I would make these a lot growing up. I was joking with some of my siblings about how I would run upstairs during a commercial brake while watching TV and make these really quick.
In a pot on the stove add (in order):
2 C. white sugar
3 Tbsp. cocoa powder
1/2 C. milk
1/4 C. butter/margarine
Boil for 3 minutes on Medium High heat (That is the key to having them set up well)
1 C. coconut
3-4 C. raw oats
1 tsp. vanilla
Place by 2 Tbsp. scoops on wax paper. Take about 5-10 minutes to set up.
