Very simple steamed sponge. Made in an electric steamer - YES it worked. I didn't want to put the oven on just to make a little sponge so tried this, I can't believe it worked out so delicious. Also very quick.
I still can't believe this worked. You could use your favourite sponge recipe for this or put other fruit in the bottom as long as it's not too squishy. You can have this cake hot or cold but because it is steamed it's best eaten on the same day. If it lasts that long!
