How many boxes of cake mix to use for a 12 inch cake?

Here's why:

* Standard Cake Mixes: Most cake mixes are designed to make a 9x13 inch cake, which is roughly the equivalent of a two-layer 8-inch cake.

* Scaling Up: To make a 12-inch cake, you'll need a larger volume of batter. A 12-inch cake is much larger than a 9x13 inch cake.

* Double the Mix: Doubling the cake mix will give you the appropriate amount of batter for a 12-inch cake.

Important Note: This is a general guideline. Some cake mixes may have different directions. Always check the package instructions for specific recommendations on how much mix to use.
