This scrumptious Peanut Butter Cake is a moist tender sheet cake topped with an easy creamy six ingredient peanut butter frosting. The end result is pure peanut butter nirvana and a true friend and family favorite. It stays fresh for days making it the perfect cake for potlucks and family reunions. With the exception of my son my family just loves peanut butter. I mean like we adore it. Peanut Butter Banana Bread, Mini Peanut Butter Cheesecakes, Oatmeal Peanut Butter Cookies, and this recipe are just a few of our favorites.

How To Make peanut butter cake

  • 1
    Preheat the oven to 350 degrees. Grease and flour a 15×10 inch jelly roll pan.
  • 2
    In a large bowl whisk together flour, sugar, baking soda, and salt.
  • 3
    Combine water and butter in a large saucepan and heat until the butter melts. Make sure the saucepan is large enough to mix a cake in. Whisk in the peanut butter until smooth. Remove from the heat and let cool for 10-15 minutes stirring several times.
  • 4
    Stir the dry mixture into the wet mixture just enough to get it started. Add the eggs, buttermilk, and vanilla. Stir just enough to combine. Pour into the prepared pan and bake for 24-28 minutes or until a toothpick inserted in the center comes out clean. Remove to a cooling rack and fully cool before preparing the frosting.
  • 5
    Cream butter and peanut butter until smooth and creamy. Add the powdered sugar in 1/2 cup increments alternating with 1 tablespoon of milk while continuing to beat on medium speed. Beat in the vanilla and salt. Continue beating for about 3-4 minutes or until the frosting is smooth and fluffy.
  • 6
    Frost the fully cooled cake.
