I think it is something made to poke fun at the omega verse trope. Still, even if it's not supposed to involve cannibalism, it would be pretty hard not to make it about cannibalism since these are personified cakes being "eaten" by the fork population.
The only manga I could find on it was this, and it leaned more toward the cannibalism route: https://www.mangago.zone/read-manga/kindan_no_bishokukai/
I just learned about Cakeverse…. What’s the consensus around this?
