Real Franzbrötchen with puff pastry. I am so excited to introduce this recipe to you today. Think of Franzbrötchen as the answer from Hamburg to the cinnamon-roll craze. I was fortunate enough to live in Hamburg for a couple of years and I can tell you, you will always have the scent of cinnamon present wherever you go. Regardless of whether a kiosk or a bakery, one thing you can definitely be sure of if you are in Hamburg is the fact that Franzbrötchen will be sold everywhere. I already introduced these cinnamon rolls here using a simple yeast dough. The lazy version.
