Add 2 tablespoons of sweet cream butter, 14 ounces of sweetened condensed milk and 1/2 teaspoon of vanilla extract into a small saucepan and place over medium low heat
While the mixture is warming, sift 1/4 cup of cocoa powder and a pinch of salt into the saucepan and stir to combine
Cook while stirring constantly until the mixture thickens to the point that when you scrape your spatula across the bottom of the saucepan, the mixture takes a few seconds to recombine
Transfer the mixture into a greased bowl, cover and chill until completely cooled
To shape, pour some sprinkles into a shallow bowl, grease a small spoon or ice cream scooper and grease your hands
Gather equal sized portions of the brigadeiro mixture, roll into round balls and then roll in the sprinkles until the outside is completely coated
Place the shaped brigadeiro into mini cupcake liners or mini paper cups
Store in an airtight container at room temperature for 3-4 days or chill for up to 2 weeks
