Start by peeling and mashing the banana in a large bowl until it reaches a smooth consistency.

Crack the egg into the bowl with the mashed banana and thoroughly mix them together until well combined.

Gradually add 2 tablespoons of self-rising flour to the mixture, stirring gently until fully incorporated.

Next, mix in 4 tablespoons of oats and 1 tablespoon of chia seeds. Stir the batter until all the ingredients are evenly combined.

If using a pan, heat it over medium heat and divide the batter into 3-4 small pancakes, pouring each portion into the pan. Allow them to cook for a few moments. Once the bottom is golden brown, carefully flip the pancakes and cook until both sides are nicely browned.

Alternatively, if you're using an air fryer, pour the batter into a pre-prepared pancake mold and divide it into 3 equal portions. Place the mold in the air fryer and set the temperature to 356 °F (180 °C). Cook for 11 minutes until the pancakes are fluffy and cooked through.
