Texas Sheet Cake made with peanut butter instead of chocolate! Wonderfully moist with a delicious peanut butter frosting!

Recipe Ingredients

  • 2 cups all-purpose flour
  • 2 cups white sugar
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • 1 cup water
  • ¾ cup butter or margarine, softened
  • ½ cup peanut butter
  • ¼ cup vegetable oil
  • 2 eggs
  • ½ cup buttermilk
  • 1 teaspoon vanilla extract
  • ⅓ cup white sugar
  • ⅓ cup evaporated milk
  • 1 tablespoon butter or margarine
  • ⅓ cup chunky peanut butter
  • ⅓ cup miniature marshmallows
  • ½ teaspoon vanilla extract

Cooking Directions

  1. 1 Preheat the oven to 350 degrees F (175 degrees C). Grease a 10x15x1 inch jellyroll pan.
  2. 2 In a large bowl, stir together the flour, 2 cups sugar, baking soda and salt. Set aside. Combine the water and 3/4 cup of butter in a saucepan, and bring to a boil. Remove from the heat and stir in 1/2 cup peanut butter and vegetable oil until well blended. Stir this mixture into the dry ingredients. Combine the eggs, buttermilk and vanilla; stir into the peanut butter mixture until well blended. Spread the batter evenly in the prepared pan.
  3. 3 Bake for 18 to 26 minutes in the preheated oven, or until a toothpick inserted near the center comes out clean.
  4. 4 While the cake bakes, place 2/3 cup sugar, evaporated milk, and butter in a saucepan. Bring to a boil, stirring constantly. Cook stirring for 2 minutes. Remove from heat and stir in the peanut butter, marshmallows and vanilla until marshmallows are melted and the mixture is smooth.
  5. 5 Spoon the frosting over the warm cake and spread in an even layer. Allow to cool before cutting and serving.

  1. PB sheet cake makes it to nearly every family function on my hubby's side. I am pregnant with a craving and there's no family event in sight. So I made my first ever pb sheet cake. The frosting is amazing. It makes the cake. Upon first bite I was slightly disappointed as the cake does - Read more ...
  2. Turned out GREAT (used a buttercream frosting that I added peanut butter to)- good peanut butter flavor. I was afraid it would be oily like previous reviewers but it wasn't. I did add about a 1/4 c. more peanut butter and cut oil to 1/8 c.
  3. Since peanut butter cakes can be dry I was encouraged to see that this recipe apparently took that into consideration by including a little oil. But it disappoints. The cake is a little on the oily side has a dense crumb and doesn't pack the peanut butter flavor I hoped for. The frosting recipe didn't - Read more ...
  4. This cake is pure heaven for the die hard peanut butter lover and is "oh so good" served with a tall glass of milk. I've been making this cake for a long time and I have to admit that I've never been able to get consistent results. My biggest problem is with it falling in - Read more ...
  5. Really good! I made this for work and it was well received. I made it as written except that I doubled the icing. Because so many reviewers commented that the peanut butter flavor was somewhat subtle, a couple even saying the cake was bland, I was a bit concerned that it wouldn't be peanut buttery - Read more ...
  6. This cake is wonderful!!! Rich and moist and flavorful! I used two sticks of margarine instead of butter and oil and baked it in a 9x12 pan - came out LOVELY! Great with fudge frosting!
  7. Everyone has to try this cake. This is one of the best cake receipes I have ever made. I agree that the peanut butter is not overwhelming. I didn't have marshmallows in my cupboard but I did have marshmallow cream and used it instead. Wonderful result. The cake has the taste of mild peanut butter - Read more ...
  8. This is delicious. Just as moist and rich as the original chocolate version. I did make one modification, I used two sticks of butter rather than part butter part oil. If you have never made a Texas Sheet cake, do not be scared by the consistency of the batter, it WILL bake up correctly. Be - Read more ...
  9. This is a great cake. If you love peanut butter this one is perfect. I made it for work and it was gone by lunch and I made another one the same night because it is an easy cake.
