How to cook
In a bowl, beat the jam, sugar and hot water using an wire whisk until the sugar melts.
Add the oil and stir. Add the nuts and finally, the flour with the soda.
Mix well and pour the finished mixture into a greased and floured cake pan.
Bake in a preheated 356°F (180 degree) oven for about 50-55 minutes.
Check the sponge cake with a toothpick.
Leave the fully baked sponge cake for 15 minutes in the oven, but turn it off.
Then open the oven and leave it to cool down completely.
I sprinkled it with chocolate sprinkles for an even tastier topping.
Although, it is a cake without eggs and milk, it turned out a wonderful and very tasty sponge cake with chocolate, walnuts and jam.
