Into a mixing bowl, add and mix the Unsalted Butter (250 gram), Granulated Sugar (1 1/2 cup), and Salt (1 pinch).
Then, whisk in the Egg (2), and Vanilla Extract (2 teaspoon). Add the Self-Rising Flour (2 1/2 cup) and mix everything well until you get a nice and smooth dough.
Make the dough into small round cookies. Roll each cookie dough on the Cinnamon Sugar (to taste), and place it on a baking tray lined with baking paper. Bake under 180 degrees C (350 degrees F) for about 8 minutes.
