Brigadeiro (bree-gah-day-ro) are Brazil's favorite and most traditional sweet. Deliciously made with condensed milk, cocoa, and butter, they have unique and velvet consistency—the best treat to make your day sweeter and perfect for every kind of celebration. —My Sweet Brigadeiro
Add all the ingredients, including the butter, to a medium saucepan.
Slowly cook, stirring constantly, over low heat until smooth and rich in consistency: It should take about 30 to 40 minutes over low heat, stirring the entire time (yes, it requires lots of patience and love).
Transfer to a bowl and wait until the mixture cools down. (You can cover the bowl with a plastic cling and put in the fridge to accelerate the process.)
Then spread a little butter in the palm of your hands and mold the Brigadeiro dough into little ball shapes (use a teaspoon to help you portion). We like to make bite-sized Brigadeiro, about 1 inch in diameter.
Cover with chocolate sprinkles, chocolate shavings, or your favorite nut, and transfer to a small paper muffin tin. Store, covered, in the refrigerator.
