For this chocolate orange orange cake I made my favourite moist chocolate cake recipe
I then added orange zest to the batter to give it the chocolate orange flavour.
After that, when the cakes are baking or cooling I made some chocolate buttercream. I added some orange zest to the chocolate buttercream to make it chocolate orange buttercream.
When the chocolate orange cakes cooled down I took one cake and put it on a cake plate, spread some chocolate orange buttercream on it.
I put the second cake on top and added some buttercream on top. You can pipe it on or spread it with a knife. Put some chocolate pieces on top so that there is a piece of chocolate on each slice.
Grating some chocolate on top gives a nice finish but this is optional.
Cut and serve.
