Ingredients

For the Cake:

2 cups all-purpose flour
1 ¾ cups granulated sugar
¾ cup unsweetened cocoa powder
2 teaspoons baking soda
1 teaspoon baking powder
1 teaspoon salt
2 large eggs
1 cup buttermilk
½ cup vegetable oil
2 teaspoons vanilla extract
1 cup boiling water

For the Fudgy Icing:

½ cup unsalted butter
2 tablespoons unsweetened cocoa powder
¼ cup milk
3 cups powdered sugar
1 teaspoon vanilla extract
Pinch of salt

Step-by-Step Instructions

Step 1: Prepare the Cake Batter

Preheat your oven to 350°F (175°C). Grease and line a 9×13-inch baking pan with parchment paper. In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt until well combined.

Step 2: Combine Wet Ingredients

In a separate bowl, beat the eggs, then add the buttermilk, vegetable oil, and vanilla extract. Mix until smooth. Pour the wet ingredients into the dry ingredients and stir until just combined. Be careful not to overmix.

Step 3: Add Boiling Water

Gradually add the boiling water to the batter, stirring constantly. The batter will be thin – this is normal and will result in a moist cake. Pour the batter into your prepared pan and smooth the top with a spatula.

Step 4: Bake

Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool completely in the pan before icing.

Step 5: Make the Fudgy Icing

While the cake cools, prepare the icing. In a medium saucepan, melt the butter over medium heat. Stir in the cocoa powder and milk until smooth. Remove from heat and whisk in the powdered sugar, vanilla extract, and salt until the icing is smooth and glossy.

Step 6: Ice and Serve

Pour the warm icing over the cooled cake and spread evenly with a spatula. Allow the icing to set for about 10 minutes before slicing into squares. Serve at room temperature.

Expert Tips for Perfect Results

Room Temperature Ingredients: Ensure your eggs and buttermilk are at room temperature for the best texture. This helps create a light, fluffy crumb.

Don’t Overmix: Once you add the wet ingredients to the dry, mix just until combined. Overmixing can lead to a tough cake.

Test for Doneness: Start checking the cake at 30 minutes. It’s done when the edges pull away from the pan and the center springs back when lightly touched.

Cooling is Crucial: Make sure the cake is completely cool before adding the icing, or it will melt and soak into the cake.

Customization Ideas: Add chocolate chips, chopped nuts, or sprinkle with festive toppings for special occasions.
