A quarter sheet cake pan’s dimensions are 13 * 9 inches and one to two inches deep. A standard commercial oven can fit four quarter size sheet pans.

Measure with a Measuring Stick

An easy way to know the pan’s dimensions is to measure it from the inside edges with a measuring stick.

Place the stick against the pan’s bottom to know its length and width dimensions and measure up to ¼ inch for depth.

Measure with  Water

You can also test your pan’s volume.

Fill the pan to the rim with water, and put it into a measuring cup. A quarter sheet cake pan will hold up to 12 cups of water, which will help you know the pan’s volume.

However, do not put that much batter in the pan, as it will overflow.

What to Use to Decorate a Quarter Sheet Cake?

sheet cake decoration

There are many ways to decorate a quarter sheet cake. However, most of them are usually decorated with buttercream frosting.

Here are some popular ways for you to decorate your quarter sheet cake;


You only need a few ingredients to make the buttercream: butter, a few drops of milk, icing sugar, and flavored extract.

Buttercream is popular since it can be made into different flavors and colors and presented in various ways, such as swirls and a smooth finish.


Chocolate is one of the easiest ways to decorate your sheet cake. You can use cocoa powder as light dusting or melt chocolate with cream to make a ganache.

Note that white chocolate melts faster than dark chocolate as it contains more sugar. Therefore, keep it on low heat.


You can use fresh fruits and berries to decorate your quarter sheet cake. These include blueberries, raspberries, and strawberries.

When using fresh fruit, we recommend you add them at the last minute.

Edible Flowers

Flowers are an interesting way to decorate your quarter sheet cake. They include rose petals and lavender.

However, unless you know they are edible, do not eat them.


Desiccated coconut is a healthier alternative to sprinkles. Use light buttercream on your cake and add coconut.

Coconut is light and can be added to several flavors, including carrot, lemon, or chocolate cakes.


If you are in a hurry, then spreads are the perfect way to decorate your cake. You can use your daily spreads such as Nutella and marmalade. Or top it with fresh fruit or sprinkles.

Note that the cake has to be slightly warm if you use Nutella or peanut butter as it will melt, making it easy to decorate.


You can also use whipped cream to decorate your cake. However, ensure that you store the cream in the fridge and add it at the last minute.

Icing Sugar

If you do not want complex techniques, icing sugar is your best choice. Once the cake is cool, dust your cake with icing sugar paste.

Do not do it when the cake is hot, as the icing sugar will melt.


Drizzle caramel sauce on the cake or add it to cream cheese for a caramel frosting.

Whether looking for something festive or straightforward, the above ingredients will allow you to decorate your quarter sheet cake efficiently.

FAQs About Quarter Sheet Cake

How much cake do I need for 25 guests?

For 25 guests, a 10-inch cake will be enough. Therefore, a quarter sheet cake is perfect for around 25 guests, each getting a reasonable portion.

However, a half sheet cake will be your best option if you want bigger portions and some leftovers.

How do you cut a quarter sheet cake?

With a sharp knife, start cutting from the outside to the inside. Cut a horizontal line from the edge of the cake to the center.

Next, cut depending on the size you want based on the occasion (number of people). For example, a 1 * 2 cake should give you around 54 servings, while a 2* 2 cake will have 24 servings.

Once done, use a small spatula to lift the pieces off. Clean your knife with a hot napkin after each cut to ensure you get clear lines.

How much does a 2 Layer half sheet cake feed?

A double layer half sheet cake serves about 60 to 70 people, while a single layer can feed 18 to 40 people.

If you have more guests, opting for a double layer instead of a single one is best.
