Fat Free Wholemeal Sponge Sandwich

Makes 1 cake

Make and bake this fat-free wholemeal sponge in under 20 minutes. Using just three, simple ingredients and a filling, this sponge sandwich is quick to bake and there will be hardly any washing up afterwards. For this everyday cake we used two 20cm/8” round tins, although you can use two 15cm/6” diameter tins for deeper sponges.  You can also swap marmalade or chocolate spread for the jam used to sandwich the sponges together.
