Ingredients You'll Need
- 2 cups all-purpose flour
- 2 cups granulated sugar
- 1 cup unsalted butter, softened
- 4 large eggs
- 1 cup buttermilk
- 3/4 cup cocoa powder
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 teaspoon vanilla extract
- 1 cup boiling water
For the Fudgy Chocolate Icing:
- 1/2 cup unsalted butter
- 3 tablespoons cocoa powder
- 6 tablespoons milk
- 3 cups powdered sugar
- 1 teaspoon vanilla extract
- Pinch of salt
Step-by-Step Instructions
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch sheet pan or line it with parchment paper for easy removal.
Step 2: Mix Dry Ingredients
In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking soda, and salt. This ensures even distribution of all the leavening agents and flavor components.
Step 3: Combine Wet Ingredients
Add the softened butter, eggs, buttermilk, and vanilla extract to the dry ingredients. Mix on medium speed until just combined – be careful not to overmix, which can lead to a tough cake.
Step 4: Add Boiling Water
Slowly pour in the boiling water while mixing on low speed. The batter will be thin – this is normal and contributes to the cake's incredible moisture.
Step 5: Bake to Perfection
Pour the batter into your prepared sheet 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.
Step 6: Make the Fudgy Icing
While the cake cools slightly, prepare the icing. Melt butter in a saucepan over medium heat. Whisk in cocoa powder and milk until smooth. Remove from heat and stir in powdered sugar, vanilla, and salt until you achieve a pourable consistency.
Step 7: Ice and Serve
Pour the warm icing over the slightly warm cake, spreading it evenly with a spatula. Allow the icing to set before cutting into generous squares and serving.
Expert Tips for Perfect Results
For Extra Moist Cake: Don't skip the boiling water step – it helps bloom the cocoa powder and creates an exceptionally moist texture.
Room Temperature Ingredients: Ensure your eggs and buttermilk are at room temperature for even mixing and better rise.
Don't Overmix: Mix just until ingredients are combined to avoid developing too much gluten, which can make the cake dense.
Cooling Matters: The cake should be slightly warm (not hot) when you apply the icing so it sets perfectly without melting away.
Storage Tips: Store covered at room temperature for up to 3 days. This cake actually gets more moist and flavorful the next day!
