Equipment

Ingredients

  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 2 cups granulated sugar
  • 1 cup butter (2 sticks), softened I use salted butter
  • 1/4 cup unsweetened cocoa powder
  • 1 cup water
  • 1 teaspoon vanilla extract
  • 1/2 cup sour cream
  • 2 large eggs lightly beaten

Peanut Butter Frosting

Instructions

  • Preheat oven to 350 degrees and spray a 18x13-inch pan with baking spray with flour.
    Or you can butter and flour the pan.
  • Whisk together flour, baking soda, salt, and sugar in a large bowl. Set aside.
  • Add butter, cocoa powder, and water to a medium saucepan. Heat until mixture comes to a boil. Cool for a few minutes. Stir well and pour over flour mixture.
    Stir into flour mixture.
  • Add vanilla, sour cream, and eggs. Mix until evenly combined.
  • Transfer batter to prepared pan and bake for 20 to 25 minutes. Let cool.
  • To make frosting, use a hand-held or stand electric mixer to beat peanut butter and butter until creamy.
  • Add remaining ingredients and beat on high for 2 to 3 minutes.
  • Spread frosting on cake.

Notes

Unsalted butter can be used instead of salted butter. Just add a pinch more salt.
Let the chocolate mixture cool slightly. After bringing the butter, cocoa, and water to a boil, let it sit for a few minutes before combining it with the flour mixture. This helps prevent the eggs from cooking when they are added.
