In a small food processor, puree the banana with the milk and vanilla. (or mash it really well by hand - you want it pretty liquified).
In a separate medium sized bowl, mix together the dry ingredients. Pour the banana/milk mixture into the dry ingredients and stir until just combined. Stir in the chocolate.
Heat a few teaspoons of coconut oil in a large skillet over medium heat. Using a ¼ cup measuring cup, scoop the pancake batter into the pan. Flip when bubbles form in the batter (about 1 minute). Let the second side cook for about 30-60 seconds and remove from heat. (check the first one to make sure it's done in the middle, if not, you may need to reduce heat to low and let it cook a little bit longer).
Serve pancakes warm with the syrup of your choice.
Enjoy!
