Ingredients
  

For the Cake Batter
  • 1 3/4 cups all-purpose flour
  • 2 cups granulated sugar
  • 3/4 cup unsweetened Dutch-process cocoa powder
  • 2 tsp baking powder
  • 1 1/2 tsp baking soda
  • 1 tsp salt
  • 2 large eggs
  • 1 cup whole milk
  • 1/2 cup vegetable oil
  • 2 tsp vanilla extract
  • 1 cup boiling water
For the Ganache
  • 1 1/2 cups chopped dark chocolate
  • 1 cup heavy cream

Equipment

  • 3 8-inch Cake Pans
  • Mixing Bowls
  • Whisk
  • Saucepan
  • Spatula
  • Wire Rack

Method
 

  1. Step 1: Preheat your oven to 350°F (175°C). Grease and line three 8-inch cake pans with parchment paper.
  2. Step 2: In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
  3. Step 3: Add the eggs, milk, vegetable oil, and vanilla extract to the dry ingredients. Beat until smooth.
  4. Step 4: Gradually add boiling water while mixing on low speed. Batter will be thin.
  5. Step 5: Divide batter evenly into prepared pans and bake for 30–35 minutes, or until a toothpick comes out clean.
  6. Step 6: Cool pans on wire rack for 10 minutes, then remove cakes and cool completely before frosting.
  7. Step 7: Heat heavy cream until it begins to simmer. Pour over chopped chocolate and let sit 5 minutes. Stir until smooth and glossy. Chill until spreadable.
  8. Step 8: Assemble cake by layering cake and ganache, finishing by frosting top and sides with remaining ganache.

Notes
