I attempted it and alhamdulillah the results were better than I ever expected!! The cake was light and fluffy, really really soft and delicate with a perfect crumb texture. All in less time than it would have taken in an oven!
Here is the recipe: Marble Cake
Here is the step by step description corresponding to the numbered pics.
Picture 1: Place a rack or stand in a big heavy EMPTY pot. Make sure the pot is dry and completely clean otherwise if it has any oil or water it will smoke.
Picture 2: Cover the pot with a tight lid and turn the heat on high for 5 minutes. This is to pre-heat the pot in preparation for the cake.
Picture 3: Open the pot, careful it will be hot in there. Place your cake pan gently on the rack/stand.
Picture 4: Cover the pot once more and let the cake start baking! First keep the heat on high for 5 minutes, then lower it to medium and continue cooking for another 20 minutes. This is for an 8″ cake size, it will take slightly more time if the cake is larger or less time if it is smaller.
Picture 5: Open the pan after the baking period, and check if the cake is done. The top will be solid and a skewer inserted in the center of the cake will come out clean.
Picture 6: Turn the cake over on a rack gently and remove the greaseproof paper. As you can see, the cake is done!
Picture 7: This pic is to show you how soft the cake is. I placed a knife under the cake and lifted it, and as you can see the cake is literally bending just with the lift of a knife-tip, it is THAT soft!
Picture 8: Once the cake was cooled, I flipped it over to show the marbled top.
Picture 9: Look how soft my cake is!! Perfect cake without the use of an oven!
