Place all the ingredients apart from sparkling water into a medium bowl and using an electric mixer, whisk them all together until you have a smooth batter. Depending on the consistency of your batter, add 1-2 tbsp of sparkling water and mix again. Place your crepe batter in the fridge for at least an hour.
Lightly grease a medium frying pan and heat the pan util hot. Pour about 4 tablespoons of batter into the pan and swirl it around to ensure even coverage. Fry on each side for about couple of minutes, until golden.
Brush with milk, cover with breadcrumbs and fry in vegetable oil on both sides until golden brown.
