I cannot take credit for this recipe although I added a few things. The recipe for donuts can be found here and it is from my good friend at Back Porch Paleo.
I simply added sugar free dark chocolate chips to the mix by adding them to a the sandwich bag I used to squeeze the batter into the donut maker.
The icing is melted coconut oil with 1/4 cup of the chips melted. I simply dipped the donuts into the icing and let them rest on the cookie tray. I prefer to make some with icing and without.
