I got this recipe from Vivi my colleague from Brazil. She made it and it tasted Great!

Condensed milk: 1 can (400 gr) Cocoa powder (not suggar added): 200 gr aprox. Butter: 1/2 table spoon the amount of chocolate depends on how the mix looks like and tastes...

Mix all the ingredients Cook everything in a pot, low fire, stir until it comes out of the bottom. Let it cooling down. Make small balls and decorate them with small party candies for cakes. TIP: grated coconut can be added.
