Walnut cake with chocolate, without flour / Tort orzechowy z czekoladą, bez mąki

I finally have a moment to post a coverage from preparing a cake for my grandparents - according to the public eye, it was delicious! I discovered the recipe on White Plate, one of my favourite culinary web pages, you can find it here (it is only in Polish, unfortunately, but don't worry, I will translate it soon). I have to admit that there were almost no alterations required, my only note is that 250g butter for the cream is a bit too much, I'd rather put 150-200g. Apart from that little detail, I sticked to the recipe (which happens very rarely, to be honest). You can see the effects of my efforts below.
