Pre heat oven to 170oC

Sift the flour and baking powder into a bowl then add the rest of the ingredients

Grease two 20cm cake tins and cut grease proof paper in the bottom (I draw round the tins and cut out the circle of paper). Put half of the mixture in each. Use scales to make sure the cakes are even weight

When cool, spread jam on one half and put together in a sandwich. Sprinkle icing sugar on top
