• 1 tsp Baking soda
• 1 tsp Baking powder
• 0.5 tsp Salt
• 3 large Eggs (room temperature)
• 1 cup Whole milk (plus 1 tbsp vinegar to make buttermilk)
• 1 tbsp White vinegar
• 0.5 cup Vegetable oil (neutral flavor)
• 2 tsp Vanilla extract
• 1 cup Strong brewed coffee (hot, enhances chocolate flavor)
• 8 oz Dark chocolate (70% cocoa) (grated on microplane)
• 1 cup Powdered sugar (sifted)
• 2 tbsp Cornstarch
• 0.5 cup Cocoa powder (for frosting) (sifted)
• 1 tsp Espresso powder
• 4 tbsp Unsalted butter (softened)

Instructions

1. Preheat Oven

   Set the oven to 315°F (160°C) and let it fully preheat.

   Time: PT5M

   Temperature: 315°F

2. Make Buttermilk

   Combine 1 cup whole milk with 1 tbsp white vinegar in a small bowl. Stir and let sit for 5 minutes until it curdles.

   Time: PT5M

3. Sift Dry Ingredients

   In a large mixing bowl, sift together 2 cups flour, 1½ cups sugar, ¾ cup cocoa powder, 1 tsp baking soda, 1 tsp baking powder, and ½ tsp salt. Whisk to combine.

   Time: PT5M

4. Combine Wet Ingredients

   Add 3 large eggs, the curdled milk, ½ cup vegetable oil, 2 tsp vanilla extract, and 1 cup hot brewed coffee to the dry mixture. Whisk until just combined; the batter will be thin and glossy.

   Time: PT5M

5. Prepare Pans and Divide Batter

   Grease two 9‑inch round cake pans with butter or non‑stick spray, then line the bottoms with parchment. Pour the batter evenly into the pans and tap gently to release air bubbles.

   Time: PT5M

6. Bake Cakes

   Place the pans in the preheated oven and bake for 70‑75 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.

   Time: PT1H15M

   Temperature: 315°F

7. Grate Chocolate for Ganache

   While the cakes bake, grate the 8‑oz dark chocolate on a microplane until it becomes fine dust. Set aside.

   Time: PT5M

8. Mix Ganache Dry Ingredients and Water

   In a medium sauce pot, whisk together 1 cup powdered sugar, 2 tbsp cornstarch, ½ cup cocoa powder, 1 tsp espresso powder, and a pinch of salt. Slowly whisk in 1 cup water until smooth.

   Time: PT5M

9. Cook Ganache to Pudding Consistency

   Place the pot over medium heat, stirring constantly with a rubber spatula. Cook for about 10 minutes, or until the mixture thickens to a pudding‑like texture and pulls away from the sides of the pot.

   Time: PT10M

10. Add Grated Chocolate and Butter

    Remove the pot from heat. Stir in the grated chocolate until fully melted and smooth. Then whisk in 4 tbsp softened butter until the ganache is glossy and glossy.

    Time: PT5M

11. Cool Ganache

    Transfer the ganache to a shallow bowl, cover with plastic wrap touching the surface, and let it cool to room temperature (about 15 minutes) until it thickens enough to spread.

    Time: PT15M

12. Level and Stack Cakes

    Using a cake leveler or serrated knife, trim the tops of each cake layer to make them flat. Place the first layer on a cake stand, spread a generous scoop of ganache over it, then repeat with the second layer.

    Time: PT10M

13. Finish Frosting and Serve

    Using an offset spatula, swirl the remaining ganache around the sides and top of the cake. For a smooth finish, rotate the cake stand on a lazy‑Susan and smooth with gentle strokes. Let the cake sit for 10 minutes before slicing.

    Time: PT5M
