These are yummy!
1 can condensed milk
1 tablespoon butter
3 tablespoons cocoa powder
1 tablespoon ground coffee (cafe soluvel)
sprinkles (they're supposed to be brown :P)
Heat all ingredients except for sprinkles in a saucepan.
Stir constantly over low heat for 10 minutes. It should've thickened and pull back from the pan easily.
Transfer to a bowl and let cool.
Rub butter on your hands and make little balls out of the mixture. Roll in sprinkles.
I would suggest doubling the recipe, as these disappear fast! :)
