Put everything in a food processor and blitz until you get a thick mixture. Add more milk or oats if needed to get the right consistency, then add a spoonful of oil to the mixture.
Lightly grease a pancake pan and heat. When it’s hot, turn down the heat and add dollops of the batter, letting them spread out and make circular cookie shapes - 4 or 5 pancakes should fit in the pan.
When the surface of the pancakes is almost set, flip them over and cook for another minute or so.
Repeat with the remaining batter.
Serve the pancakes warm or at room temperature.
