Best Chocolate Sheet Cake Recipe
I’ve tried my fair share of recipes for Texas Sheet Cake over the years. And honestly, I have never had a bad one. I mean, what’s not to love? Moist chocolate cake, coated in thick warm chocolate frosting, and sprinkled with chopped nuts. It’s seriously difficult to screw one up.
There are about as many Texas Sheet Cake recipes in existence as there are chocolate chip cookies. Some use sour cream, others use buttermilk. Some use a 15×10 pan, others use an 18×12. And most require the batter and frosting to be made in a saucepan. But this particular recipe is the bee’s knees, made with buttermilk, cinnamon, toasted pecans, and no need for the stovetop, so less dishes to clean!
What is Texas Sheet Cake?
I assumed it originated in Texas…because DUH. But after some Google research, it wasn’t entirely clear.
Some say it’s simply because the cake is large, like the state of Texas. Others say it’s because of the addition of buttermilk (a Texan’s favorite ingredient), and pecans in the icing (which are native to south central North America, Texas in particular.) The recipe is also similar to one featured in the Dallas Morning News in 1957 that ended up taking the country by storm. It has also been suggested that Lady Bird Johnson was involved somehow, but historians combed the LBJ archives in Austin and couldn’t find any evidence of this.
The cake became popular in the South in the 1950’s just after German’s Chocolate Cake became well known. The Texas Sheet Cake is similar in flavor, but way easier to prepare, making it gain huge popularity nationwide.
So who really knows. Some history is concrete, some not so much. I say it’s a called a Texas Sheet Cake because it’s rich, bold, and cannot be ignored when entering a room – like a Texan! HA.
Why We Love It:
- It’s pretty hard to mess up! Sure, you still have to follow the ingredients and directions perfectly, as with any cake (baking is a science, after all!) But this sheet cake is pretty fool proof.
- Single layer for the win. Because it’s flat, it cooks evenly all around. And it’s modest 1-2 inch height makes it easy to frost. Nothing a mile high, fancy, or complicated.
- Sheets cakes are extremely portable. You don’t need to worry about them falling over on that long car ride to Aunt Betsy’s. And if your jelly roll pan comes with a lid, even better! They’re the perfect dessert to take to any potluck.
- The frosting. Goodness, THAT frosting. It’s like nothing else, and what really separates Texas Sheet Cake from other chocolate cakes. With most cakes, you need to wait for them to cool completely before frosting, but not with a Texas Sheet Cake. This baby requires the cake and the frosting to still be warm, or you won’t be able to spread it. The frosting actually acts as a barrier, protecting the cake from air and moisture, allowing the cake to sit out at room temperature (wrapped and covered) for about 4 days and still be delicious and safe.
Tips for Success
- Do not make the frosting in advance. The frosting hardens fast! So don’t make that in advance. I suggest whipping it up right before you’re going to use it, then pour and spread with even strokes, followed by immediately sprinkling the pecans on top.
- Let the cake cool a bit before frosting. While it is important to pour the frosting over a warm cake, I prefer to let the cake cool for 8-10 minutes beforehand, otherwise the frosting completely absorbs into the cake and doesn’t leave that awesome thick, fudgy layer that is such a key component.
- The size of your jelly roll pan does matter. A 13×9 pan will render a thicker cake, 18×12 (which is a half baking sheet) a super thin cake, and a 15×10 is perfect IMHO! Not too thick, not too thin. Baking times, if using something other than the 15×10 in this recipe, will vary.

Proper Storage
- Does Texas sheet cake need to be refrigerated? Unless your kitchen is hot and humid, the cake can sit out at room temperature, wrapped and covered, for up to 4 days. After that it needs to be refrigerated.
- Can I freeze Texas sheet cake? Yep! You can freeze the cake after it has been made and iced. Leave the cake in the baking sheet, let it cool completely. Then cover with plastic wrap, then in foil. It can be frozen for up to 1 month. Thaw in the fridge overnight.
