For the Chocolate Cake:

  • 2 cups granulated sugar
  • 1¾ cups all-purpose flour
  • 1 cup melted butter
  • 1 cup buttermilk
  • ½ cup cocoa powder
  • 4 eggs
  • 1 tablespoon baking powder
  • 2 teaspoons vanilla extract
  • ½ teaspoon kosher salt
  • 1 (3-ounce) dark chocolate baking bar, melted
  • ½ cup boiling hot water or coffee

For the Peanut Butter Fluff Frosting:

  • 1 (8-ounce) package cream cheese, softened
  • 1 cup of your favorite peanut butter
  • 4 tablespoons butter, softened
  • 3-4 cups confectioners’ sugar
  • 1 teaspoon vanilla extract
  • 1 pinch salt
  • ½ cup roasted salted peanuts, for topping


  1. Preparation: Preheat your oven to 350°F. Butter, flour, and line a 9-by-13-inch baking pan with parchment paper to ensure easy removal of the cake.
  2. Cake Batter: In a large mixing bowl, combine sugar, flour, melted butter, buttermilk, cocoa powder, eggs, baking powder, vanilla, and salt. Gently mix until the ingredients come together.
  3. Chocolate Elixir: Once the batter is well-mixed, introduce the melted dark chocolate and hot water or coffee. Blend until smooth, ensuring to scrape down the sides of the bowl to incorporate all the heavenly flavors.
  4. Baking Bliss: Pour the luscious batter into the prepared pan. Bake for approximately 28 to 32 minutes, keeping a watchful eye to prevent overbaking. The cake is ready when a toothpick inserted into the center comes out clean.
  5. Peanut Butter Fluff Frosting: In another bowl, whip together softened cream cheese, peanut butter, and butter until velvety smooth. Scrape down the sides of the bowl, then add confectioners’ sugar, vanilla, and a pinch of salt. Mix thoroughly until you achieve a delectable, fluffy frosting.
  6. Assembly: Once the cake has cooled to perfection, generously dollop the peanut butter fluff frosting onto the cake, spreading it out in delightful swirls. Top it off with roasted salted peanuts for a crunchy, nutty finish.
