From some time this year they have La Tortita's sweets at university cafe at Campus Augustusplatz (cafe next to Mensa am Park). This semester I've seen (Spiced) Brownies and oat cookies. Brownies are unique & super tasty (nice winter spices) and rich that I could share it with couple friends. My friend liked the cookie as well. When you're in city center and looking for vegan sweets out of Veganz, visit the uni cafe. *seems like they have it at university cafe in Beethovenstraße (6 or 15) as well!
Cons: Only two options..
