Chocolate Peanut Butter Sheet Cake
When I first moved to Texas, my mom and I ate lunch every Friday together. At first we tried out different local spots, but eventually we settled on one go-to place for our weekly lunches: a Texas home-cooking restaurant called The Picket Fence.
Aside from the Texas Cheese Steak which was to-die-for, it was the dessert tray that kept me coming back for more. Each week there were at least 10 different freshly baked desserts, like Italian Cream Cake and Texas Sheet Cake, up for grabs. But you had to get there early or they would run out!
This was my first taste of a real Texas sheet cake and it was one of my favorites! Earlier this year I published a Texas Sheet Cake Cookies recipe inspired by my favorite Texas treat, and I couldn’t believe the response! It’s gone viral over and over again and so many readers have taken the time to let me know that they enjoyed the cookies.
Seriously, that is the best part of this blogging thing! Ok, that and wearing pajamas every day to work!
Since I’m a HUGE peanut butter fan too, I’m so excited about this Chocolate Peanut Butter Texas Sheet Cake! I mean, just look at it! I can’t even look at the photos without drooling!

How to Make Peanut Butter Sheet Cake
To Make the Cake:
Preheat oven to 350°F and prep your pan with non-stick spray. Whisk together cake ingredients and pour into your prepared pan.
Traditionally, a Texas sheet cake is baked on a jelly roll pan. However, if you don’t have one on hand you can use a regular baking dish for a thicker cake (like our Thick and Fluffy Texas Sheet Cake Recipe):
Keep in mind that using a smaller pan may increase cooking time slightly, so keep an eye on it while baking.
Approximate Baking Times:
- 13 x 18″ jelly roll pan: 20 minutes
- 9 x 13″ baking dish: 25 minutes
To Make the Peanut Butter Frosting:
Add peanut butter and regular butter to a large mixing bowl and use a stand mixer or electric hand mixer to cream until smooth. Add vanilla and salt and continue mixing.
Next you’ll add the powdered sugar, one half cup at a time, while mixing on medium speed. Scrape down the side of the bowl as needed to make sure everything is well incorporated.
When all sugar has been mixed in, the peanut butter icing may seem a bit dry — don’t worry! Add milk, one teaspoon at a time, and beat at medium speed until light and fluffy.
Spread one thick and even layer of peanut butter fudge on the top of the cooled cake.
To Make the Chocolate Frosting:
This boiled chocolate frosting sort of a combination of chocolate ganache and chocolate buttercream. It’s amazing!! Rich and fluffy at the same time!
To start, combine butter, milk, corn syrup, and vanilla extract in small saucepan over medium heat, stirring until butter is melted. Next, lower the heat to avoid boiling or bubbling and add the chocolate, whisking constantly until melted and smooth.
Remove pan from heat, add the powdered sugar, and whisk until incorporated. Let the chocolate glaze sit for 5 minutes until it begins to cool and thicken.
Slowly pour glaze on top of the peanut butter fudge layer and use a spatula to gently spread the frosting towards the edges. Allow chocolate glaze to set for about 30 minutes.
