How many people will a 12 x 16 cake feed?

It's impossible to say exactly how many people a 12x16 cake will feed without knowing more information! Here's why:

* Cake Thickness: A 12x16 cake can be made in different thicknesses (think layers). A 2-layer cake will serve fewer people than a 3-layer cake.

* Serving Size: How much cake do you plan to give each person? Are you having large slices or small ones?

* Other Food: Is the cake the main dessert, or are you also serving other sweet treats?

* Appetite of Your Guests: How hungry are your guests likely to be?

General Estimates:

* A 12x16 cake is a good size for a large gathering of 50-75 people if you're serving it as a main dessert.

* You can likely feed 100+ people with a 12x16 cake if you're serving smaller slices and have other desserts.

For a better estimate, consider:

* Calculate servings: Divide the total cake volume (length x width x height) by the desired serving size per person.

* Factor in other food: If you're serving other desserts, you can reduce the serving size of the cake accordingly.

Ultimately, the best way to determine the number of people a 12x16 cake will feed is to consider your specific circumstances!
