Ingredients
This recipe makes 12 generous servings.
For the Cake
- 2 cups (250g) all-purpose flour
- 2 cups (400g) granulated sugar
- ¾ cup (65g) unsweetened cocoa powder (Dutch-processed for darker color)
- 2 teaspoons baking soda
- 1 teaspoon baking powder
- 1 teaspoon salt
- 1 cup (240ml) buttermilk (or 1 cup milk + 1 tbsp white vinegar/lemon juice, let sit 5 mins)
- ½ cup (120ml) vegetable oil
- 2 large eggs
- 1 teaspoon pure vanilla extract
- 1 cup (240ml) hot strong brewed coffee (or hot water)
For the Ganache
- 12 ounces (340g) good quality dark chocolate, finely chopped (60-70% cacao)
- 1 cup (240ml) heavy cream
- 2 tablespoons (28g) unsalted butter, cut into small pieces
- 1 teaspoon pure vanilla extract (optional, but recommended)
Step-by-Step Instructions
-
Step 1: Prepare Your Pans
Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. You can also line the bottoms with parchment paper for easy removal.
Small tip: Use a light dusting of cocoa powder instead of flour for greasing dark cakes to prevent white marks.
-
Step 2: Combine Dry Ingredients
In a large mixing bowl, whisk together the flour, granulated sugar, cocoa powder, baking soda, baking powder, and salt. Make sure there are no lumps and everything is well combined.
-
Step 3: Mix Wet Ingredients (Except Hot Liquid)
In a separate medium bowl, whisk together the buttermilk, vegetable oil, eggs, and vanilla extract. This ensures everything is evenly distributed before adding to the dry mix.
-
Step 4: Combine Wet and Dry
Pour the wet ingredients into the dry ingredients. Mix on low speed with an electric mixer, or by hand with a whisk, until just combined. Do not overmix the batter.
-
Step 5: Add the Hot Coffee/Water
Carefully pour the hot coffee (or hot water) into the batter. Mix on low speed until the batter is smooth and a bit thin. This hot liquid helps bloom the cocoa and makes the cake extra moist.
Small tip: The batter will be quite thin; this is normal for a super moist chocolate cake.
-
Step 6: Bake the Cakes
Divide the batter evenly between your prepared cake pans. Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean. The tops will spring back when lightly touched.
-
Step 7: Cool the Cakes
Let the cakes cool in their pans for about 10-15 minutes. Then, invert them onto a wire rack to cool completely. Cooling completely is crucial before frosting.
Small tip: Warm cakes will melt your ganache, so patience here is key for a beautiful finish.
-
Step 8: Prepare for Ganache
While the cakes cool, finely chop your dark chocolate and place it in a medium heatproof bowl. The finer the chop, the faster and more smoothly it will melt.
-
Step 9: Heat the Cream
In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer around the edges. Do not let it come to a rolling boil.
-
Step 10: Pour and Rest
Pour the hot cream over the chopped chocolate in the bowl. Let it sit undisturbed for 5 minutes. This allows the hot cream to melt the chocolate gently.
-
Step 11: Whisk the Ganache
After 5 minutes, gently whisk the chocolate and cream together, starting from the center and working your way out, until smooth and glossy. Add the butter and vanilla extract (if using) and whisk until fully incorporated and shiny.
Small tip: If the ganache seems a little thick, you can gently warm it over a double boiler or in the microwave for a few seconds, stirring often.
-
Step 12: Assemble and Frost
Once the cakes are completely cool, place one layer on your serving plate. Pour about half of the ganache over the first layer and spread it evenly. Place the second cake layer on top, then pour the remaining ganache over the top and let it drip down the sides. Allow the ganache to set slightly before serving, or enjoy immediately!
Tips & Variations
- Gluten-Free Option: Easily make this cake gluten-free by swapping the all-purpose flour for a 1:1 gluten-free baking flour blend. Make sure your blend contains xanthan gum for the best texture.
- Vegan or Vegetarian Option: For a vegan version, use plant-based milk (like almond or soy) with vinegar for “buttermilk,” flax eggs (1 tbsp ground flaxseed + 3 tbsp water per egg), and a plant-based oil. Ensure your dark chocolate and butter are dairy-free.
- More Vegetables or Protein: For a healthier twist, you can add 1 cup of finely grated zucchini (squeeze out excess water) to the cake batter for added moisture and nutrients. For a protein boost, serve slices with a dollop of Greek yogurt or a sprinkle of chopped nuts.
