Ingredients
For the Cake:
- 2 cups all-purpose flour
- 2 cups granulated sugar
- 3/4 cup unsweetened cocoa powder
- 2 teaspoons baking soda
- 1 teaspoon baking powder
- 1 teaspoon salt
- 1 cup buttermilk
- 1 cup vegetable oil
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup hot water
For the Fudgy Frosting:
- 1/2 cup butter
- 1/3 cup unsweetened cocoa powder
- 1/3 cup milk
- 4 cups powdered sugar
- 1 teaspoon vanilla extract
- Pinch of salt
Step-by-Step Instructions
1. Prepare the Batter
Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan and set aside. In a large bowl, whisk together flour, sugar, cocoa powder, baking soda, baking powder, and salt until well combined.
2. Mix Wet Ingredients
In a separate bowl, combine buttermilk, vegetable oil, eggs, and vanilla extract. Mix until smooth. Pour the wet ingredients into the dry ingredients and stir until just combined. Gradually add the hot water while mixing – the batter will be thin, which is perfect for a moist cake.
3. Bake to Perfection
Pour the batter into your prepared pan and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. The cake should spring back when lightly touched. Let the cake cool completely in the pan before frosting.
4. Make the Fudgy Frosting
While the cake cools, prepare the frosting. Melt butter in a medium saucepan over medium heat. Whisk in cocoa powder until smooth. Stir in milk and bring to a gentle boil. Remove from heat and immediately whisk in powdered sugar, vanilla extract, and salt until smooth and glossy.

5. Frost and Serve
Pour the warm frosting over the completely cooled cake. Use an offset spatula to spread it evenly across the surface. The frosting will set as it cools, creating that signature fudgy texture.
Expert Tips for Perfect Results
Don’t Overmix: When combining wet and dry ingredients, mix just until combined. Overmixing can lead to a tough cake texture.
Hot Water Secret: The hot water helps “bloom” the cocoa powder, intensifying the chocolate flavor and creating a moist crumb.
Cool Completely: Wait until the cake is completely cool before frosting. Warm cake will melt the frosting and create a messy appearance.
Storage: Store covered at room temperature for up to 3 days. For longer storage, refrigerate for up to a week.
