Ingredients

Scale
  • 2 cups all-purpose flour (250g)
  • 2 cups granulated sugar (400g)
  • 1/2 cup unsweetened cocoa powder (50g)
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 1/2 cup unsalted butter (115g), melted
  • 1 cup buttermilk (240ml), room temperature
  • 2 large eggs, room temperature
  • 1 tsp vanilla extract
  • For the Rich Fudge Frosting:
  • 1/2 cup unsalted butter (115g), softened
  • 1/3 cup cocoa powder (33g)
  • 1/4 cup milk (60ml), whole milk preferred
  • 3 1/2 cups powdered sugar (440g), sifted
  • 1 tsp vanilla extract
  • Pinch of salt

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 13×9-inch baking pan lightly with butter or non-stick spray.
  2. In a large bowl, whisk together flour, sugar, cocoa powder, baking soda, and salt until evenly combined.
  3. In a medium saucepan over medium heat, melt the butter. Remove from heat and stir in the buttermilk until combined.
  4. Quickly whisk the melted butter and buttermilk mixture into the dry ingredients. Add eggs and vanilla extract, stirring until just combined. The batter will be thin.
  5. Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 25-30 minutes, checking doneness with a toothpick that should come out with a few moist crumbs.
  6. While the cake bakes, prepare the fudge frosting: melt butter in a saucepan over low heat. Stir in cocoa powder and milk, bring to a gentle boil, then remove from heat.
  7. Whisk in powdered sugar, vanilla extract, and salt until smooth and spreadable. Adjust consistency with milk or powdered sugar as needed.
  8. Spread the warm fudge frosting evenly over the hot cake so it soaks in.
  9. Let the cake cool for at least 30 minutes to set the frosting before slicing and serving.

Notes

Do not overmix the batter to keep the cake tender and moist. Use room temperature eggs and buttermilk for smooth blending. Spread frosting while the cake is still warm for best soak-in effect. Adjust frosting consistency with milk or powdered sugar as needed. Frosting can be made ahead and warmed gently before spreading. For gluten-free, substitute flour with a 1-to-1 gluten-free blend. For dairy-free, use dairy-free margarine or coconut oil and plant-based milk with vinegar as buttermilk substitute.
