I'm making cake pops for a Bridal shower in two weeks and I'm trying to plan ahead of time. I have to make 75 cake pops and I'm trying to get an idea of how much cake to make.

Is there a chart that shows pan size to cake pop amount? Or does anyone have an idea?

It would depend on your ingredients and method.and size of pops.Are you rolling cake with frosting ,rolling cake , or baking them in a. cake pop pan ?
A couple weeks ago I made owl and teddy bear shaped cake pops with cake and cheesecake no frosting in the mixture. I "think " I used a 9" pan for cake and cheesecake which made about 3 doz . or more.

Out of one cake mix (whether it be from a pkt or from scratch) and using a Tablespoon of mix for each cake pop I usually get between 20 - 22 cake pops (and always make spares just in case a couple crack and don't survive the dipping process) - Good Luck!

Given that I made 350 of these over the weekend for a wedding (no joke, it took FOREVER), I'll tell you what I did. I had to make 4 flavors: 75 each of three flavors, 100 of the 4th. I made 10x15" sheet cakes in 2 inch deep pans, and that was enough for the 75 servings. I used a 1.5" diameter meatballer. So if you use a larger one, like a 1.75" meatballer, you'll need more.
