First of all, the filling I am writing about is already close to double the normal amount… But if I am honest, I have several time taken it even further and used even more. I would not use too much butter though since it easily just melts out and drips through my whole oven :( The best is to use small paperforms if you like to go hardcore on the filling.

Of course it will work excellent with the cinnamon mix you are suggesting. You could also add raisin as we do in sweden but my german friends tend not to be such great fans of raisins so I never do that here.

My mom used all different kinds of filling, marzipan mixes for example. Or hazelnut spread.

One of my fav is cardamon!

So, a lot to try. But I am so glad you liked them!
ALl the best from Berlin!
