Step-by-Step Instructions
To begin, preheat your oven to 350°F (175°C) and prepare your baking sheet by greasing it lightly with cooking spray or butter. In a large mixing bowl, combine the flour, granulated sugar, cocoa powder, baking soda, baking powder, and salt. I love the way the cocoa powder adds a rich color to my mixture as I stir! Next, add the eggs, buttermilk, vegetable oil, and vanilla extract to the dry ingredients. Mix until smooth, and then carefully pour in the boiling water. This step makes the batter thin, but don’t worry—it’s supposed to be! (See the next page below to continue steps…)
