In a medium-sized bowl, add almond flour, tapioca flour and baking soda then whisk together. Afterwards, add the milk and egg and mix until pancake batter is formed.
Slice the bananas into ½ inch thick slices. One by one, dip the banana slices in the batter until it is completely covered. Make sure not to over crowd.
On a large pan over medium heat, spray avocado oil spray to then use a fork to place onto the pan. Repeat until you've filled the pan, making sure they are evenly spaced about an inch, and each mini pancake is not touching. Cook for about 1 to 2 minutes or until golden then flip.
Cook for another 1 to 2 minutes until the second side is golden. Enjoy immediately.
