Somewhat related, I flew out of Schiphol (Amsterdam airport) about ten days ago. I was bringing these as treats for my colleagues in Cyprus: https://www.ah.nl/producten/product/wi104211/ah-gevuld-speculaas-met-amandelspijs

They stopped my wheeled carry on. Dude looks very serious. Points to the half of the suitcase with the treats in it and signals for me to open it. I do, and he just shakes his head no. "You cannot bring that" he said, to which I replied, "Um, I've been bringing it there for years." He shook his head again, said "no" then broke into a big smile and said "I'm just kidding man, they looked like drugs bricks under the x-ray.

So probably won't be bringing that unfortunately very popular Dutch treat to anyone else again.
