In a bowl, mix together egg, milk and melted butter until combined.In a large bowl mix the flour, sugar, baking powder and a pinch of salt together until well combined.Incorporate the wet ingredients into the dry ones, and mix well until just combined.Rest the batter for at least 5 mins, in the meantime, preheat a large no-stick skillet or griddle over medium heat (or until it reaches 190C/375F).Grease the pan with a little butter. With the help of an ice cream scooper or small ladle spoon, pour the batter onto the skillet. Gently spread the batter into a small circle and cook until the edges start bubbling.Flip on the other side and continue to cook until golden and cooked through. Repeat until all batter has been used.Once all your pancakes are ready, top them up with your favourite toppings and serve immediately.
