Ingredients

Scale
  • 2 ½ cups (315g) all-purpose flour, spooned and leveled
  • 2 cups (400g) granulated sugar
  • ¾ cup (75g) natural unsweetened cocoa powder
  • 1 ½ teaspoons baking soda
  • 1 teaspoon baking powder
  • 1 teaspoon salt
  • 2 large eggs, room temperature
  • 1 cup (240ml) buttermilk or homemade (milk + vinegar)
  • ½ cup (120ml) vegetable oil
  • 2 teaspoons vanilla extract
  • 1 cup (240ml) hot water
  • 8 oz (225g) cream cheese, softened
  • ½ cup (115g) unsalted butter, softened
  • 3 cups (360g) powdered sugar, sifted
  • 1 cup (250g) creamy peanut butter
  • 1 teaspoon vanilla extract
  • 2 to 3 tablespoons heavy cream or whole milk
  • Optional: ½ cup chopped Reese’s peanut butter cups
  • Optional: pinch of sea salt flakes

Instructions

  1. Preheat oven to 350°F (175°C). Grease two 9-inch round cake pans and line bottoms with parchment paper.
  2. In a large bowl, sift together flour, sugar, cocoa powder, baking soda, baking powder, and salt. Whisk to combine.
  3. In a separate bowl, whisk eggs, buttermilk, vegetable oil, and vanilla extract until smooth.
  4. Gradually add wet ingredients to dry ingredients, stirring just until combined. Slowly pour in hot water and mix gently until smooth. Batter will be thin.
  5. Divide batter evenly between pans. Bake 30-35 minutes or until toothpick inserted comes out clean or with a few moist crumbs. Rotate pans halfway through baking.
  6. Cool cakes in pans for 10 minutes, then transfer to wire rack to cool completely.
  7. For frosting, beat cream cheese and butter until smooth and creamy. Add peanut butter and vanilla, mixing until combined.
  8. Gradually add powdered sugar, beating on low speed to avoid sugar dust. Add heavy cream or milk to reach spreadable consistency.
  9. Place one cake layer on serving plate. Spread one-third of frosting evenly on top. Add second layer and frost top and sides with remaining frosting.
  10. If using, fold chopped Reese’s cups into a small portion of frosting for topping or sprinkle on top. Add a pinch of sea salt flakes if desired.
  11. Refrigerate cake for at least 30 minutes before slicing to set frosting.

Notes

Measure flour correctly by spooning and leveling to avoid dense cake. Use hot water to bloom cocoa powder for richer chocolate flavor. Keep cream cheese and butter at room temperature for smooth frosting. Chill assembled cake before slicing for cleaner cuts. Frosting can be refrigerated briefly if too soft before spreading.
