It's important to mix the wet and dry ingredients separately to avoid overworking the batter and to quickly achieve a homogeneous texture without liquefying it.
In a mixing bowl, sift the flour, matcha, and baking powder, then mix with a whisk.
In another bowl, beat the egg, sugar, and plain unsweetened yogurt until you get a smooth mixture.
Incorporate the flour mixture and the pinch of salt, and whisk until you get a smooth batter, quite thick but that spreads slowly. If it's too thick, add a little more yogurt.
Heat a non-stick frying pan or crepe maker over medium heat, then butter it with a small knob of butter using a silicone brush or paper towel.
Pour a small ladle of batter into the hot pan, spreading it slightly with the back of the ladle to obtain a nice round shape. Let it cook until bubbles appear on the surface and the batter is slightly dry so you can flip it.
Flip the pancake and cook until golden brown.
Repeat the process with the remaining batter. Place the cooked pancakes on a plate lined with paper towels.
Serve drizzled with maple syrup, honey, or plain, according to your taste. Serve with toppings of your choice.
