In a bowl mash the banana until very creamy. Whisk in yogurt and egg whites.
In a separate bowl, mix dry ingredients until well combined. Add banana mixture and mix well with a spatula until well incorporated.
Transfer to a microwave safe bowl, or dessert cup, cover with a paper towel and cook about 1 minute and 30 seconds - 2 minutes, depending on desired level of "doneness"
While cake is cooking, mix plain yogurt together with whey protein powder to make vanilla custard. It might look like there is too much powder at first, but it will come together eventually. Same goes for the "lumpy" feeling. Just let the custard rest for about a minute and it will become nice and smooth.
Top cake with vanilla "custard", raspberries and coconut.
