Kenwood Food Processor fitted with the knife blade
Method:
Pre-heat the oven to 180°C / 350°F / Gas mark 4 and grease two 18cm shallow cake tins.
Fit the knife blade. Place all the ingredients for the sponge in the bowl and process for 5 seconds. Using a spatula, scrape the mixture into the centre of the bowl and process for a further 5 seconds.
Pour the mixture into the prepared tins and bake for 20-25 minutes or until firm to a light touch and coming away from the edges slightly. If you are unsure whether the cake is cooked insert a thin skewer in the centre and it should come out clean. Turn out onto a wire cooling rack.
When cool spread the jam and cream over one of the cakes, top with the other cake and sprinkle with the sugar.
