Preheat mini-donut maker (you can also cook in a donut pan at 350-degrees).
With a hand mixer, combine the baking mix and milk. This should be liquidy like pancake batter--not thick like biscuit dough. If it’s too thick, add a little more milk. If too thin, add a little baking mix.
Add the cocoa powder and mix with the hand mixer until the color is consistently brown throughout.
Spoon into your mini-donut maker or donut pan. If baking, place in the oven for 8 minutes or until browned.
Remove from the donut maker when slightly browned and the donut maker opens without tearing the donuts. Set aside to cool to the touch.
Heat the chocolate morsels in the microwave for 1 minute, then stir until smooth.
Dip donuts into the chocolate and immediately sprinkle on the non-pareils, as desired.
Serve!
