Ingredients and Preparation

Cake Ingredients

• 1¾ cups all-purpose flour
• ¾ cup black cocoa powder (sifted)
• 1 teaspoon baking soda
• 1 teaspoon fine sea salt
• 2 cups granulated sugar
• ½ cup neutral oil (vegetable or canola)
• 1 cup buttermilk (room temperature)
• 2 large eggs (room temperature)
• 1 teaspoon vanilla extract
• ⅔ cup hot brewed coffee or hot water

Frosting Ingredients

• 6 tablespoons unsalted butter
• ¾ teaspoon fine sea salt
• 1¾ cups heavy whipping cream
• 1½ cups granulated sugar
• 2 tablespoons light corn syrup (optional, for shine)
• ⅔ cup semi-sweet chocolate chips
• 1 cup Dutch-processed cocoa powder (sifted)
• ¾ cup black cocoa powder (sifted)
• 1 teaspoon vanilla extract

Preparation Notes

• Use room temperature ingredients for smoother mixing.
• Sift all cocoa powders to remove lumps and ensure even distribution.
• Use high-quality black cocoa powder for the signature color and flavor.
• Hot coffee intensifies the chocolate flavor, but hot water is a fine substitute if needed.

Step-by-Step Instructions

Step 1: Prepare the Cake Pans

• Preheat oven to 350°F (175°C).
• Grease and line two 8-inch round cake pans with parchment paper.
• Lightly dust pans with cocoa powder instead of flour for a cleaner, richer finish.

Step 2: Mix the Dry Ingredients

• In a medium bowl, sift and whisk together the following:
  • 1¾ cups all-purpose flour
  • ¾ cup black cocoa powder
  • 1 teaspoon baking soda
  • 1 teaspoon sea salt

Step 3: Combine the Wet Ingredients

• In a large bowl or stand mixer, whisk together until smooth:
  • 2 cups sugar
  • ½ cup neutral oil
  • 1 teaspoon vanilla extract
  • 2 large eggs
  • 1 cup buttermilk
• Mix for about 1 minute until well combined and creamy.

Step 4: Add the Hot Liquid

• Slowly pour ⅔ cup hot coffee (or water) into the wet mixture.
• Mix gently on low speed until fully incorporated.
• The batter will be thin, which is normal.

Step 5: Combine Wet and Dry

• Gradually add the dry ingredients to the wet batter in two to three parts.
• Mix just until no streaks of flour remain—do not overmix.
• Scrape down the sides and bottom of the bowl to ensure even blending.

Step 6: Bake the Cake Layers

• Divide batter evenly between the prepared pans.
• Bake for 32 to 36 minutes, or until a toothpick inserted comes out with a few moist crumbs.
• Remove pans and cool on a rack for 10 minutes.
• Invert cakes onto the rack, peel off parchment, and cool completely.

Step-by-Step: Make the Frosting

Step 1: Heat the Cream Mixture

• In a saucepan over medium heat, combine:
  • 6 tablespoons butter
  • 1¾ cups heavy cream
  • 1½ cups sugar
  • Optional: 2 tablespoons corn syrup
• Stir frequently until butter is melted and the mixture begins to bubble (not boil).

Step 2: Add Cocoa and Chocolate

• Remove pan from heat.
• Whisk in:
  • ⅔ cup semi-sweet chocolate chips
  • 1 cup Dutch-process cocoa
  • ¾ cup black cocoa
  • 1 teaspoon vanilla extract
• Continue whisking until the mixture is thick, glossy, and fully combined.

Step 3: Cool and Whip

• Let frosting cool at room temperature for about 2 hours.
  • For quicker cooling, refrigerate for 30–40 minutes.
• Once thickened but not hard, whip with a hand or stand mixer on high speed for 3–5 minutes until smooth and fluffy.

Step 4: Assemble and Frost

• Level cake layers if needed.
• Place one cake layer on a serving plate or cake stand.
• Spread a generous layer of frosting on top.
• Add the second layer, then cover the entire cake with remaining frosting.
• Use a spatula to create smooth sides or textured swirls as desired.

Beginner Tips and Notes

• Black cocoa powder is very dark and low in acidity. It gives the cake its signature color and Oreo-like taste.
• Don’t substitute black cocoa 1:1 with regular cocoa—it changes the flavor and moisture.
• Baking time can vary depending on pan depth and oven heat. Start checking at 30 minutes.
• If your frosting is too soft, refrigerate it for 10–15 minutes and whip again.
• If your frosting is too thick, let it sit at room temperature before mixing.
• Use a serrated knife to trim the tops of the cake layers for an even, professional look.
• For extra contrast, sprinkle the top with powdered sugar or garnish with chocolate shavings.
• Cake can be made a day ahead. Wrap layers tightly in plastic wrap and refrigerate.
