Put the banana, egg, almond milk and oats into a food processor and blend until you have a lightly textured batter.
Stir in the ground almonds, vanilla extract, cocoa powder and baking powder. Add a little more almond milk if the batter is too thick. It should be thick but still pourable.
Heat a non-stick pancake pan over a medium heat and lightly grease it with a little oil, using kitchen paper to spread it evenly.
Spoon small amounts of batter into the pan and gently spread them into rounds. You can also use small silicone moulds if you prefer.
Cook for 2–3 minutes, until the surface is set and bubbles begin to appear.
Carefully flip and cook for another 1–2 minutes, until cooked through.
Repeat with the remaining batter, adding a little more oil to the pan if needed.
Serve warm with your favourite toppings, such as fresh fruit, date syrup or chocolate sauce.
