Steps
In a small saucepan, combine the cocoa powder, sweetened condensed milk, and unsalted butter.
Cook over low heat, stirring constantly for about 10 minutes until the mixture thickens and pulls away from the sides of the pan.
Remove from heat and let it cool for a few minutes.
Once cool enough to handle, grease your hands with a little butter and roll the mixture into small balls.
Roll each ball in chocolate sprinkles until fully coated.
Place the Brigadeiros in a small paper cup and enjoy!
