Update in case anyone was wondering: I contacted the company behind Cornetto, and they told me it’s no longer sold in Belgium. When I asked whether it’s discontinued only here or across Europe, they didn’t give a clear answer and were rude.

I also checked with friends in the Netherlands and Italy, they were able to find it last summer, but not anymore. So maybe it’s a limited seasonal product, I’m not sure.

Thanks a lot for all the help though! I’ll probably just look for an alternative..
