Ingredients

Scale
  • 1 cup boiling water (240 ml)
  • 3/4 cup unsweetened cocoa powder (65 g)
  • 2 cups all-purpose flour (250 g) or gluten-free blend for GF option
  • 2 cups granulated sugar (400 g)
  • 1 tsp baking soda
  • 1/2 tsp baking powder
  • 1/2 tsp salt
  • 1 cup buttermilk, room temperature (240 ml) or 1 cup milk + 1 tbsp lemon juice, let sit 5 mins
  • 2 large eggs, room temperature
  • 1/2 cup unsalted butter, melted (115 g)
  • 1 tsp vanilla extract
  • For the Warm Fudge Frosting:
  • 1/2 cup unsalted butter (115 g)
  • 1/4 cup milk (60 ml), whole milk preferred
  • 1/4 cup unsweetened cocoa powder (22 g)
  • 3 1/2 cups powdered sugar, sifted (440 g)
  • 1 tsp vanilla extract
  • A pinch of salt

Instructions

  1. Preheat oven to 350°F (175°C) and grease a 9×13 inch baking pan.
  2. In a medium saucepan, bring 1 cup boiling water to a boil. Remove from heat and whisk in 3/4 cup cocoa powder until smooth.
  3. In a large mixing bowl, whisk together 2 cups flour, 2 cups sugar, baking soda, baking powder, and salt.
  4. Add the cocoa-water mixture to the dry ingredients and stir gently until combined.
  5. Mix in buttermilk, eggs, melted butter, and vanilla extract until just combined; do not overmix.
  6. Pour batter evenly into the prepared pan and smooth the top.
  7. Bake for 25 to 30 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
  8. While the cake bakes, prepare the warm fudge frosting: melt butter with milk and cocoa powder in a saucepan over medium heat, whisking constantly.
  9. Bring to a gentle boil for 1 minute, then remove from heat.
  10. Gradually whisk in powdered sugar, vanilla extract, and salt until thickened. Add milk if too thick.
  11. Pour the warm fudge frosting evenly over the hot cake as soon as it comes out of the oven and spread if needed.
  12. Let the cake cool for at least 30 minutes before slicing to allow frosting to set slightly.

Notes

Use room temperature eggs and buttermilk for best texture. Stir frosting constantly while heating to prevent burning. Pour frosting immediately after baking for best melting effect. Overmixing batter can make cake tough. For gluten-free, use a 1:1 gluten-free flour blend. For dairy-free, substitute milk and butter with plant-based alternatives.
