Description

A dense, moist peanut butter cake with even more peanut butter love in the frosting.

Ingredients

  • FOR THE SHEET CAKE:
  • 2 cups Sugar
  • 2 cups All-purpose Flour
  • 2 whole Large Eggs
  • 1 teaspoon Baking Soda
  • 1 cup Sour Cream
  • ⅔ cups Creamy Peanut Butter
  • 1 cup Butter
  • 1 cup Water
  • FOR THE PEANUT BUTTER FROSTING:
  • ½ cups Butter
  • ⅔ cups Creamy Peanut Butter
  • 6 Tablespoons Milk
  • 2-½ cups Powdered Sugar
  • 1 teaspoon Vanilla

Preparation

Preheat oven to 400ºF.

For the cake: In a bowl combine the sugar and flour. In a separate bowl (I used my mixer bowl) mix eggs, baking soda, and sour cream well. Set aside. In a small saucepan combine peanut butter, butter, and water. Bring to a boil. Stir the boiled peanut butter mixture into the flour mixture, then add to the sour cream mixture. Pour into an ungreased 15×10 inch sheet/jellyroll type pan. Bake 20 minutes or until done. Cake is done when a toothpick inserted in the center of the cake comes out clean.

For the frosting: Combine the butter, peanut butter, and milk in a saucepan. Bring to a boil stirring constantly. Add the powdered sugar and mix well. Let the frosting cool for a few minutes, then add vanilla. The frosting will be thick; mix well. Pour over cake while both are still warm. Let cool, then serve.

I’ve made this recipe twice and it was delicious both times. Even if you don’t like peanut butter you will still love this cake. It’s moist and delicious. Excellent crumb! I chopped up a Hershey chocolate bar and sprinkled over the top. Everyone loved it!!!

Made this for a potluck and it was a huge hit. I was worried that having the peanut butter in the cake and the frosting would be overwhelming, but it was perfectly balanced. This one is going in the sheet cake arsenal!
