and they were REALLY good, know what I am talking about?
I have a cookie recipe very similar to what you are describing...we call them chocolate balls or reindeer droppings

Here's the recipe:
In a large bowl mix 3 cups oatmeal and 1 cup shredded coconut, mix thoroughly.
In a deep sauce pan put:
1/2 cup butter (melted)
1/2 cup milk
1 tsp vanilla
2 cups white sugar (do not sub)
5 tbsp cocoa
Bring mixture to a full boil over medium heat and stir occasionally. Boil for full 2 minutes. (you want soft ball consistency, if mixture is not boiled long enough the cookies will not set) Pour over oatmeal mixture, mix thoroughly.
Drop by teaspoon onto wax paper and let cookies set (approx 10-20min). Store in covered container. Can be frozen.
Sad hope this is close to what you were looking for!
