What can i use instead of molasses?
Both http://www.germanyexpat.org/p/finding-food-items.html and https://www.toytowngermany.com/forum/topic/29436-where-to-buy-treaclemolassescornstarch/ recommend "Zuckerrübensirup," possibly brand "Grafschafter Goldsaft."

I have no experience with using this or how it compares to molasses.
