I like my pandan sponge cupcakes very much. Made with pandan juice and coconut oil, the little cakes are very fragrant and the green colour is totally natural. The crumb is soft and fluffy, and it's still moist the next day.
If you're new to the whole egg method for making sponge cakes, please refer to my post on vanilla sponge cupcakes for tips on how to mix the batter without deflating it.
