Melt the butter in the microwave or in a heated pan, and allow it to cool slightly before following the steps below.
In a jug mix together the milk, eggs, and melted butter. Whisk together the ingredients together until well combined.
Sift together the cake flour and the salt in a large bowl.
Slowly add the wet ingredients to the dry ingredients whisking as you go to ensure that the pancake batter is lump-free.
Set a large frying pan over medium-high heat, and when hot add a teaspoon of butter. Allow the butter to melt and then pour a small amount of pancake batter into the hot pan, enough batter to create a thin layer on the surface of the pan. Allow the pancake batter to cook until little bubbles have formed. Once the bubbles have formed flip the pancake and allow the second side to cook for about 30 seconds to one minute. Continue with the remaining pancake batter.
Once each pancake is cooked, sprinkle over two teaspoons of cinnamon sugar onto the surface of the pancake. Roll up the pancake and place it on a serving plate. Continue in this way as you cook the rest of the pancake batter.
Once you have finished cooking all of the pancakes add a drizzle of lemon juice over the pancakes. Serve and enjoy!
