Sheet Cake Servings Formula

Perhaps you have a pan that is a different size than shown above. To determine how many people your cake will serve, you can use this simple formula below. 

Cake pan’s area (pan’s length X pan’s width) ÷ Cake serving area (cake piece length X cake piece width) = total number of servings

The cake pan’s area is determined by multiplying the pan’s length by the width. If you were using a 9 x 13 cake pan, you would simply multiply 9×13. 

You can then determine the cake serving area, by multiplying the length of the piece of cake by the width of the piece of cake. For example, if you were cutting pieces of cake that are 2-inch squares, you would multiply 2” x 2” to find the cake serving area. 

Then to figure out your total number of servings you take the number you found for the cake pan area and divide it by the cake serving area that you found above. This will give you the total number of servings for your size cake.

Example Calculation

Cake pan’s area (pan’s length X pan’s width) ÷ Cake serving area (cake piece length X cake piece width) = total number of servings

Cake pan’s area (9in X 13in) ÷ Cake serving area (2in X 2in) = total number of servings

Cake pan’s area (117) ÷ Cake serving area (4) = total number of servings

29.25 = total number of servings 

Choosing the Right Sheet Cake Pan for Your Needs

Total servings. Make sure you choose a cake pan that is large enough to serve as many people as you need. Also, be sure to take into account what size pieces you intend to cut the cake into.

The most common size of cake pan is a quarter cake, however, if you are hosting a larger event such as a wedding, you will want to use a much bigger pan. 

Nonstick. Make sure that you use a nonstick cake pan, or use cooking spray, cover the pan in a layer of flour before adding your cake batter, or use a pan liner so that you can remove the cake easily if you are baking your own cake.

How Sheet Cakes Are Baked

Sheet cakes are baked in the oven in large flat pans. These pans are typically called sheet pans or jelly rolls. Most home ovens will only fit quarter-sheet cakes and half-sheet cakes. Full-sheet cakes are typically too large to fit in a normal oven. 

Things To Consider When Making Sheet Cakes

When you are making a sheet cake, make sure to first consider the size, how many people you need to serve with the cake, and what size pieces you hope to cut the cake into. Once you know these things, select the correct size pan, and make your cake.

Tips And Tricks

Prevent it from Sticking. A great way to prevent your sheet cake from sticking to the pan is to use cooking spray on the pan before adding the cake.

Coat the pan with a light dusting of flour, or add a layer of parchment paper at the bottom of the pan before adding the cake batter. 

Layer if Desired. Because some sheet cakes are very thin, you can layer them together if desired. Simply add a bit of frosting or fruit in between the layers to help them stick together. 

Decorate Simply. Sheet cakes are great because they are so simple. You can also decorate them simply if desired. Usually, you will see sheet cakes with a plain layer of frosting and a border.

If you are feeling adventurous you can try making frosting roses for decorations or simply use other toppings to decorate.
