Instructions
Preheat the oven to 350°F (175°C). Prepare two 9-inch round cake pans by greasing and lightly flouring them, then lining the bottoms with rounds of parchment paper.
In a large bowl, combine the flour, sugar, cocoa powder, baking powder, baking soda, and salt. Whisk thoroughly to ensure even distribution of all dry components.
Add the eggs, buttermilk, oil, and vanilla to the bowl. Use a hand mixer or stand mixer to beat the mixture until a smooth and consistent batter forms.
Gradually pour in the boiling water while mixing at low speed. The batter will be thin; this ensures a tender, moist crumb.
Divide the batter evenly between the prepared pans. Place on the center rack of the oven and bake for 30 to 35 minutes, or until a toothpick inserted into the center of each cake comes out clean.
Allow the cakes to cool in the pans for 10 minutes. Then, carefully invert onto wire racks and let them cool completely before applying frosting, if desired.
This cake remains moist for days and pairs exceptionally well with fruit fillings or espresso-flavored frostings. Store any leftovers in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
