In a large mixing bowl, whisk together egg and sugar.
Add milk, vanilla extract (or other flavored extract such as pandan), oil, salt, baking powder, and glutinous rice flour (or mochiko). Whisk until well combined.
Prepare your waffle iron by spraying with oil and begin heating. When the iron is done heating, pour on the batter and cook for 3-5 minutes or until desired “doneness” has been achieved.
When done cooking, remove and serve! Add some toppings such as fruits, jams, or spreads to enhance the experience!
