Place the oats in a high speed blender and blend until the oats become powder-like. Add the baking powder, cinnamon and salt to the blender and pulse once to combine. Transfer to a small bowl and set aside.
In the same blender, add the almond milk, egg, banana and vanilla extract, and blend until well combined.
Add the dry ingredients and mix until just combined, being careful not to over mix; a few lumps are okay. Carefully stir in the chocolate chips, making sure to avoid the blender blade.
Heat a large nonstick pan over medium heat. Spray with nonstick cooking spray.
Using a ⅓-cup measuring cup, pour 3-4 circles of batter into the pan. Cook until the pancakes are puffed on top and golden brown on the bottom, 2-3 minutes, then flip and cook on the other side until risen and cooked through, 1-2 minutes more.
Serve with maple syrup, and fresh fruit, as desired.
