1 tablespoon unsalted butter, plus more for buttering
1 cup chocolate sprinkles, for coating
In a pan, add the condensed milk, chopped chocolate and butter. Cook over medium heat, stirring, for approximately 10 minutes or until it starts to come off from the bottom. Tilt the pan and you will see the magic happening. Pour the mixture over a plate coated with butter and let it cool at room temperature.
Butter your hands and roll individual brigadeiros. Coat them in chocolate sprinkles and serve at room temperature for ultimate creaminess!
