Texas Sheet Cake made with peanut butter instead of chocolate! Wonderfully moist with a delicious peanut butter frosting!
Peanut Butter Sheet Cake
2 cups all-purpose flour
2 cups white sugar
1/2 teaspoon baking soda
1/4 teaspoon salt
1 cup water
3/4 cup butter or margarine, softened
1/2 cup peanut butter
1/4 cup vegetable oil
1/2 cup buttermilk
1 teaspoon vanilla extract
2/3 cup white sugar
1/3 cup evaporated milk
1 tablespoon butter or margarine
1/3 cup chunky peanut butter
1/3 cup miniature marshmallows
1/2 teaspoon vanilla extract
1 Preheat the oven to 350 degrees F (175 degrees C). Grease a 10x15x1 inch jellyroll pan.
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 Bake for 18 to 26 minutes in the preheated oven, or until a toothpick inserted near the center comes out clean.
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 Spoon the frosting over the warm cake and spread in an even layer. Allow to cool before cutting and serving.
