Ingredients You’ll Need

The ingredients for this Chocolate Peanut Butter Texas Sheet Cake may be simple, but each one brings something crucial to the table—whether it’s the moistness from sour cream, deep cocoa flavor, or the irresistible richness of peanut butter. Don’t skip or swap anything unless you really have to; classic ingredients are what make this cake magical.

• Unsalted butter: Delivers richness and ensures the cake and frostings stay velvety and moist.
• Whole milk: Adds tenderness and balances the sweetness throughout the cake and frostings.
• Sour cream: Gives the cake a beautiful crumb and subtle tang that complements the chocolate.
• Granulated sugar: Sweetens the cake without overpowering, helping with texture too.
• Large eggs: Bind the batter and add richness—make sure these are at room temperature for best results.
• Vanilla extract: Amplifies all the warm, cozy flavors in every layer of this classic sheet cake.
• All-purpose flour: The foundation that gives structure to the cake without weighing it down.
• Cocoa powder: Offers deep chocolate flavor—be sure to use a good quality, unsweetened variety.
• Baking soda: Lifts the cake so it bakes up perfectly light and tender.
• Salt: Balances flavors and sharpens the chocolate and peanut butter notes.
• Creamy peanut butter: Delivers pure, smooth peanutty goodness for that signature middle layer.
• Extra unsalted butter (peanut butter layer): Keeps the peanut butter filling fluffy and spreadable.
• Powdered sugar: Used in the peanut butter filling and the frosting, creating that creamy, sweet-smooth finish.
• Regular milk (peanut butter layer): Softens the peanut butter layer, making it luxuriously creamy.
• Light corn syrup: Helps the chocolate frosting stay glossy and pourable.
• Chopped dark chocolate: Adds intensity and an extra layer of real chocolate flavor to the frosting.
• Confectioners’ sugar (frosting): Sifted to avoid lumps, this makes the frosting cloud-like and luscious.

How to Make Chocolate Peanut Butter Texas Sheet Cake

Step 1: Preheat and Prep

Begin by cranking your oven to a toasty 350°F. Don’t skip greasing your trusty 13×18 jelly roll pan—that’s what makes those sheet cake edges perfectly caramelized and promises easy slicing later. A swipe of butter or a good spray with Baker’s Joy will have you covered.

Step 2: Make the Cake Batter

In a large mixing bowl, whisk together the melted (don’t forget to let it cool a bit!) butter, whole milk, sour cream, and sugar until everything looks smooth and glossy. Add your eggs and vanilla, then whisk again like you mean it. Sift in the flour, cocoa powder, baking soda, and salt; whisk until just combined so your cake stays tender. The batter should be silky, thick, and utterly tempting even before it’s baked.

Step 3: Bake

Pour your chocolate batter evenly into the prepared pan, smoothing the top with a spatula for that flawless finish. Slide it into the oven and bake for about 20 minutes—just until a toothpick poked into the center comes out with a moist crumb or two. Let the cake cool for 10 minutes before you start thinking about rich layers to come.

Step 4: Prepare the Peanut Butter Layer

Now comes the magic for peanut butter lovers. In your stand mixer or with a trusty hand mixer, cream the peanut butter and softened butter until they’re dreamy and smooth. Add the vanilla extract and salt, then blend again. Gradually mix in the powdered sugar; don’t worry if it looks a little dry. Add regular milk—just a teaspoon at a time—until the mixture becomes fluffy, spreadable, and holds its shape. Spread this luscious filling all over your slightly cooled cake, reaching right out to the edges.

Step 5: Make the Chocolate Frosting

In a medium saucepan over gentle heat, bring together the melted butter, milk, corn syrup, and vanilla extract. Stir until heated through, then add the chopped dark chocolate and stir again until everything is perfectly melted and smooth. Off the heat, whisk in sifted confectioners’ sugar and let the frosting stand for five minutes; it’ll thicken just enough for the perfect pour.

Step 6: Frost and Finish

Take a moment to admire your layered masterpiece, then pour that warm chocolate glaze slowly over the peanut butter layer. Use an offset spatula to nudge the topping to every corner—don’t rush, this is the crowning glory. Let the frosting set for about half an hour before slicing the Chocolate Peanut Butter Texas Sheet Cake into generous squares to share (or savor alone).

How to Serve Chocolate Peanut Butter Texas Sheet Cake

Garnishes

Dress up each square with a sprinkle of flaky sea salt, a handful of crushed peanuts, or even a few mini chocolate chips for extra crunch and flair. If you’re feeling fancy, a swirl of whipped cream or a drizzle of caramel sauce can turn each bite into something extra special.

Side Dishes

Balance the richness of this decadent dessert with a scoop of vanilla ice cream, fresh berries, or a tall glass of ice-cold milk. For an added treat at parties, a strong cup of coffee or a creamy latte makes a wonderful pairing with the deep flavors of this Chocolate Peanut Butter Texas Sheet Cake.

Creative Ways to Present

Serve the cake in traditional squares, stack smaller pieces on a tiered dessert stand, or try cutting rounds with a biscuit cutter for playful, bite-sized treats. For celebrations, arrange the pieces on a platter with seasonal fruit and edible flowers for a festive dessert table centerpiece.

Make Ahead and Storage

Storing Leftovers

Leftover Chocolate Peanut Butter Texas Sheet Cake keeps beautifully! Just cover your pan tightly with foil or transfer slices to an airtight container. Store at room temperature if you’ll finish it within two days, or refrigerate for up to five days for longer freshness—the flavors get even better.

Freezing

Want to save some cake for later? Chocolate Peanut Butter Texas Sheet Cake freezes like a dream. Once completely cooled and set, cut into portions, wrap each piece tightly in plastic wrap, and pop them in a freezer-safe bag or container. They’ll keep for up to three months—just thaw on the counter for a few hours whenever a craving strikes.

Reheating

To bring chilled or frozen cake back to its gooey, just-made glory, let individual pieces come to room temperature. For that fresh-from-the-oven finish, microwave single slices for 10–15 seconds—just enough to soften the peanut butter and make the frosting gloss up once again without melting everything completely.

FAQs

Can I use natural peanut butter instead of regular creamy?

Natural peanut butter can be used in a pinch, but the consistency is usually runnier and doesn’t hold its shape as well in the middle layer. For the best structure and classic taste, stick with regular creamy peanut butter.

Can I make this as cupcakes or in a different pan?

Absolutely! If you don’t have a jelly roll pan or want to make individual portions, cupcake tins or a 9×13-inch pan work well—just keep an eye on baking time and check for doneness with a toothpick.

How do I make sure the chocolate frosting is glossy and smooth?

Gently heating the frosting ingredients and letting the finished glaze rest for a few minutes ensures that gorgeous sheen. Using sifted confectioners’ sugar and quality chocolate also makes all the difference.

Can I make the layers ahead of time?

Yes! Bake the cake layer and prepare both frostings in advance, then chill until you’re ready to assemble. This works especially well if you’re prepping for a party—just bring everything to room temperature before spreading for best results.

What if I don’t have light corn syrup for the frosting?

If you’re out of light corn syrup, you can substitute an equal amount of honey or golden syrup. It won’t affect the taste too much but helps keep the chocolate topping soft and shiny.
