3/4 teaspoons baking powder
1 teaspoon kosher salt
1 cup buttermilk, at room temperature
1/2 cup vegetable oil
3 large eggs, at room temperature
1 teaspoon vanilla extract
1 cup hot water
Preheat oven 350 degrees. Spray three 8-inch or four 6-inch cake pans with nonstick spray. Line bottom of each pan with parchment paper, then spray the pans again. Set aside.
In the bowl of an electric mixer sift together the flour cocoa, baking soda, baking powder, and salt. Add sugar and mix with paddle attachment on low speed until combined.
In another bowl, combine the buttermilk, oil, eggs, water and vanilla.
