This recipe for Steamed Golden Syrup Sponge is incredibly easy to prepare. Its simplicity arises from the fact that it is cooked in a microwave oven, significantly speeding the cooking process. I usually steam sponges or puddings in a pan of simmering water, a method that takes a substantial amount of time. However, with this microwave version, everything is ready to enjoy within 30 minutes, whereas steaming in a pan of water can take between one and a half to two hours. As you can see, this version is considerably faster.
The recipe is straightforward and can be entirely done by hand. While it calls for self-raising flour, plain flour with added baking powder will yield the same result. The sponge is adaptable to various added flavours, and in my case, I use lemon, but vanilla or orange would also work well.
To microwave the pudding, you’ll require a bowl that can be covered. I use a plastic pudding basin with a lid, which works effectively. Alternatively, a glass or plastic bowl with similar dimensions, covered with plastic wrap, will suffice.

Ingredients for Steamed Golden Syrup Sponge
As previously mentioned, the recipe uses self-raising flour, and the same amounts of butter and sugar. It also uses large eggs (equivalent to extra-large eggs in the USA, with a weight almost matching that of the other ingredients). My eggs, once removed from their shells, weighed a combined 120g, while the other ingredients were 125g each. The remaining ingredients provide the flavour, consisting of golden syrup and lemon, along with a pinch of salt. I believe that maple syrup or corn syrup would also work well, albeit with a different flavour profile.
Method
The method is straightforward and can be completed by hand. Begin by rubbing lemon zest into the sugar, releasing the lemon oils. Cream together the butter and sugar, then add the eggs and combine them. Stir in the flour and salt before folding in the lemon juice. Measure the golden syrup into the pudding basin or bowl and spoon the batter over it. I used 120g (6 tbsp) of syrup, but you can adjust this to your own preference, using more or less.
Cover the bowl and microwave it for 6 minutes at 750W. During cooking, my sponge actually overflowed a bit in the microwave, but this wasn’t problematic. After cooking, I left the bowl in the microwave for 3 minutes since it was still very hot. Then, I carefully removed the bowl, taking precautions to protect my hands. I removed the lid and turned the steamed sponge onto a plate for serving.

The taste was delightful, with the lemon and sweetness from the treacle shining through. The sponge was soft and springy as well. I tasted it as it was and later served it with custard, which was even better.
