Ingredients
- 1 cup butter
- 1 cup water
- 8 tablespoons unsweetened cocoa powder, divided
- 1/2 cup plus 1/3 cup buttermilk, divided
- 1 teaspoon baking soda
- 2 large eggs, beaten
- 2 teaspoons vanilla extract, divided
- 2 cups all-purpose flour
- 2 cups white sugar
- 1 teaspoon ground cinnamon
- 1/2 teaspoon salt
- 1 pound confectioners’ sugar
- 1 cup chopped pecans
Instructions
- Preheat oven to 350 degrees F (175 degrees C) and grease and flour a 9×13 inch baking pan.
- In a saucepan over medium heat, melt 1 cup of butter and stir in water and 4 tablespoons of cocoa powder; bring to a boil then remove from heat to cool slightly.
- In a medium bowl, combine 1/2 cup buttermilk with baking soda, then stir in the beaten eggs and 1 teaspoon vanilla extract before whisking in the cooled cocoa mixture.
- In a large bowl, sift together flour, white sugar, cinnamon, and salt; create a well and stir in the chocolate mixture by hand until blended.
- Pour batter into the prepared pan and bake for 30 minutes, or until a toothpick inserted in the center comes out clean.
- While the cake is in its final minutes of baking, melt 1/2 cup butter with 4 tablespoons cocoa powder and 1/3 cup buttermilk in a saucepan; remove from heat and whisk in confectioners’ sugar, 1 teaspoon vanilla, and chopped pecans.
- Pour the warm icing directly over the hot cake immediately after removing it from the oven and spread gently to the edges.
Notes
To ensure a perfectly smooth icing, always sift your confectioners’ sugar before adding it to the saucepan to prevent stubborn lumps. For a deeper chocolate flavor, you can replace the water in the cake batter with hot brewed coffee without changing the overall texture.
