Kurtos Kalacs or chimney cakes

This romanian pastry that is called Kurtos Kalacs, is often called in english chimney cakes. It's a fluffy yeast dough (similar to brioche) that is sweetened rolling them to a sugar and cinnamon mix, sometimes even in ground walnuts, and at old times used to be served in weddings. Nowdays, we can find them in small street kiosks that bake them in coal grills.
Hubby tried them first in Prague on a trip for his work and came back telling that it was so soft and delicious that I would surely love it!
I searched for the recipe on the web and indeed I found how to make them at home but eventually never tried them. It took me a couple of years until I would taste them in Budapest (I liked them so much that there was no day passing without eating at least two!!!) But still coming back home, I did not dare to try making them... until one evening, coming back home from a busy day, hubby had made them for me!!! That was a nice surprise :)
So, here it is our homemade Kurtos based on the following 2 recipes found online (thank you both!):
