What Is A Texas Sheet Cake?

A Texas sheet cake is a type of chocolate cake that is large, thin, and rectangular in shape.

It’s known for its rich, moist, and dense texture, as well as its distinctive feature: a poured chocolate frosting that’s spread over the warm cake while both are still in the baking pan.

Using a different sized sheet pan will result in changes to the thickness of the cake and may need the cooking time adjusted.

STEP TWO: In a large bowl, combine your all-purpose flour, sugar, and salt.

STEP THREE: In a large saucepan over medium-low heat, melt your butter. Add your cocoa powder and whisk together.

Add the boiling water and whisk it into the butter mixture.

STEP FOUR: In a separate small bowl, combine your buttermilk, eggs, baking soda, and vanilla, then whisk together.

Stir the buttermilk mixture into the chocolate mixture and whisk together. Mix with the dry ingredients (flour, sugar, and salt).

STEP FIVE: Pour batter into the sheet cake pan and bake for 20 minutes.

Remove the pan from the oven and poke to make fork holes across the top of the entire cake so that the yummy frosting soaks down into the cake just a little bit.

PRO TIP:

A fork or a wooden barbecue skewer is the perfect width for the holes in the cake.

STEP SIX: While your cake bakes, start your chocolate frosting by melting your butter in a large saucepan over medium-low heat.

Add your cocoa powder and whisk together. Turn off the heat.

Add your milk, vanilla, and powdered sugar (sift it in while whisking instead of just dumping all of it in at once). Stir until no lumps remain.

STEP SEVEN: Pour your frosting over your warm cake and let cool for about 10 to 15 minutes before serving, if you can wait that long!

PRO TIP:

When you’re pouring the cream into the holes, tap the pan on the counter a few times to get rid of any air bubbles and make sure the frosting fills the holes completely.

Texas Chocolate Sheet Cake FAQs

What is a sheet cake?

The main difference between a sheet cake and a regular cake is the pan that they are baked in. Sheet cakes are baked in a large pan specifically sized and named ‘sheet cake pans.’ They are large, flat pans and are 18 x 13 inches. This makes sheet cakes a great alternative for feeding a large group of people.

How many people will a sheet cake feed?

Depending on the size of the pieces, a sheet cake can feed up to 48 people.

How do I store a sheet cake?

Sheet cakes can be stored on the counter for up to five days at room temperature. If you are thinking of storing leftovers longer, you can slice them up (or store them whole) and freeze the cake in an airtight container for up to two months.

What size pan for Texas sheet cake?

The typical size pan for making a Texas Sheet Cake is an 18 x 13-inch rimmed baking sheet or jelly roll pan. This pan size is large and shallow, which allows the cake to spread out into a thin layer, characteristic of a Texas sheet cake.

How do I adjust the time for other size pans?

When adjusting the baking time for a different size pan, it’s important to consider the area of the pans. The goal is to maintain a similar cake thickness to ensure even baking. It’s always a good idea to monitor the cake closely as it bakes and use visual cues and testing to determine when it’s done.
