Combine egg, sugar, vanilla extract and salt. Beat well. And then add flour.

Add water and combine well till you get the smooth batter. The batter should be slightly thick, but spreadable consistency(thin batter will make thin pancake and vise-a-versa). Add chocolate chips to the batter and mix.

Pour a spoonful of batter on a hot pan and move the pan round so as to spread the batter. When the chocolate chips heat up, they will melt. That's when you run the spoon around to spread the melted chocolate and make marble pattern on the pancake.

Let the pancake cook till it looks dry on the top and golden brown at the bottom. No need to cook on the other side. But if you wish, you can flip and cook a bit. Take it out in a plate. Roll it, drizzle some golden syrup and serve! Yummmm!
