Preheat oven to 350 degrees F
Using a towel or cheese cloth, squeeze as much liquid as possible out of the grated zucchini.
Blend together zucchini, sunbutter, milk, maple syrup, coconut oil and vanilla extract. Whisk eggs in a separate bowl, then mix in the blended mixture.
Combine oat flour, cacao powder, and baking powder.
Add dry ingredients to wet and mix until smooth. Finally, mix in chocolate chips (saving a few to sprinkle on top, if desired)
Fill 12 muffin slots with liners (I love the re-usable silicone muffin cups). Fill each one up about ¾ fill with batter.
Bake for 25 minutes.
