Classic Apple Sponge Cake with Cinnamon

Sometimes I get a huge need to bake, often I don't know what I want to bake - just something - and I end up browsing through my baking books to find out what it will be. A scenario like this took place yesterday and the lucky winner was.... Apple sponge cake!
When I found the recepie in the book I realized that I had forgotten about this kind of fruit cake and when I took the first bite and tasted the sweet/sour apple pieces together with the sponge cake and cinnamon I realized how much I missed it. Apple sponge cake is far too underestimated and I swore to myself that I will bake it again very soon. And then again and agian and again....
Oh and remember, you can replace the apples with whatever you like such as pears, rhubarb, blueberries and raspberries!
