I love chocolate cake and I love hazelnut cake! So I decided to try the best of both worlds. Many of my friends in school say "oh no, I don't like hazelnut cake, make a chocolate cake"! But when they try this their mind is set - they want both. I experimented and found this. This recipe is extremely simple, just follow the instructions.
Sometimes it is helpful to horizontally cut a little off the top of the bottom cake to form a flat base upon which to spread the filling and place the second cake layer on top.
