Recipe(tried): Brigadeiros - Chocolate Candies

This recipe was given to me years ago by a co-worker. They're good!

Brigadeiros

1 (14 ounce) can sweetened condensed milk (not evaporated milk)
2 tablespoons unsweetened cocoa powder
1 teaspoon vanilla extract
1 tablespoon butter
1 jar chocolate sprinkles

Place sweetened condensed milk in a 2-quart saucepan. Sift cocoa powder over and mix in. Add butter and vanilla. Cook and stir over medium heat with wooden spoon until mixture pulls away from sides of pan, about 5 minutes.

Turn mixture out onto buttered plate to cool.

With buttered hands shape mixture into small balls about 2 teaspoons each; roll in chocolate sprinkles. Keep chilled.
