Pardon? You mean the traditional Belgian, Dutch, French, and German cookie? Because it's a cross-border (food) cultural good, it's not something invented by, or to this day cherished in, one specific country.
Oh no question, biscoff is yours, I will give you that any day of the week (and then ask if I could have one, of course). Even speculoos is pretty much Belgian. But speculaas... come on author, you clearly did _some_ research, why get this wrong?
The nomenclature is quite loose. Speculaas and speculoos will be used interchangeably in parts of Belgium. "Spéculoos" will refer to both in the french-speaking part, while I anecdotally noticed Flemish people will use "speculaas" even for biscoffs.
That's why I only eat kruidnoten, less of a linguistic quagmire.
