Ingredients
For the Cake
- 2½ cups all-purpose flour
- 2 cups granulated sugar
- ¾ cup unsweetened cocoa powder
- 2 teaspoons baking soda
- 1 teaspoon baking powder
- ½ teaspoon salt
- 3 large eggs
- 1¼ cups milk
- ¾ cup vegetable oil
- 2 teaspoons vanilla extract
- 1¼ cups hot coffee or hot water
For the Chocolate Frosting
- ½ cup unsalted butter
- 6 tablespoons milk
- 4 tablespoons unsweetened cocoa powder
- 3¾ cups powdered sugar
- 1 teaspoon vanilla extract
- ¼ teaspoon salt
Instructions
- Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking pan.
- In a large bowl, whisk together 2½ cups of flour, 2 cups of sugar, ¾ cup of cocoa powder, 2 teaspoons of baking soda, 1 teaspoon of baking powder, and ½ teaspoon of salt.
- Add 3 eggs, 1¼ cups of milk, ¾ cup of oil, and 2 teaspoons of vanilla extract. Whisk until smooth.
- Slowly pour in 1¼ cups of hot coffee, whisking constantly. The batter will be very thin, that’s exactly what you want.
- Pour the batter into the prepared pan. Bake for 35 to 40 minutes, until a toothpick inserted in the center comes out clean.
- While the cake bakes, add ½ cup of butter, 6 tablespoons of milk, and 4 tablespoons of cocoa powder to a saucepan over medium heat. Stir until the butter is melted and the mixture is smooth. Do not let it boil.
- Remove from heat and whisk in 3¾ cups of powdered sugar, 1 teaspoon of vanilla, and ¼ teaspoon of salt until smooth.
- Pour the warm frosting over the warm cake and spread evenly. Let it set for about 15 minutes before slicing.
Notes
- The batter will be very thin once the hot coffee is added. That’s normal and important for the final texture.
- Coffee deepens the chocolate flavor but does not make the cake taste like coffee. Hot water works if needed.
- Frost the cake while it’s still warm so the frosting spreads easily and sinks slightly into the top.
- Store covered at room temperature for a day or two, or refrigerate for longer storage.
