I am currently volunteering in a senior center and they have asked me to bake desserts for them in a steam table pan measuring

12.75” length x 20.75” width. This measurement computes to 264.56 square inches. How do I figure out the amount of cookie crumbs I will need to get a proper sized crust in this pan? My first attempt will be to make a cheesecake. How best do I convert cheesecake ingredients to accommodate this pan. Is there a formula I can use? Thank you so much for your help.

Yes there is a formula.

But to scale properly your recipe needs to be in weight not volume measurements.

You need to calculate the area of both pans—not just the pan you want to use.

After you calculate the area of both pans, divide the size of the larger pan into the small pan. The number will be the multiplier.

For example:

Say the original recipe calls for a pan 9” x 13”

9 x 13 = 117

The pan you want to use

12.75” x 20.75” = 264

Divide the larger size into the smaller size

264/117 = 2.26,

2.26 is your your multiplier. So multiply each ingredient by 2.26.

For example, say the original recipe calls for the following ingredients:

40 ounces cream cheese (1133 grams)

10.5 ounces sugar (672.7 grams)

6 eggs

US units:

40 x 2.26 = 90.4 ounces cream cheese

10.5 x 2.26 = 23.73 ounces sugar

6 x 2.26 = 13.56 eggs

Metric

1133 x 2.26 = 2560 grams (2.56 kilos) cream cheese

297.67 x 2.26 = 672.7 grams sugar

6 x 2.26 = 13.56 eggs

If either one or both pans are round you need to find the area of a circle.

For example if the original pan was 8” round, then find the area of an 8” circle:

To find the area of 8” round cake pan

1. Square the radius

2. Multiply the radius squared by pi

3. Pi = 3.14

8” radius is 4” - the radius is the distance from the center of the circle to the edge

Radius squared is 4 x 4 = 16

Radius squared x pi is 16 x 3.14 = 50.24

The areas of an 8” round pan = 50.24

Now you perform the same functions as above, divide the larger area into the smaller area.

264/50.24 = 5.27

5.27 is your multiplier.

Multiply each ingredient by 5.27

If the pans are of different depth, you need to calculate for the additional volume. Which is a whole post on it’s own. It that’s the case, let me know and I will outline the steps.
