How to Make Chocolate Peanut Butter Texas Sheet Cake Recipe
Step 1: Prepare Your Pan and Oven
Start by preheating your oven to 350°F. You’ll want to thoroughly grease a 13 x 18-inch jelly roll pan, either with butter or a baking spray like Baker’s Joy. This ensures the cake will release easily once baked, giving you clean edges and an attractive slice every time.
Step 2: Whisk Together the Wet Ingredients and Sugar
In a large bowl, combine your melted and cooled butter, whole milk, sour cream, and granulated sugar. Whisk these together until smooth and fully combined. This mixture creates the moist and tender foundation that sets this Texas sheet cake apart.
Step 3: Add Eggs, Vanilla, and Dry Ingredients
Whisk in the eggs and vanilla extract until incorporated. Follow this by whisking in the all-purpose flour, cocoa powder, baking soda, and salt. Be sure to mix just until you no longer see flour. This keeps the batter delicate for that soft, crumbly texture.
Step 4: Pour and Bake
Pour your silky batter evenly into the prepared pan and pop it into the oven. Bake for about 20 minutes, or until a toothpick inserted in the center comes out clean. The edges will be irresistibly fudgy while the inside remains tender.
Step 5: Let the Cake Cool
Once out of the oven, allow the cake to cool for 10 minutes in the pan. This short cooling window is essential before frosting, so the layers meld beautifully without melting or sliding.
Step 6: Make the Peanut Butter Frosting
In a medium bowl, beat together the creamy peanut butter with the softened butter, vanilla extract, salt, powdered sugar, and milk. Whip until smooth, thick, and spreadable. This is where that classic chocolate and peanut butter magic begins to shine.
Step 7: Spread the Frosting and Prepare the Chocolate Glaze
Evenly spread the peanut butter frosting over the warm cake—warm enough to slightly melt it, creating a dreamy, gooey layer. Next, combine the melted butter, milk, and light corn syrup in a saucepan. Stir in the dark chocolate and vanilla until melted and silky. Remove from heat and gradually whisk in the sifted confectioners’ sugar until smooth and glossy.
Step 8: Top with the Chocolate Glaze
Pour the warm chocolate glaze over the peanut butter layer and spread it evenly. Let the entire cake cool completely so the glaze sets with a shiny, chocolatey finish you won’t be able to resist slicing into.
How to Serve Chocolate Peanut Butter Texas Sheet Cake Recipe

Garnishes
For an extra special touch, sprinkle chopped roasted peanuts or a pinch of flaky sea salt on top of the chocolate glaze. This adds a delightful crunch and intensifies the peanut butter flavor, making every bite pop.
Side Dishes
This cake shines brilliantly all on its own but pairs wonderfully with a scoop of vanilla ice cream or a dollop of freshly whipped cream. If you want to keep things light, a fresh berry compote also cuts through the richness beautifully.
Creative Ways to Present
Serve this sheet cake in rustic squares on a wooden board for casual gatherings or cut into bite-sized bars for parties. You can even layer smaller pieces between sandwich cookies for an inventive dessert treat. No matter how you present it, this cake is a showstopper.
Make Ahead and Storage
Storing Leftovers
Keep leftovers tightly covered in an airtight container at room temperature for up to 3 days. The cake maintains its moist texture and luscious frosting during this time but can also be refrigerated if you prefer a firmer frosting.
Freezing
You can freeze the cake after baking and frosting by wrapping it well in plastic wrap and then foil. Freeze up to 2 months. When ready to enjoy, thaw overnight in the refrigerator to retain that fresh-baked flavor and creamy peanut butter layer.
Reheating
For best results, bring refrigerated or thawed cake to room temperature before serving. Avoid microwaving as the frosting can melt unevenly. Instead, slice and let sit on the counter for about 30 minutes for the perfect indulgence.
FAQs
Can I use natural peanut butter in this Chocolate Peanut Butter Texas Sheet Cake Recipe?
Natural peanut butter has a different oil content and texture, which might make the frosting thinner and harder to spread. If you use natural peanut butter, stir it well and consider reducing the milk slightly in the frosting to maintain thickness.
Is this cake gluten-free?
This traditional Chocolate Peanut Butter Texas Sheet Cake Recipe uses all-purpose flour, so it is not gluten-free. However, you can try substituting a gluten-free flour blend, but results may vary in texture.
Can I make this cake vegan?
Transforming this recipe into a vegan version would require several substitutions like plant-based butter, a non-dairy milk, and egg replacers. The texture and flavor might differ, but it’s worth experimenting if you need a vegan-friendly version.
How long does this cake stay fresh?
If stored properly at room temperature, the cake stays moist and tasty for about 3 days. Refrigeration can extend freshness up to a week but may slightly firm up the frosting layer.
Can I double the recipe for a bigger gathering?
Absolutely! Just use a larger sheet pan or two 13 x 18 pans. Keep in mind that baking times may increase slightly, so monitor the cake closely for doneness.
Final Thoughts
This Chocolate Peanut Butter Texas Sheet Cake Recipe is one of those special treats that’s effortless to make but feels like a celebration with every single bite. Whether you’re baking for family, friends, or just because you deserve a little joy, this cake delivers on every level—rich chocolate, creamy peanut butter, and that unforgettable Texas-sized charm.

- 1/3 cup milk
- 1/3 cup light corn syrup
- 1 tbsp vanilla extract
- 6 oz dark chocolate, chopped
- 3 cups confectioners’ sugar, sifted
Instructions
- Preheat Oven and Prepare Pan: Preheat your oven to 350°F (175°C). Grease a 13 x 18 inch jelly roll pan thoroughly with butter or use a non-stick spray like Baker’s Joy to ensure the cake doesn’t stick.
- Mix Wet Ingredients: In a large mixing bowl, whisk together the melted and slightly cooled butter, whole milk, sour cream, and granulated sugar until fully combined.
- Add Eggs and Dry Ingredients: Whisk in the eggs and vanilla extract. Then sift in and whisk together the all-purpose flour, cocoa powder, baking soda, and salt until the batter is smooth and even.
- Bake the Cake: Pour the cake batter evenly into the prepared jelly roll pan. Place in the oven and bake for about 20 minutes, or until a toothpick inserted into the center comes out clean. Remove from oven and let cool for 10 minutes in the pan.
- Prepare Peanut Butter Layer: While the cake slightly cools, combine creamy peanut butter, softened unsalted butter, vanilla extract, salt, powdered sugar, and regular milk in a bowl. Whisk or beat until smooth and creamy.
- Spread Peanut Butter Layer: Spread the prepared peanut butter mixture evenly over the warm cake directly in the pan, allowing it to soften the layer slightly and meld flavors.
- Make Chocolate Frosting: In a saucepan or microwave-safe bowl, melt the unsalted butter and chopped dark chocolate together until smooth. Stir in the milk, light corn syrup, and vanilla extract. Gradually whisk in the sifted confectioners’ sugar until the frosting is smooth and spreadable.
- Frost the Cake: Pour and spread the chocolate frosting evenly over the peanut butter layer while the peanut butter layer is still warm so that the layers meld together.
- Set and Serve: Allow the cake to cool and the frosting to set before slicing into 16 pieces. Serve and enjoy the combination of rich chocolate and creamy peanut butter flavors.
Notes
- Ensure the melted butter for the cake is cooled before mixing to prevent cooking the eggs.
- The jelly roll pan yields a thin, sheet-style cake typical of Texas sheet cakes.
- For a stronger peanut flavor, feel free to use natural peanut butter.
- The frosting sets best when spread over warm peanut butter layer but not too hot to melt the frosting excessively.
- Store leftovers covered at room temperature for up to 3 days or refrigerated for up to 5 days.
