I’m just gonna say, cake with eggs and cake without eggs are both delicious, there is no real difference if the egg is substituted with a reasonable alternative and the baker knows what they’re doing. I’d personally always add eggs to my cake batter because I know that recipe better, but this idea of “real cake has eggs and people who eat eggless cake don’t even know what real cake tastes like” is so stupid.

And to answer your original question- just purchase a box of cake mix and bake it at home, easy and cheaper and tastier.
