In a mixing bowl, combine rice flour, baking powder, sugar, and salt.
In another bowl, whisk the egg, milk, oil (or melted butter), and vanilla extract.
Slowly add the wet ingredients to the dry ingredients and mix until you get a smooth batter.
Heat a non-stick pan over medium heat and lightly grease it with oil.
Pour a small amount of batter onto the pan and cook until bubbles appear on the surface.
Flip the pancake and cook the other side until golden and crispy.
Serve warm with your favourite toppings such as honey, fruits, maple syrup, or yogurt.
