Instructions
- Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, then line bottoms with parchment paper circles.
- In a large mixing bowl, whisk together flour, sugar, cocoa powder, baking soda, baking powder, and salt until well combined and lump-free.
- In a separate bowl, whisk together buttermilk, vegetable oil, eggs, and vanilla extract until smooth.
- Gradually add wet ingredients to dry ingredients, mixing on medium speed until just combined.
- Slowly stir in boiling water until combined (batter will be thin).
- Divide batter evenly between prepared pans and bake for 30-35 minutes until toothpick inserted comes out clean.
- Let cakes cool in pans for 10 minutes, then turn out onto wire racks to cool completely.
- Beat softened butter until creamy, then gradually add powdered sugar and cocoa powder alternating with milk. Add vanilla and salt, beat until light and fluffy.
- Place one cake layer on serving plate, spread with frosting, top with second layer, and frost top and sides generously.
Notes
Use room temperature ingredients for smoother incorporation. Don't overmix ingredients. Use high-quality cocoa powder. Test for doneness at 30 minutes. Store covered at room temperature for up to 3 days - flavors improve after a day.
