how do you calculate baking time when changing pan size

How do you adjust the baking time if you use a different size pan or change the batch size? How long do you cook brownies if you use a 9×9 pan instead of an 8×8? And so on.

Many times, we don’t have the exact size pan called for in a recipe. While meat, casseroles and vegetables generally aren’t all that picky about the pan size, the situation is different with cakes, breads, desserts and other “baked goods.” Here’s how to successfully use a different size pan — and the key isn’t what a lot of other online sources say it is!

If, for example, your recipe calls for an 8-inch cake pan and you only have a 9-inch, relax, no problem. Just increase the oven temp by 25 degrees F and decrease the bake time by a quarter. In this particular example, since your pan is 1 inch larger, more surface area will be exposed.

How to adjust the baking time and temperature for different size pans

For baking, the best pan substitutions are those where the batter is the same depth as was originally called for. In that case, you won’t have to change either the temperature or the time in the oven. The area of the bottom of the pan is the key to figuring this out.

  • If you increase the area, the same amount of batter will be shallower. When the batter is shallower, the center will dry out faster than originally. Compensate by decreasing the baking time and raising the temperature so that the outside will still brown in the shorter time.
  • If you decrease the area of the bottom of the pan, the batter will be deeper and the center will be underdone at the original time and temperature. To compensate, lower the temperature and increase the baking time.

How to know if you need to adjust the baking time

To know if you need to adjust the baking time and temperature, first figure out the area of the pan called for in the recipe. Then calculate the area of the pan you have. (The areas of common pan sizes are at the end of this article, as are the formulas for calculating the area of other pans). If the two numbers are within 10% of each other, you shouldn’t need to make any adjustment. Otherwise, adjust the time and temperature as described above — the exact amount of the changes will depend on how much the depth of the batter has changed.

For example, if a recipe calls for baking in an 8×8 pan (64 square inch bottom) but you have a 9×5 loaf pan (45 square inches), the batter is going to be almost 1-1/2 times as deep. (To figure this, divide the original pan size in square inches by the new pan size = 64/45 = 1.4).

Since it will be deeper, you need to adjust the baking time and the temperature. Lower the temperature 25 degrees and begin testing for doneness according to the recipe directions at the original baking time plus ten percent (it probably will take about 25% more time, but I’d rather start checking too soon than too late).

Remember, the important thing is how deep the batter will be in the new pan compared to the old pan, not how deep the actual pans are in comparison to each other or what the total pan volume is. I have seen a number of pan size conversion charts online that talk about using a pan with the same total volume (it appears that they were all copied one from another since every word is identical) but the reality is that what’s important is the batter depth, not the total volume.

If the depth of batter stays the same but the total amount in the pan changes dramatically — say, going from a 9×13 pan to making cupcakes — use the same temperature but start checking for doneness at half the original time (if going from bigger pan to smaller); if going from the smaller size to larger, it’s likely to take twice as much time, but you might want to start checking at the original time.

How To Adjust Baking Time For Different Size Pans

FAQ

Does size of pan affect baking time?

Changing Pan Sizes If you are using a larger pan or a square pan instead of a round pan, your batter will be thinner and baking time may decrease. If you are choosing to use a smaller pan, the baking time may need to be increased.

How long to bake cake in different size pans?

Cakes in larger pans will generally bake faster (about . 9 minutes per ounce of batter in a 10-inch pan), while cakes in smaller pans will often take longer (up to two minutes per ounce for a 6-inch pan). Meanwhile, cakes baked in a tube or Bundt pan may only need a minute per ounce of batter.

How do you change from 9×13 to 8×8 baking time?

Cut Your Recipe in Half And, because there won’t be a major difference in surface area or batter depth when you pack your halved recipe into the smaller baking dish, you won’t even need to adjust the oven temperature or the cooking time. Just cut all of the ingredients in your recipe in half. It’s almost too perfect!

How much longer to bake in 8×8 vs 9×9?

Generally, going from an 8×8 at 40-45 minutes to a 9×9 will merit time of about 30-35 minutes. You can do some quick math (8×8 vs 9×9 and apply the % difference to the time), but the temperature and food being cooked also contribute — it may not be as straightforward as the math suggests.

How do I adjust baking time for different size pans?

When making adjustments to baking time for different size pans, there are a few key factors to take into consideration. These include the size and material of the pan, the type of batter or dough, and the temperature of your oven. By taking these factors into account, you can ensure that your baked goods come out perfectly every time.

Why do I need to adjust the baking time?

While the temperature of your oven will remain the same, the baking time will need to be adjusted to accommodate for the size of the pan being used. This is because larger pans will take longer to heat up and bake the contents, while smaller pans will heat up and bake more quickly. 3.

What factors affect baking time?

One of the main factors that affects baking time is the size and material of the pan used. Different pans conduct heat differently, which can impact the overall baking time. For example, a larger pan will require a longer baking time, while a smaller pan will require a shorter baking time.

Are baking time conversion charts useful?

Baking time conversion charts can be a helpful tool for making adjustments to baking time for different size pans. However, it’s still important to understand the specific characteristics of the recipe you’re working with in order to make the most accurate adjustments. 8.
