In a mug, combine the coconut oil, pandan extract, natural sweetener and egg. Whisk to combine. Add the coconut and self raising flour and whisk again.
Microwave for 2-3 minutes and until cake has cooked and risen.
Serve immediately, either in the mug or turned out on to a dish, with a dollop of coconut yoghurt, kaya and a sprinkle of shredded coconut.
