Pour condensed milk into a pan and add chocolate powder.

Mix together on medium heat and add margarine.

Keep stirring so as not to burn the bottom until the mixture has the texture of fudge and unsticks from the sides of the pan.

Take off heat and allow to cool down in plate until you can touch it without burning your skin.

You can eat it with a spoon or make little balls with it and add sprinkles.

If making balls, grease hand with butter so the brigadeiro doesn't stick to skin.

Feel free to add berries to the mixture to create something different. Experiment!
