Ingredients
  

For the Chocolate Cake

  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • 3/4 cup unsweetened cocoa powder
  • 2 teaspoons baking powder
  • 1 1/2 teaspoons baking soda
  • 1 teaspoon salt
  • 1 cup buttermilk (or 1 cup milk + 1 tbsp vinegar)
  • 1/2 cup vegetable oil
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 1 cup hot coffee Brings out the chocolate flavor, but you won’t taste the coffee!

For the Chocolate Ganache Frosting

  • 1 1/2 cups heavy cream
  • 2 cups semi-sweet chocolate chips
  • 2 tablespoons unsalted butter

For the Extra Fudgy Chocolate Sauce (Optional but Recommended!)

  • 1/2 cup unsweetened cocoa powder
  • 3/4 cup granulated sugar
  • 1/2 cup heavy cream
  • 1/4 cup unsalted butter
  • 1 teaspoon vanilla extract

Instructions
 

Preparation

  • Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
  • In a large mixing bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt.
  • Add buttermilk, oil, eggs, and vanilla extract. Beat on medium speed until smooth.
  • Stir in the hot coffee (the batter will be thin, but that’s normal—it makes the cake extra moist!).
  • Divide the batter evenly between the prepared cake pans.
  • Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
  • Let cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.

Make the Chocolate Ganache Frosting

  • Heat heavy cream in a saucepan over medium heat until it just starts to simmer (don’t let it boil!).
  • Remove from heat and pour over chocolate chips and butter in a bowl.
  • Let sit for 2–3 minutes, then stir until smooth and glossy.
  • Let it cool slightly until it thickens to a spreadable consistency.

Make the Extra Fudgy Chocolate Sauce (Optional)

  • In a saucepan, whisk together cocoa powder, sugar, heavy cream, and butter over medium heat.
  • Bring to a gentle simmer, stirring continuously for 3–5 minutes until thickened.
  • Remove from heat and stir in vanilla extract.

Assemble the Cake

  • Place one cake layer on a serving plate. Spread a generous amount of ganache frosting on top.
  • Add the second cake layer, then coat the entire cake with the remaining ganache.
  • If using the extra fudgy chocolate sauce, pour it over the cake for an ultra-gooey finish.
  • Let the cake set for 10–15 minutes, then serve.

Notes

For variations, consider adding chocolate chips to the batter, layers of peanut butter frosting, or a salted caramel drizzle. Store in the fridge for up to 5 days or freeze for up to 3 months.
