On the stove top, mix the butter, milk, and sugar together. Stir occasionally until the mixture is melted together and starts to boil. Boil for one minute and remove from heat.

In a separate bowl, mix together the cocoa powder and the oats until the oats are coated. Add in the sugar mixture from the stove.

Stir well until all ingredients are combined. Let the mixture sit on the counter for about 30 minutes so the oats can soak everything up.

Layer out a piece of wax paper and scoop tablespoons full of the mixture onto it.

Let the cookies *dry* for a few hours on the wax paper before you store them in the fridge.
