In a small bowl, dissolve the yeast in warm water. Let it sit for about 5-10 minutes until frothy.
In a large bowl, combine the rice flour, sugar, and salt.
Add the yeast mixture and coconut milk to the dry ingredients. Stir until you have a smooth batter.
Optionally, stir in the vanilla extract for added flavor.
Cover the bowl with a clean cloth and let the batter rise in a warm place for about 1 hour or until it has doubled in size.
Heat a non-stick pan or griddle over medium heat. Lightly grease with vegetable oil.
Pour a small amount of batter onto the pan to form a round pancake, about 1/4 inch (0.5 cm) thick.
Cook until bubbles form on the surface and the edges start to look set, about 2-3 minutes. Flip and cook for another 1-2 minutes on the other side.
Repeat with the remaining batter, greasing the pan as needed.
Enjoy your meal!
