Sift the flour, baking powder, caster sugar into a large bowl.
Make a well in the centre and with a wooden spoon, quickly stir in the egg yolk, milk and melted butter.
Whisk the egg white until forms stiff peaks and fold into the mixture.
Then fold in the chocolate chips.
Next, lightly grease and heat a griddle pan (or large frying pan) over a medium heat.
The pan is the right temperature when a drop of water splutters on it.
Use an ice cream scoop (or a jug) to pour equal measures of batter onto the pan (there should be room for 4 pancakes).
Once the pancakes start to form bubbles on top and look slightly dry turn over and cook on the other side until golden.
Once all the pancakes are cooked, makes stacks (3 is a serving) and decorate with banana slices, more chocolate chips and golden syrup. You can also make ahead and reheat on a plate covered in foil over a pan of simmering water or in the microwave.
Makes 12 to 13 pancakes.
