Combine all the dry ingredients (sugar, flour, and matcha powder). Mix well.
Make a well in the middle, add egg one by one. Use a whisk and gradually mix from the middle. You will gradually get the flour from the side.
When it starts getting thick, add a little bit of milk and continue stirring. Keep repeating it until all the milk is added and all the flour has mixed well. The batter should be very runny.
Add the butter, mix well and leave it in the fridge for 1 hour.
Turn the heat of the stove up and heat a non-stick pan. When the pan is hot enough, reduce the heat to medium (and gradually reduce it during the cooking process).
Start from the middle, gradually pour the batter to the center of the pan while tilting the pan in a circular motion to spread the batter evenly.
After a minute or two, until the bottom is not sticky, flip it over and cook the other side for another 30 seconds. Leave it on a wire rack to cool.
