I’m making mini layered cakes and will have some leftover cake bits. Is there anything I can do with it?

I plan on making mini layered cakes for Valentine’s Day for bring into work. I’m doing a trial run today. I’ve learned just how tilted my oven really is but also realized that I’ll have a good amount leftover cake bits. Maybe I should cut my circles closer together or use a slightly smaller cookie cutter so there’s less unused cake. Is there otherwise anything I can use the leftover cake for?
