Only two ways I can think of doing this:
1. Have the Netherlands, in the fight against Spain, become a Kingdom under a surviving William I 'the Silent' who managed to take all of the Spanish Netherlands, and an accidental personal union with Prussia eventually leads to a political union... Now of course that would include the Netherlands, which you might not be looking for, but it would fit your criteria of having the area of 'Belgium' as 'Prussian' - or at least unified with Prussia.
2. Have a personal union between Prussia and Belgium in the 19th Century, though I doubt this would happen as Britain and France would be totally against it.
Germany (Dominated and ruled by Prussia), annexes Belgium after World War I?
doesn't count.
Well the German Empire was basically just Uber-Prussia anyway, it's out of the bext but it's still technically Prussia.
No you can't. At this point in time it was already decided that the Netherlands would gain Belgium. Only the eastern border wasn't decided yet (so Prussian Luxemburg was ok, but not all of Belgium).You could start with this:

Yes. It was decided in (I think) the treaty of London, which was before Vienna. There it was decided that the Netherlands would gain the Southern Netherlands and Willem would become king of the United Netherlands. The eastern borders though were decided at Vienna. Here for example Willem's plan for the Dutch Rhineland was rejected and it was decided that Luxemburg, would become part of the German Confederation (as Prussia wanted Luxemburg too).It was decided before the congress of vienna![]()

It was not the treaty of London. It was this one:But the treaty of London is a only between the brits and the later netherlands. The later Belgium belongs to Austria and is under occupation/administration of Prussia.
So if Prussia didn´t get other areas for their lost polnish lands maybe they get Belgium.
