Peanut Butter Texas Sheet Cake topped with peanuts and chocolate

As I’ve told you before, I am a big fan of one-layer cakes. Elaborately frosted, tiered cakes are not my favorite things to make. Luckily, you don’t need to make that kind of effort to make a beautiful cake.

I’ve had Texas Sheet Cakes before, but they’ve always been chocolate. This one, however, is all about peanut butter. If you love peanut butter like I do, you’ll be happy to know that there is peanut butter in both the cake and the icing.

Peanut Butter Texas Sheet Cake is a must-bake dessert for peanut butter fans. Great for feeding a crowd! - Bake or Break

Of course, it’s hard to resist adding a little chocolate to anything peanut butter. So, a little chopped chocolate on top sweetens things up a bit. For peanut butter purists, just leave off the garnish or double up on the chopped peanuts. Chopped peanut butter cups would be fabulous, too.

This sheet cake is a great cake for feeding a crowd. It’s a thin cake, but it’s big on flavor. You’ll have plenty to go around.

Peanut Butter Texas Sheet Cake is a must-bake dessert for peanut butter fans. Great for feeding a crowd!

For the cake:

  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup unsalted butter
  • 1 cup water
  • 1/4 cup creamy peanut butter
  • 1/2 cup buttermilk
  • 2 large eggs, lightly beaten
  • 1 teaspoon vanilla extract

For the icing:

  • 1/2 cup unsalted butter
  • 1/4 cup creamy peanut butter
  • 1/3 cup + 1 tablespoon milk
  • 16 ounces confectioners sugar
  • 1 teaspoon vanilla extract
  • 1/3 cup coarsely chopped peanuts
  • 1/3 cup coarsely chopped milk chocolate


To make the cake:

  1. Preheat oven to 350°F. Grease a 15″x 10″ jellyroll pan.
  2. Whisk together the flour, sugar, baking soda, and salt in a large mixing bowl. Set aside.
  3. Place the butter, water, and peanut butter in a medium saucepan. Cook over medium heat, stirring occasionally, until the mixture boils. Add to the flour mixture, and mix until combined.
  4. Combine the buttermilk, eggs, and vanilla. Stir into the cake mixture, mixing well.
  5. Spread the batter evenly in prepared pan. Bake 25-28 minutes, or until the edges are browned and a pick inserted into the center comes out clean.

To make the icing:

  1. Place the butter, peanut butter, and milk in a medium saucepan. Cook over medium heat, stirring occasionally, until the mixture boils.
  2. Remove from heat. Stir in the confectioners’ sugar and vanilla until smooth and spreadable.
  3. Pour the icing over the top of the warm cake and spread evenly. Garnish, if desired, with peanuts and chocolate.*


*I recommend that you add the garnish while the icing is still a bit warm so that the garnish will stick to the icing better as it sets.

  1. Can I bake this in a 9×13 pan do you think? I don’t have a 10×15.

  2. Looks lovely!! We love peanut butter anything!!

  3. *claps* yayy! I love any pb/chocolate combo!

  4. Yummm I bet this would be great with a chocolate ganache!

  5. Texas sheet cake has always been a favorite but to make it a peanut butter one…. Nothing could be more perfect! This time I will skip the choc and go pure peanut butter, too. My son would love this, so I will send him the recipe as well.

  6. I bet this is tasty. I love a sheet cake for a crowd!

  7. Yummy! I have never had Texas Sheet Cake, but I adore anything peanut butter chocolate- so I’m sure I would love this. 🙂

  8. Honestly, I’d have this peanut butter cake over a chocolate cake any day!

  9. I love one layer cakes. So much easier! This cake looks SO good. I can almost smell it!

  10. Catherine, using a 9″x 13″ pan will make this cake thicker, so you may need to bake it a bit longer. My only concern would be that the edges might get overbaked before the center can bake thoroughly. You could shield the edges with foil if necessary.

  11. This is definitely a keeper, good for so many summer bbq’s!

  12. Do you think that I could successfully cut this recipe in half? I don’t need a serve a crowd, but this cake sounds too delicious to pass up! What size pan do you suggest?

  13. I love sheet cakes and this ones flavours sound really good!

  14. Um how did I miss this recipe from you?! I love sheet cakes as well because you can whip them up in very little time and uses up ingredients you have laying around (like my bananas. Ooo banana peanut butter cake…)
