The Very Best Texas Sheet Cake Recipe
Maybe you think I’m exaggerating up there. Calling this the “best” Texas Sheet Cake. But just wait until you try it! While these popular cakes generally follow a standard recipe and there isn’t a lot of room for deviation (not if you want to call it a true Texas Chocolate Sheet Cake, anyway), I’ve made a few adjustments to this classic cake that make it better than any you’ve tried before.
Here’s what we did differently:
- Increased Moisture: My chocolatey cake base is made with a combination of brown sugar and white sugar; the added brown sugar adds moisture and richness to the cake.
- Enhanced Flavors: A splash of vanilla adds a depth of flavor, and a sprinkle of instant coffee grounds doesn’t make the cake taste like coffee but enhances the rich chocolate tones (I use this same technique to add flavor to my popular chocolate cupcakes and it’s also used in this chocolate poke cake!).
- Extra Chocolate-y: The chocolate flavor is amped up thanks to extra cocoa powder in the batter. Texas Sheet Cake is a chocolate-lover’s dream.
This recipe is believed to have southern origins (some of my most favorite recipes do, like peanut brittle and hush puppies!) but there’s some debate on whether or not that’s actually true or not… more on that below!

Why Is It Called A Texas Sheet Cake?
As it turns out, the history behind the name is actually pretty unclear. Some cake historians argue that it’s named for its size. A Texas Sheet Cake is baked in a 10×15 jelly roll pan, making it larger than your average cake!
It’s questionable where the cake even originated, it might not have been in Texas at all! If you have any knowledge of or ideas about where the name came from, I’d love to hear it in the comments!
Does Texas Sheet Cake Need to Be Refrigerated?
This Texas Sheet Cake does not need to be refrigerated and will keep at room temperature for several days. Store it covered or in an airtight container so it doesn’t dry out.
If you need to store this cake longer, it can be kept refrigerated, but keep in mind that refrigerators tend to dry out cake, even if the cake is stored in an airtight container.
Can You Freeze Chocolate Sheet Cake?
You sure can. Cool the Texas Sheet Cake completely, then cover with plastic wrap. It will keep well for about 2 months in the freezer. Allow to come to room temperature before serving.
Making a Texas Sheet Cake from scratch is easy and delicious! Make two; one for now and freeze one for later!
