Grease a 7 inch cake tray. Dust with flour evenly, shake it and invert it in the kitchen sink to remove excess flour. Or simply line a parchment paper. Set this aside.

Add salt to a pressure cooker or any heavy bottom large pot/ kadai and spread it evenly.

Cover the salt with a plate. Place a ring/trivet or hot pot stand over the plate.

Remove the gasket and weight, if using a cooker. Cover the cooker or pot with a lid and begin to heat it on a medium heat.

Pour milk, sugar, vinegar, melted butter (or oil) and vanilla to a mixing bowl. Stir well until sugar dissolves.

Place a sieve over the bowl. Add flour, baking powder, baking soda and salt to the sieve. Lightly mix them up with a spoon. Sieve it. (check video for help)

Gently mix the wet and dry with a spatula or a whisk, until the flour is just combined well. Do not over mix the batter.

Pour this to the cake pan. Knock it a few times over the counter. Brush milk on top to get a golden top. This is optional.

Hold the cake tray with a tong and place inside the cooker/ pot, on top of the trivet/ring or stand. The cooker has to be hot inside at this stage.

Cover the cooker with the lid. Pls note the gasket & weight have to be removed.

Bake for 50 to 60 mins on a low flame. When the cake is completely baked, a tester inserted comes out clean.

The cake top will be fairly dry when you touch it. If it is still moist, bake for few more mins.

Cool the cake tray for 10 to 15 mins over a wire rack, so it won't sweat at the bottom. Later invert it on to a wire rack.

Cool completely before frosting or slicing.

Preheat the oven to 180 C or 350 F for at least 15 mins.

Bake it for 30 to 35 mins. Tester inserted comes out clean. Adjust the time to suit the size of your pan and oven.

Pour water to a pot and heat it. The water level has to be less than half.

Place another bowl or pan over the pot. The bottom of the bowl or pan must touch the hot water but not the pan inside.

Also make sure water doesn’t seep into the top bowl or pan.

Add 100 grams of chocolate or chips. Keep stirring until the chocolate melts and turns smooth.

Make sure the cake and the chocolate both are cool and not hot.

Pour the chocolate over the cooled cake and spread it evenly. Top with some sprinkles if you have. Slice the cake and enjoy.
