Prinsessakakku in Helsinki?

Hei!

Silly question, but I have been craving Prinsessakakku like crazy since I had an amazing one on a recent trip to Stockholm.

I've tried it at a few different places (including the market frozen one) and none have been particularly great. Not bad - just not quite right to fill the craving.

Any recommendations on where to find a really good Princess Cake in Helsinki, especially the one with vanilla creme?

Kiitos!!
