I don't want to clutter these boards, but would you use "baklava yapmayi çok zor mu " to say "Is making baklava is very hard?
no it would be this same sentence:
Is making baklava very hard? = Baklava yapmak çok zor mu?
baklava yapmak = to make baklava = making baklava
baklava yapmayı is the accusative form of baklava yapmak you can only use it when it's an object, but in your examples it's a subject so you cannot use that form.
