Ingredients
  • 250g all-purpose flour, sifted
  • 75g unsweetened cocoa powder
  • 400g granulated white sugar
  • 100g light brown sugar
  • 12g baking powder
  • 6g baking soda
  • 6g fine sea salt
  • 2 large large eggs, room temperature
  • 240ml buttermilk, room temperature
  • 240ml hot strong black coffee
  • 120ml neutral vegetable oil
  • 10ml pure vanilla extract
  • 115g unsalted butter, melted and cooled
Instructions
  1. Preheat your oven to 175°C (350°F). Grease two 23cm (9-inch) round cake pans with butter and dust with cocoa powder, tapping out excess. Line the bottoms with parchment paper for easy removal.

  2. In a large mixing bowl, whisk together 250g all-purpose flour, 75g unsweetened cocoa powder, 400g granulated white sugar, 100g light brown sugar, 12g baking powder, 6g baking soda, and 6g fine sea salt until well combined and no lumps remain.

  3. In a separate bowl, beat 2 large large eggs lightly, then whisk in 240ml buttermilk, 120ml neutral vegetable oil, 10ml pure vanilla extract, and 115g unsalted butter until smooth and well combined.

  4. Pour the wet ingredients into the dry ingredients and mix with a wooden spoon or electric mixer on medium speed until just combined. Don't overmix - a few small lumps are fine.

  5. Gradually stir in 240ml hot strong black coffee until the batter is smooth. The batter will be quite thin - this is normal and creates the incredibly moist texture.

  6. Divide the batter evenly between the prepared pans, using a kitchen scale for accuracy if available. Each pan should have about 600g of batter.

  7. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs attached. The tops should spring back lightly when touched.

  8. Cool in pans for 10 minutes, then turn out onto wire racks. Remove parchment paper and cool completely before frosting, about 1 hour.

Tips

Coffee Secret: The hot coffee intensifies the chocolate flavor without making the cake taste like coffee - it's the secret to professional-level chocolate cakes.

Room Temperature Ingredients: Ensure eggs and buttermilk are at room temperature for the smoothest batter and even mixing. Take them out 1-2 hours before baking.

Measuring Cocoa: Sift cocoa powder before measuring to avoid lumps and ensure accurate measurement. Dutch-processed cocoa will give a deeper color and milder flavor.

Perfect Doneness: The cake is done when it just begins to pull away from the sides of the pan and a toothpick has moist crumbs (not wet batter) clinging to it.

Storage: Wrap unfrosted layers tightly in plastic wrap and store at room temperature for up to 3 days, or freeze for up to 3 months.

Frosting Pairings: This cake pairs beautifully with classic chocolate buttercream, cream cheese frosting, or even simple whipped cream with fresh berries.

Make-Ahead: Cake layers can be baked up to 2 days ahead and stored covered at room temperature. They actually improve in flavor overnight.

Altitude Adjustments: If baking above 1000m (3000ft), reduce baking powder by 1/4 and increase liquid by 2-4 tablespoons.
