Step 1

Preheat the oven to 350 degrees. Spray a large mini muffin tin with nonstick baking spray.

Step 2

Mix together the coconut oil and sugar. Add the egg, vanilla, and banana and mix again.

Step 3

Stir together the flour, cocoa powder, baking powder, salt, and cinnamon. Alternately add the dry ingredients with the milk until everything is mixed in.

Step 4

Add the mini chocolate chips and stir gently.

Step 5

Spoon the batter evenly into the muffin tin. Bake for 11-12 minutes.

Step 6

Remove the pan from the oven and let cool for 2 minutes. Use a butter knife to gently loosen and lift the donut holes out of the pan. Place on a wire rack.

Step 7

Immediately roll each donut hole in powdered sugar and place it back on the wire rack. Once the donuts are completely cooled, roll them in powdered sugar again.
