Ingredients
Method
- Start by making the ganache so it has time to cool. In a microwave-safe bowl, combine the heavy cream and chopped chocolate. Microwave in 15-20 second intervals, stirring between each, until the chocolate is almost melted. Continue stirring until fully melted and smooth. If needed, microwave for an additional 10-15 seconds. Be cautious not to overheat.

- Cover the ganache with a plate and set it at room temperature to cool for 1.5 to 2 hours, stirring every 30 minutes, until thickened to a spreadable consistency.
- Preheat your oven to 350°F (175°C). Prepare two 8-inch or 9-inch round cake pans by greasing them with butter or oil and lining the bottoms with parchment paper.
- In a large bowl, combine the sifted flour, sugar, baking powder, baking soda, and salt. Stir until well blended.
- Crack the eggs into the dry ingredients and add the vegetable oil and buttermilk. Mix gently with a whisk until smooth and no lumps remain.

- In a small bowl, combine the cocoa powder, instant coffee (optional), and boiling water. Stir until smooth and glossy. This step brings out the full chocolate flavor.
- Add the bloomed cocoa mixture into the cake batter. Stir gently to combine. Be careful not to overmix as this could result in a tough cake. The batter will be thin, which is normal.
- Divide the cake batter evenly between the prepared pans. Bake for 20-25 minutes if using 9-inch pans, or 23-28 minutes for 8-inch pans. Check for doneness by inserting a toothpick into the center of the cakes. It should come out with a few moist crumbs (not wet batter), and the cake should spring back when lightly touched.

- Let the cakes cool in the pans for 10-15 minutes, then transfer to a wire rack to cool completely. Handle with care to avoid breaking the delicate cakes.
- Once the cakes and ganache have cooled, carefully trim the domes off the cakes with a serrated knife. Place one cake layer on a serving platter or cake stand. Spread ⅓ of the ganache on top, smoothing it with an offset spatula.

- Place the second cake layer on top and cover the entire cake with the remaining ganache. For a rustic finish, use the spatula to spread the ganache evenly over the top and sides. If you want to avoid crumbs in the frosting, apply a thin crumb coat first, refrigerate for 15 minutes, and then apply the final layer of ganache.
- Slice and serve the cake at room temperature. Enjoy!
