Isaura – Polish cheesecake chocolate cake

I always wonder what should I talk with you about. The weather? The cats? Life philosophy?
The cats are sleeping, the weather is awful and I wish I could follow this philosophy. Well I can, but I just don’t know the answer to the question yet or maybe I’m just a little bit too scare to answer it.
Anyway let’s talk about Polish cakes.
After I shared this cake with my coworkers I heard from one of them “I’ve never eaten something like that, it’s chocolate cake and it’s cheesecake”. Yes, indeed it is a chocolate cake and cheesecake in one, but don’t tell me you never thought about it before.
The origin of the name probably is based on the Brazilian tv series “Isaura the Slave Girl”. It was broadcasted in Poland in 1986 on Sundays. I was only 4, but I remember that everybody watched it. My parents say it was so popular that all streets in cities went empty as literally everybody was watching it.

Isaura was one of my favourite cakes during high school. I used to bake it in something called prodiż (electric baking tin), you probably won’t believe it, but most of the cakes baked there perfectly. It was also great for potato cake, or casseroles. This time I went for other recipe than usually as it had less butter and sugar, but it is as good as I remember.
