Melt butter in a pan over medium heat

Add condensed milk and cocoa powder. Stir for 15-20 minutes until the mixture thickens (in our case it took much less time though so keep an eye on it) Check the thickness by dragging a wooden spoon through the middle of the pan. The mixture should be separated for a moment before coming back together.

Once thick, spread the dough onto a small cookie sheet and set aside to cool for about 20 minutes.

Once the candy is cool, use a spoon to scoop small amounts of the cooled dough into your hands to form balls. Lightly butter your hands first to keep them from sticking.

Roll the balls in either sprinkles or coconut and set them in mini cupcake wrappers

Chill for 15 minutes before serving
