Instructions
Ingredients
- Preheat oven to 350°F (175°C). Grease a 10×15-inch baking sheet and set aside.In a large mixing bowl, whisk together flour, sugar, baking soda, baking powder, salt, and cocoa powder until evenly combined.In a separate bowl, mix vegetable oil, buttermilk, eggs, and vanilla until smooth.Add the wet ingredients to the dry ingredients and beat until fully combined, about 2 minutes.Carefully stir in the boiling water until the batter is smooth and thin.Pour batter evenly into the prepared pan.Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.Cool completely before frosting with chocolate ganache or desired frosting.
Notes
- This cake pairs especially well with chocolate ganache frosting.The batter will be thin after adding boiling water—this is normal and helps create a moist cake.Allow the cake to cool fully before frosting for the cleanest finish.
