Put the egg, flour, milk, oil and sugar in a food processor or blender and whiz until smooth and creamy.
Heat a large frying pan over a medium heat and put in 4 half-ladlefuls of the batter to make 4 pancakes.
After about 1 minute the tops of the pancakes will start to set and air bubbles will rise to the top and burst. Use a spatula to turn the pancakes over and cook on the other side for 1 minute.
Repeat twice more until you have used all the batter and made 12 small pancakes in all.
Bring the pancakes to the table as a stack, drizzled with maple syrup, and serve 3 pancakes to each person, with scoops of ice cream.
