1. Take oil, Sugar, lemon juice, soda, and few dry fruits and mix well in one direction. (Lime juice and soda substitutes the egg and makes cake soft)
2. Now add the flour, cocoa powder (I used chocolate sauce), dry fruits and water. Beat well the mixture till everything gets mixed and
3. Now pour the above mixed dough, in a wide opened bowl and garnish with dry fruits on top too. Before pouring apply some greasy material like butter/ghee/oil to the bowl and sprinkle the flour powder, so that the cake doesn't stick to the bowl.
4. Now take the pressure pan, heat it for a minute and place this bowl without water and cover the pressure cooker with lid. Note don't use the whistle.
5. Put the pressure cooker in high flame for 2mins and reduce the flame to low and cook for 20mins. Switchoff the stove, and let it cool.
6. Remove the cake from container slowly and upside-down it on a plate to get in a perfect shape. And its ready to serve. Freeze it to serve cool, or even can be served hot.
