What is a Sheet Cake?

A sheet cake is a cake that is baked in a rectangular, flat sheet cake pan. Sheet cakes are also known as “slab cakes” to some. They can be served with frosting on top or layered with a filling and then frosted.

What is a Half Sheet Cake?

As the name suggests, a half sheet cake is simply half of a full sheet cake. You can make a half sheet cake using a half sheet cake pan or cut a full sheet cake in half to get two half sheet cakes.

Half Sheet Cake: Benefits

Sheet cakes are a crowd favorite, perfect for gatherings with a lot of people as they are much easier to cut and portion out. The flat top gives you lots of room to decorate and customize with words.

Half sheet cakes are relatively effortless to make, making them one of the more affordable cake options for larger crowds.

Half Sheet Cake: Pan Sizes & Dimensions

Depending on the manufacturer of your cake pan, the size of your half sheet cake can vary slightly. Half sheet cake pans usually measure 18” x 12”. Half sheet cakes sold at most bakeries and grocery stores measure 15” x 11” with an average height of 2”, give and take an inch.

How you decide to decorate your cake also plays a role in determining how big your final cake will be. Some like to trim off the edges of the cake making it smaller, while others like to apply a thick layer of frosting which would make the cake slightly larger.

Half Sheet Cake: Servings

Typically speaking, a single layer half sheet cake can serve up to 40 people. Of course, the bigger each individual slice means the fewer pieces you will yield.

A sheet cake slice can range from being 1” x 2”, 2” × 2” to 2” × 3”. They will serve 36, 54, or 108 servings respectively.

How to Decorate a Half Sheet Cake?

Half sheet cakes are most commonly decorated with buttercream frosting or ganache. Given its flat surface, you can easily achieve a smooth-frosted look by spreading your frosting evenly on all five sides of the cake, though i personally prefer a more textured rustic look.

After you’ve covered up all sides of the cake, you can use the remaining frosting to give your cake a nice border. You can do so by piping along the edges of the cake using your choice of a piping tip. I suggest a 1M star tip or a 6B french star tip.

The border will act as a nice frame for any writing or edible printed picture you want to put on the cake. If a bordered look isn’t your cup of tea, another easy way to decorate your half sheet cake is to pipe rosettes all over it. This is a super easy way to give your homemade cake that professional look.

As with any cake, you’d always want to present it on a cake board. I always recommend using a waxed, grease-resistant board to prevent your cake from sliding.

Make sure to size up a little when choosing your box and your board to prevent damaging your cake. Trust me, you do not want all that hard work you put into piping the borders and frosting to go to waste. Go for something that is around 19″ x 14″ x 4″.

How to Make a Half Sheet Cake: Recipes

While you can find sheet cake recipes on the internet, you don’t get a great variety of selections.

But fear not! All you need to look for is any layer cake recipe that yields 16 cups of batter, which would be the equivalent of three 10” round cake layers. You can refer to this guide if you need more help with conversion.

How to store a half sheet cake?

You can store an unfrosted half sheet cake by wrapping it tightly in plastic wrap and freezing it. A frosted half sheet cake (decorated without fresh ingredients) can stay at room temperature for up to four days, just make sure to cover it in a bowl or packaging that will prevent dust or any other particles from reaching it.

If you are to freeze a frosted half sheet cake, leave it in the fridge for 15 minutes before wrapping it and putting it in the freezer. This will help the frosting harden and not get easily damaged by the wrapping process.

Wrapping the cake, freezing it, or leaving it out at room temperature all prevents the cake from drying out. A frozen sheet cake can last in the freezer for up to one year. You can store your cake in the refrigerator as well but it will be at risk of drying out.
