In a bowl, mix dark brown sugar with hot water until fully dissolved. Leave the bowl to cool till warm.
Then, mix in the two eggs until combined.
Next, whisk in the evaporated milk, oil and vanilla essence until smooth.
Sift in the plain flour, custard powder, baking powder and baking soda. Whisk gently until the batter is smooth with no large lumps, do not overmix.
Let the batter rest for 25 – 30 minutes. Near the end, prepare a 6 inch round baking tray with parchment paper at the base and prepare steamer at medium high heat.
Pour batter through a sift into the baking tray, and steam for 28 – 32 mins until nicely bouncy or a toothpick inserted comes out almost clean. Once the cake is done, remove the lid but leave the cake in there for 5 mins.
Cool the until warm before unmoulding and slicing.
Serve and enjoy!
