Mix together flour, oats, baking powder, sugar, cinnamon and salt into a large bowl.
In another bowl, combine mashed bananas, oil, vanilla, egg, and milk. Mix well.
Next, use a spoon and mix the dry ingredients into the wet ingredients. Stir until well mixed.
Let pancake mixture sit in the fridge for 15 minutes.
Remove pancake mixture from the fridge and heat a pan on medium heat.
Once the pan is hot, scoop batter into large circles in the center of the pan.
When the edges of the pancake begin to bubble, use a spatula to carefully flip the pancake over.
Cook pancake until lightly golden brown on both sides. Be careful not to burn. If your pancakes begin to burn, your pan is too hot.
Serve pancakes with fresh berries, additional bananas, or maple syrup. Enjoy!
