Ingredients

Scale

For the Cake

  • 1 3/4 cups all-purpose flour
  • 1 3/4 cups granulated sugar
  • 3/4 cup unsweetened cocoa powder
  • 1 1/2 teaspoons baking powder
  • 1 1/2 teaspoons baking soda
  • 1 teaspoon salt
  • 2 large eggs
  • 1 cup whole milk
  • 1/2 cup vegetable oil
  • 2 teaspoons vanilla extract
  • 1 cup boiling water

For the Ganache

  • 8 ounces dark chocolate, chopped (70% cocoa or higher)
  • 1 cup heavy cream
  • 1 tablespoon unsalted butter (optional, for shine)

Instructions

  1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans to prevent sticking and ensure even baking.
  2. Prepare the Chocolate Cake Batter: In a large mixing bowl, sift together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. Then add the eggs, milk, vegetable oil, and vanilla extract to the dry ingredients. Beat the mixture on medium speed for about 2 minutes until well combined. Carefully stir in the boiling water; the batter will be thin but this is normal. Mix until smooth.
  3. Bake the Cake: Divide the batter evenly between the prepared cake pans. Place them in the oven and bake for 30-35 minutes or until a toothpick inserted into the center comes out clean. Remove from oven and let cakes cool in pans for 10 minutes before transferring them to wire racks to cool completely.
  4. Prepare the Chocolate Ganache: Heat the heavy cream in a saucepan over medium heat until it just begins to simmer; avoid boiling. Place the chopped dark chocolate in a heatproof bowl and pour the hot cream over it. Let it sit for 2-3 minutes to melt the chocolate. Stir gently until the mixture is smooth and glossy. Optionally, stir in the butter for extra shine.
  5. Assemble the Cake: Place one cake layer on a serving plate and spread a layer of ganache evenly on top. Add the second layer of cake and pour the remaining ganache over the top, letting it drip down the sides. Allow the ganache to set for about 30 minutes to firm up before slicing.
  6. Serve: Slice the cake and serve. Enjoy this luscious chocolate ganache cake, perfect for any chocolate dessert craving.

Notes

  • Use high-quality dark chocolate with at least 70% cocoa for the best ganache flavor and texture.
  • Allow the cake layers to cool completely before adding the ganache to prevent melting or sliding.
  • For a shiny ganache finish, adding butter is optional but recommended.
  • You can store leftover cake in an airtight container in the refrigerator for up to 3 days.
  • Bring the cake to room temperature before serving for the best taste and texture.
