How to Adjust Cake Recipes for Different Size Pans?

When it comes to baking a cake, the size of the baking pan matters because of the factors like time required for baking and temperatures.

There's always a pan you can swap out for another size if you have cake batter ready to go into the oven but you realized you have the wrong size cake pan.

The logic behind these changes is such that because the pan is 1 inch larger, more surface area will be exposed. The liquid in the cake batter will evaporate more quickly, which means it will bake faster. To compensate, simply increase the temperature and reduce the baking time.

Why do we Calculate the Correct Quantities of Ingredients?

Ingredients are always part of a recipe. To measure one, it must be put into a container that holds the amount needed for the recipe. As a result, an ingredient takes up space and has volume. In recipes, liquids (cups, litres) or weights (grams, tablespoons) are measured.

The weight measurements correspond roughly to the dry measurements we use: teaspoons, tablespoons, cups of dry ingredients. Measuring up cup can give more accuracy; then again different ingredients which we measure by the same cup have different weights.

So, it becomes essential to measure & note down the exact measurement of a given ingredient for a successful & tasty recipe.

How to perform Cake Pan Conversion Manually?

  • Check the original recipe & baking pan size mentioned there.
  • Compare the pan size in the recipe with what is available to you. If it is the same, then you can directly follow the recipe as it is. If not, then follow the next steps.
  • You need to calculate the conversion factor for the recipe by dividing your pan size area by the given pan size area.
  • In the following step, you will multiply the weight of each ingredient in the recipe by the Conversion Factor which was calculated in step 3.
  • Finally, you are done with the recipe for desired pan size.

Solved Example of Cake & Baking Pan Size Conversions

Given Recipe is for a 2⨰2 rectangular pancake. Find the recipe for a 4⨰4 rectangular pancake.

2 cups (240g) unbleached all-purpose flour

3/4 teaspoon salt

1/2 teaspoon baking soda

3/4 cup + 2 tablespoons (198g) water

3/4 cup (149g) granulated sugar

1/2 cup (99g) vegetable oil

4 1/2 teaspoons (21g) cider

1 tablespoon (14g) vanilla extract

Solution:

Given recipe is for 2⨰2 rectangular pan

As our pan size is different, we have to calculate Conversion Factor

Area of given recipe’s pan

=2⨰2=4 sq units

Area of our pan

= 4⨰4 = 16 sq units

Conversion Factor = Area of our pan/Area of given pan

Conversion Factor = 16/4 = 4

To get the cake of the desired size, multiply the ingredients by 4

8 cups (960g) unbleached all-purpose flour

3 teaspoon salt

2 teaspoon baking soda

3 cup + 8 tablespoons (792g) water

3 cup (596g) granulated sugar

2 cup (396g) vegetable oil

18 teaspoons (84g) cider

4 tablespoon (56g) vanilla extract

So, this will be the new recipe for our 4⨰4 pan.

FAQs On Cake Pan Converter

1. How do I convert baking time to different pans?

The baking time to different pans can be converted by increasing the oven temp by 25 degrees F and decreasing the bake time by a quarter.


2. How do you convert the pan size to baking?

For converting the pan size to baking first you need to determine the volume up to which your pan can hold. Mostly, for the square and rectangle pans, you can multiply the length of the sides.


3. Can I use an 18cm cake tin instead of 20cm?

A different sized tin can affect the baking time of the cake and also the depth of the finished cake may differ.


4. At what temperature should I bake my cake?

Usually, most of the cakes are baked at 350 degrees Fahrenheit, while you can reduce the temperature to 325 degrees to get a flat-topped cake.
