Add 1 cup of milk, flour, sugar, and salt into a medium mixing bowl. Whisk until almost no lumps remain

Add the remaining 1/2 cup of milk and oil, and keep whisking just until a smooth batter forms

Lightly grease a non-stick skillet with a little bit of oil (I suggest using coconut oil) and pour a 1/4 cup of batter into the pan. Immediately tilt and swirl the pan in a circular motion to evenly spread the batter

Cook over medium heat, until the crêpe looks completely set on the top (no wet batter remains), about 1-2 minutes. Then, use a spatula to lift an edge of the crêpe, grab the edge of the crêpe with your fingertips, and flip the crêpe over. Cook for another minute or two

Transfer to a plate. Repeat until all of the batter has been used up. Note: you need to grease the pan just for the first crêpe. However, feel free to grease more if your crêpes are sticking, or you want to add some extra flavor of coconut oil
