Public-domain recipe with an original dish photograph.
One can of condensed milk. Three or four spoons of chocolate powder or cocoa powder. One spoon of butter (Actual butter and preferably unsalted. No margarine!) Sprinkles (Optional)
Add all ingredients into a pan. Put it under low heat and stir it (preferably with a wooden spoon) until it stops sticking to the bottom of the pan. Remove it from the pan and eat it with a spoon or roll it into small balls. If you chose to roll it into balls, you may also roll them around in sprinkles while still hot.
