Instructions
1. Prepare the Chocolate Cake:
Preheat the oven to 350°F (175°C). Grease and line three 8-inch round cake pans with parchment paper.
In a large mixing bowl, whisk together flour, sugar, cocoa powder, baking soda, baking powder, and salt.
Add buttermilk, oil, eggs, and vanilla extract. Beat until smooth.
Gradually add the boiling water, mixing until the batter is thin and smooth.
Divide the batter evenly among the prepared pans. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
Cool the cakes in the pans for 10 minutes, then transfer them to a wire rack to cool completely.
