Ingredients

Scale

Dry Ingredients

  • 2 cups all-purpose flour
  • 2/3 cup cocoa powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt

Wet Ingredients

  • 1/2 cup unsalted butter
  • 1 cup boiling water
  • 2 cups granulated sugar
  • 1 cup buttermilk
  • 1/2 cup vegetable oil
  • 2 large eggs
  • 1 teaspoon vanilla extract

Frosting Ingredients

  • 1/2 cup unsalted butter
  • 1/4 cup cocoa powder
  • 1/3 cup evaporated milk
  • 3 1/2 cups powdered sugar

Instructions

  1. Prepare Your Pan and Oven: Preheat your oven to 350°F (175°C) and lightly grease a 9×13 inch sheet cake pan with butter or non-stick spray to ensure easy removal after baking.
  2. Mix Dry Ingredients: In a large bowl, whisk together all-purpose flour, cocoa powder, baking soda, and salt until evenly combined to distribute the chocolate and leavening agents consistently.
  3. Combine Wet Ingredients: In a medium saucepan, melt the unsalted butter over medium heat. Stir in the boiling water to dissolve the cocoa powder and intensify the chocolate flavor. Remove from heat, then add granulated sugar, buttermilk, vegetable oil, eggs, and vanilla extract. Stir until smooth and well blended.
  4. Blend Wet and Dry Ingredients: Gradually add the wet mixture to the dry ingredients, stirring gently until the batter is smooth but not overmixed to maintain a tender, light texture.
  5. Bake the Cake: Pour the batter evenly into the prepared pan and bake for 30-35 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs.
  6. Prepare the Frosting: While the cake bakes, heat butter, cocoa powder, evaporated milk, and powdered sugar in a saucepan over medium heat, stirring continuously until smooth and slightly thickened to create a creamy chocolate frosting.
  7. Frost and Cool: Once the cake is out of the oven, immediately spread the warm frosting evenly over the top so it melts slightly into the cake. Let the cake cool completely before slicing to ensure clean cuts and set frosting.

Notes

  • Use room temperature eggs for better incorporation into the batter.
  • Don’t skip buttermilk; it adds tenderness and a slight tanginess to balance the sweetness.
  • Boiling water helps activate and enhance the cocoa powder’s deep chocolate flavor.
  • Spread frosting while warm for a gooey, smooth finish.
  • Allow the cake to cool completely before slicing to prevent frosting from melting and to achieve neat slices.
  • Use fresh cocoa powder for the richest chocolate flavor.
