Method
Preparation
- Preheat your oven to 350°F (175°C). Grease a 10×15 baking pan or spray it with cooking spray for easy release.
- In a large mixing bowl, whisk together 2 cups of flour, 2 cups of sugar, 1 teaspoon of baking soda, and 1/2 teaspoon of salt until evenly combined. Set aside.
- In a small saucepan, melt 1 cup of butter over medium-high heat. Stir in 1/2 cup of cocoa powder and 1 cup of black coffee or water, bringing the mixture to a boil. Remove from heat.
- In a separate bowl, combine 1/2 cup of buttermilk, 2 eggs, and 2 teaspoons of vanilla extract. Mix well to blend the ingredients and set aside.
- Pour the hot cocoa mixture into the flour mixture and stir until just combined. Then, add the buttermilk mixture, whisking until you have a smooth batter.
Baking
- Pour the batter into the prepared baking pan and bake for 20-22 minutes, or until a toothpick inserted in the center comes out clean. Allow the cake to cool slightly in the pan.
Icing Preparation
- For the icing, sift together 1 box of powdered sugar and 1/2 cup of cocoa powder into a bowl.
- In a small saucepan, combine 3/4 cup of butter, 1/2 cup of milk, and a dash of salt. Heat until it simmers, then stir in 1 teaspoon of vanilla extract.
- Pour this warm mixture into the bowl of sifted sugar and cocoa, stirring until the icing is smooth and creamy.
- Allow the icing to sit for 5 minutes, then pour it over the warm cake, spreading evenly. Let the cake rest for a few hours before serving to allow the icing to set.

Notes
For added flavor, you can replace black coffee with strong brewed coffee. Store any leftovers in an airtight container at room temperature for up to three days, or refrigerate for up to a week. This sheet cake can be frozen for up to three months. Consider adding nuts, such as pecans or walnuts, to the batter for extra crunch.
