Preheat the oven to 325℉. Lightly spray a muffin pan with cooking spray and set aside.
In a medium bowl, mix together the eggs, maple syrup, coconut oil, apple cider vinegar and vanilla extract.
Slowly mix the dry ingredients into the wet ingredients until just combined. Fold in the chocolate chips.
Divide the batter between the 9 prepared cavities in the muffin pan, and bake in the preheated oven for 20-25 minutes, or until a toothpick inserted comes out clean.
