To add natural sweetness and flavor, mash ripe bananas into a smooth puree.
To make batter, mix rice flour, water, banana puree, and a bit of salt.
For added taste and a rich texture, mix with cardamom powder and grated coconut.
For the banana dosa batter to absorb the flavors, let it sit for ten to fifteen minutes.
For non-stick cooking, heat a tawa and lightly coat it with oil or ghee.
Spread the batter uniformly into a thin dosa shape using a ladle after pouring it onto the tawa.
Cook till golden brown, turn, and serve hot with jaggery syrup or coconut chutney.
