Ingredients
For the Chocolate Cake
- 2 cups all-purpose flour
- 2 cups granulated sugar
- 1/4 teaspoon salt
- 1 teaspoon baking soda
- 1/2 cup unsalted butter
- 1/2 cup vegetable oil
- 1/4 cup cocoa powder
- 1 cup water
- 1/2 cup buttermilk
- 2 large eggs
- 1 teaspoon vanilla extract
For the Peanut Butter Layer
- 1 cup creamy peanut butter
- 1/2 cup powdered sugar
- 4 ounces cream cheese, softened
- 1/4 cup heavy cream
For the Chocolate Frosting
- 1/2 cup unsalted butter
- 1/4 cup cocoa powder
- 1/3 cup milk
- 3 cups powdered sugar
- 1 teaspoon vanilla extract
- 1/2 cup chocolate chips
- Chopped peanuts and mini chocolate chips for topping
Instructions
Preheat your oven to 350°F and grease a 10×15-inch sheet cake pan. Texas sheet cakes are traditionally baked in a large shallow pan, which helps create a thin, moist cake with lots of frosting in every bite.
In a large mixing bowl, whisk together the flour, sugar, salt, and baking soda until combined.
In a saucepan over medium heat, combine the butter, vegetable oil, cocoa powder, and water. Stir continuously until the butter melts and the mixture becomes smooth and hot, but not boiling.
Pour the warm chocolate mixture into the dry ingredients and stir gently until combined.
Add the buttermilk, eggs, and vanilla extract. Mix until the batter becomes smooth and glossy. Do not overmix because that can make the cake less tender.
Pour the batter into the prepared sheet pan and spread evenly.
Bake for 18 to 22 minutes or until a toothpick inserted into the center comes out with a few moist crumbs attached.
Allow the cake to cool completely before adding the peanut butter layer.
For the peanut butter filling, beat together the peanut butter, powdered sugar, cream cheese, and heavy cream until smooth and fluffy. Spread evenly over the cooled cake.
To prepare the frosting, melt the butter in a saucepan and whisk in the cocoa powder and milk until smooth. Remove from heat and gradually whisk in the powdered sugar and vanilla until creamy.
Let the frosting cool slightly, then spread it carefully over the peanut butter layer. Sprinkle with chocolate chips and chopped peanuts while the frosting is still soft.
Refrigerate the cake for at least 1 hour before slicing so the layers can fully set.

- Use room temperature cream cheese for a smoother filling
- Allow the cake to cool fully before adding the peanut butter layer
- Slightly cool the frosting before spreading to avoid melting the filling

FAQs
What makes a Texas Sheet Cake different from regular cake?
Texas sheet cake is baked in a large shallow pan, which gives it a thinner, extra-moist texture with a generous amount of frosting in every bite. It is known for being rich, soft, and easy to serve to a crowd.
Can I make Chocolate Peanut Butter Texas Sheet Cake ahead of time?
Yes, this cake tastes even better after chilling because the layers become firmer and the flavors blend together beautifully. It can easily be made one day ahead and stored covered in the refrigerator.
Can I freeze this cake?
Absolutely. Slice the cake into portions and freeze individually wrapped pieces for up to 2 months. Thaw overnight in the refrigerator before serving.
Can I use natural peanut butter?
You can, but regular creamy peanut butter usually creates a smoother and more stable filling. Natural peanut butter can sometimes separate and make the layer softer.
How do I keep the frosting smooth?
Allow the frosting to cool slightly before spreading, but not too much or it will begin to thicken. An offset spatula works best for creating an even bakery-style finish.
