Do you craft every item seperately at the crafting station when you have Chococat's companion bonus active?

My sister and I have been arguing over wether you get more bonus items with Chococat's and Hello Kitty's companion abilities when you craft/bake something individually vs multiple at once. I don't feel like you get less/more if you do one or the other. But she insits on crafting everything individually. Whats yalls opinion on this? How do you do it?
