Super Easy Steamed Banana Cake

INGREDIENTS

1	ripe banana, mashed
1	egg (can be substituted with 50ml of milk or water; I once ran out of egg and substituted with water and it worked fine)
1	teaspoon oil
2	teaspoons water
2	teaspoons baking powder
1/4	cup icing sugar
100	g (2/3 cup to close to 1 cup) all-purpose flour
2	tablespoons of semi-sweet chocolate chips or raisins, optional

INSTRUCTIONS

1.	Place all the ingredients in a small mixing bowl.
2.	Mix the ingredients with a fork until well blended.
3.	Bring a pot of water to a boil. Steam the cake on a rack for 15 to 18 minutes until a tester inserted into the center of the cake comes out clean.
4.	Remove from the steamer and let the cake cool for a few minutes. Use a knife to loosen the sides of the cake and pop the cake out of the bowl. Here you are, a warm and fragrant cake ready in less than 25 minutes. You may add some chocolate chips if you prefer.
