The way I learned it is 먹을 거야/ 거예요. Is that also correct?

[WFWuUrYo]

Yes both are correct. The differences are formality

I think "we will have cake" should be accepted. It's common to say have in lieu of eat in English

"going to" is used more commonly in English.

[JgtdQ]

Not exactly the same meaning. going to infers a future plan that is not completely decided. Whereas will infers a plan that is set in place and fully decided. However, we do often use both interchangeably.

[LYOYDr]

Just to put it in the cake mix- We shall eat cake.

[MusicianDochi]
