These are delectable snack/dessert made using condensed milk and cocoa powder.They are also known as "Negrinho" or Blackie in some parts of Brazil. The condensed milk is cooked in butter along with cocoa powder and the result is rolled in chocolate sprinkles (vermicelli or jimmies as they are also known) to get a dark brown truffle like sweet or laddoos as we can also say. This said the work is definitely tiring and I hope I have made justice to the recipe I adapted from here. Do watch the accompanying video before you attempt a brigadeiro.
Unsalted Butter: 2 tbsp + more for greasing
Condensed Milk: 1 can ( 14 oz)
Cocoa Powder: 2 tbsp
Water: 2-4 tbsp (for mixing the cocoa powder)
Chocolate sprinkles: for rolling (I also used coconut gratings and coloured sprinkles)
On medium-low heat, melt butter in a thick bottomed pan. As soon it is melted,add in condensed milk.Also add in coco powder mixed with water.Cocoa powder takes time to dissolve in condensed milk and may form lumps.So to better avoid the lump,add the coco powder to little water,mix/stir well so that no lumps are there and add this mix to the condensed milk and stir well to get a brown thick liquid.
Keeping the heat on med-low (I used the lowest possible heat),using a wooden spoon start stirring the mix preferably in a circular fashion and from the sides for about 20-40 minutes. We have to cook the condensed milk + cocoa and the water has to evaporate.If we leave the mix alone,then the mix may burn.So keep on stirring and cook as the mix gets thicker and thicker (reduces in volume).
Since coconut laddoos were my childhood favourite I also rolled these in fresh grated coconut and also in coloured sprinkles just to add some colour.traditionally only chocolate sprinkles are used.
