Since most casserole pans are stoneware or glass (rather than metal) you might need to bake your bars or cake slightly longer, potentially at a lower temperature.

Dishwasher use is not advised, as discoloration will occur due to the cleaning agents used in automatic dishwasher detergent. If you need part of an egg for when you are adjusting a recipe, crack the egg, beat it, and whatever percentage of that mixture you need.Texas sheet cake looks like a standard chocolate sheet cake with chocolate frosting, but larger (often times, the cake is baked in a 13 x 18 half sheet pan—but we’ll dive into that more closely).

If substituting a baking pan that holds the same amount of batter, be wary of the baking time because the dimensions of the baked good will change. The baking time will likely be pretty close to the time recommended, but I would check a bit earlier, and reset the timer from there.

As a 9x13 pan is something that you’ll use a lot over its lifetime, don’t be afraid to take your time. Does it crown substantially over the rim of the pan — or does its top surface hover somewhere right at or below the rim? However, it’s especially important to measure everything out before starting any of the recipe’s steps. I don’t think I’m overselling it: little delights like the spot where your baking project or casserole meets the side of the pan and goes crunchy and crisp, providing textural contrast to the rest of the dish. If you want to measure your pan to be sure, measure it from the inside—one corner to the opposite corner on the same side of the pan.
