Ingredients

Cake Batter

  • 4 ounces semi-sweet chocolate, chopped
  • 6 tablespoons unsalted butter, cut into tablespoon-sized pieces
  • 1 1/2 cups water
  • 1 cup granulated sugar
  • 1 cup packed light brown sugar
  • 1/4 cup unsweetened cocoa powder
  • 2/3 cup sour cream
  • 1 teaspoon vanilla extract
  • 2 large eggs, lightly beaten
  • 2 cups all-purpose flour
  • 2 teaspoons baking powder
  • 2 teaspoons baking soda
  • 1 teaspoon kosher salt

Peanut Butter Frosting

  • 1 cup unsalted butter, softened
  • 8 ounces cream cheese, softened
  • 1 1/2 cups peanut butter
  • 3 cups powdered sugar
  • 1 tablespoon milk, optional

Instructions

  • Preheat oven to 350 degrees F.
    Line a 9x13-inch baking pan with parchment paper. Spray with baking spray with flour.
  • Place chocolate and butter in a large bowl.
  • Combine water, granulated sugar, and brown sugar in a medium saucepan. Place over medium-high heat. Bring to a boil whisking occasionally.
    Remove from heat and whisk in cocoa powder.
  • Pour hot sugar mixture into bowl with chocolate and butter. Let sit 2 minutes.
    Stir until chocolate and butter is melted.
  • Stir in the sour cream and vanilla.
  • Whisk in the eggs. Make sure mixture is not too hot before you add the eggs so they don't curdle.
  • In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
  • Whisk flour mixture into chocolate mixture, adding it in three batches. Whisk just until combined.
  • Pour batter into prepared pan. Bake for 30 to 35 minutes or until it feels firm when you press down in the center. Let cool in pan.
  • To make frosting, beat butter and cream cheese with an electric mixer until smooth.
  • Add peanut butter and beat until blended.
  • Beat in powdered sugar one cup at a time. If frosting is too thick, add the milk.
    Beat at medium speed for 2 minutes. Spread frosting on cake.
