How many does a 10 inch round cake feed?

A 10-inch round cake can typically feed 10-12 people if it's a single layer cake.

Here are some factors to consider:

* Number of layers: A two-layer 10-inch cake would serve more people, likely around 16-20.

* Portion size: If you're serving generous slices, you might need to adjust the number of servings down.

* Type of cake: A dense cake like pound cake might serve fewer people than a lighter cake like angel food cake.

* Other desserts: If you're serving other desserts alongside the cake, you might need less cake.

It's always a good idea to err on the side of caution and have enough cake for everyone. You can always freeze any leftovers!
