How many cake mixes needed for a 12x12x2 cake pan?

For a 12x12x2-inch cake pan, you typically need about 1.5 to 2 standard cake mixes, depending on the brand and recipe. A standard cake mix usually yields enough batter for a 9x13-inch pan, which is smaller than your 12x12 pan. To ensure you have enough batter, consider using two mixes or adjusting the recipe accordingly.
