Jump to Recipe
Texas Sheet Cake is a Southern favorite: a thin, moist chocolate cake covered with a warm, fudgy frosting that sets as it cools. It is a go-to dessert for potlucks, family reunions and holidays.
It bakes in a large sheet pan and feeds a crowd, so there is plenty to share.
Why You’ll Love This Texas Sheet Cake
- Moist, fudgy chocolate flavor
- Feeds a crowd with one pan
- The warm frosting soaks into the cake
- A classic Southern potluck dessert
Ingredients You’ll Need
Use unsweetened cocoa powder and buttermilk for a tender crumb. Chopped pecans are traditional in the frosting but optional. Pour the frosting over the warm cake for the best texture.
How to Make Texas Sheet Cake
Boil butter, water and cocoa, then stir into the flour, sugar and buttermilk batter. Bake in a sheet pan. While it bakes, make the frosting, then pour it over the warm cake.
Tips for the Best Texas Sheet Cake
- Frost the cake while it is still warm
- Do not overbake, since this cake is meant to be moist
- Toast the pecans for extra flavor
- Use a 12 by 17-inch sheet pan
Variations
- Leave out the nuts
- Add a little cinnamon to the cake
- Use a splash of espresso to deepen the chocolate
How to Store and Reheat
Cover and keep at room temperature for 3 days or refrigerate for up to 5 days.
Why This Texas Sheet Cake Works
Texas Sheet Cake works because the batter is made on the stovetop with hot butter, water and cocoa, which blooms the cocoa and gives the cake a deep chocolate flavor and a very moist crumb. The batter is thin, so the cake bakes quickly in a large pan and stays soft and tender.
The frosting is poured warm over the warm cake, which is the secret to its signature texture. It soaks slightly into the top of the cake, then sets into a thin, fudgy layer that is almost like candy. Pecans add crunch and a toasty flavor.
Ingredient Notes and Substitutions
- Cocoa powder: Use unsweetened natural cocoa powder. Dutch-process cocoa also works but gives a slightly darker color
- Buttermilk: Gives tang and tenderness. Milk with a tablespoon of lemon juice is a fine substitute
- Butter: Use real butter in both the cake and the frosting for the best flavor
- Pecans: Toast them for 5 minutes in the oven for extra flavor, or leave them out for a nut-free cake
- Pan size: A 12 by 17-inch sheet pan gives the traditional thin cake. A 9 by 13 pan works but needs a longer bake
Common Mistakes to Avoid
- Overbaking, which dries the cake. The center should spring back when touched
- Letting the cake cool completely before frosting, which prevents the frosting from soaking in
- Overmixing the batter after adding the flour
- Using cold buttermilk or eggs, which can change the texture
What to Serve With Texas Sheet Cake
Cut the cake into squares and serve it with a scoop of vanilla ice cream or a glass of cold milk. It is a Southern favorite for church suppers, family reunions and summer barbecues because it feeds a crowd and travels well in the pan. Cover it tightly with foil, and it stays moist for days on the counter.
Frequently Asked Questions
Why is it called Texas sheet cake?
It is a Southern cake baked in a large sheet pan and its name nods to the big size of Texas.
Can I use a different pan?
A 9 by 13-inch pan works but the cake will be thicker and need more baking time.
Do I need buttermilk?
You can make a substitute with milk and a tablespoon of lemon juice.
Why is the frosting poured on warm?
Warm frosting spreads easily and soaks slightly into the cake. As it cools, it sets into the thin, fudgy layer that makes Texas sheet cake special.

Yes. It actually tastes better the next day. Store it covered at room temperature for up to 3 days or in the refrigerator for up to 5 days.
