Method
 

Preparation
  1. Preheat your oven to 350°F (175°C) and grease your cake pans.
  2. In a mixing bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt.
  3. Add the eggs, buttermilk, vegetable oil, and vanilla extract. Stir gently until combined.
  4. Pour in the hot water (or coffee) and mix until the batter is silky smooth.
  5. Pour the batter into prepared pans and bake for 30-35 minutes, until a toothpick comes out clean.
Icing
  1. While the cake cools, melt the butter and mix in cocoa powder.
  2. Stir in the buttermilk, vanilla, and half of the powdered sugar until smooth.
  3. Add the remaining powdered sugar to adjust to your desired consistency.
  4. If desired, fold in the chopped nuts and spread icing over the cooled cake.

Notes

For best results, use room temperature ingredients and allow the cake to cool completely before icing. For serving, pair with vanilla ice cream or coffee.
