College Student Throwing a Party! Need help staying under budget! Suggestions welcome!

Hi guys I invited about 60 friends over for a wholesome get together for my birthday(ie no alcohol expenses). I phrased it as a pancake party so I will be making plenty of pancakes(I already bought a 10lb bag of mix a while ago). I have a budget of $100 and I’m wondering what kind of foods are good to buy that are cheap but also go a long way and don’t seem cheap? I marketed this more as a dessert snack party than anything too serious. I’m open to all suggestions! Thank u! I also I know it’s not frugal to throw parties but I truly believe that spending my money on friends is one of the best ways to spend it and this is what I save up for so my budget is a bit flexible
