Preheat oven to 350 degrees. 

Combine cake mix according to directions, substituting half of the water called for with coffee of your choosing. Mix well and dump abtter into a gallon size plastic bag. Snip the tip and pipe batter into a donut pan that has been sprayed with cooking spray. 

Bake donuts for 15-20 minutes. Allow to cool in pan 3-5 minutes, and carefully remove to cooling rack. 

While donuts are cooling, warm 4 oz of coconut cream in a small microwaveable bowl. (If you can only find coconut milk, i would suggest using 3 oz of full fat coconut milk instead of 4.) 

Add chocolate chips to warmed coconut cream and allow to set for 5 minutes. (I usually cover the bowl with a small bread plate. Stir until all the chocolate is melted. 

Dunk cooled donuts halfway into ganache and allow excess to drip off. Flip over and place on cooling rack or parchment paper. Sprinkle with sanding sugar if desired.
