Preveat oven to 180 degrees C (fan-forced) and line 12 cup muffin tin with muffin cases.
Squeeze the excess liquid out of the grated zucchini (you should end up with about 6tbsp of liquid.)
In a large mixing bowl, combine the wet ingredients well.
Add dry ingredients and cacao nibs/chocolate chips to the mixing bowl and gently fold toegether until just incorporated.
Pour mixture into each of the muffin cases and leave on the bench to sit for about 10 minutes (this allows the mixture to thicken as the oat flour absorbs the liquid which will help stop the muffins hold their form.)
Bake muffins for 25-35 minutes or until golden brown on top. Leave to cool in baking tray for about 20 minutes before transferring to a wire cooling rack to finish cooling completely.
