Preperation:
Seive maida and baking powder so that it mixes evenly. Add in butter and mix thoroughly in a vessel. In another vessel, mash in banana and mix it with powdered sugar ( run sugar in mixer to powder it). In a 3rd vessel, break an egg into it and beat it till foam starts to form and then add 1/4th cup of milk and mix it well. When done, mix all the above 3 mixtures to form a smooth bacter. if it isn't smooth enough add the rest of the milk(1/4th cup). Add the essence and colour.Then mix this bacter for say 1/2 an hour continuosly, this is because the more you mix, the fluffy the cake will become. When done, Heat your preassure cooker without lid on high flame for 10 minutes. Meanwhile take in your cake mold. Grease it with buter/oil and then dust it with some flour, this is so that the cake doesn't stick to the mold. Then, add the backer to the cake mold. Place a base in the preassure cooker vessel so that the mold doesn't come in direct contact with the vessel bottom; and place the mold over the base in the vessel. Reduce the flame to minimum. remove the preassure cokker gasket and whistle and place the lid. Let it be for 45 minutes. Then let it cool. Take out the cake decorate it and serve!
