Steps
  1. subheading: FOR THE CAKE:
  2. Grease and line 4 to 4 inch round cake pans with parchment paper. Set aside.
  3. Preheat oven to 350 degrees F.
  4. In a large mixing bowl, whisk together flour, sugar, cocoa, soda, baking powder, and salt.
  5. Add egg, oil, and buttermilk and whisk well.
  6. Add hot coffee and whisk until the batter is smooth.
  7. Pour into prepared pan. Tap gently against the counter to release any air bubbles.
  8. Bake for 30 to 35 minutes OR until the toothpick inserted in few places comes out clean.
  9. Cool and make frosting in the meantime.
  10. subheading: FOR THE FROSTING:
  11. With a handheld or stand mixer fitted with a paddle or whisk attachment, beat the butter on medium speed until creamy - about 2 minutes.
  12. Add confectioners’ sugar, cocoa powder, heavy cream, salt, and vanilla extract. Beat on low speed for 30 seconds, then increase to high speed and beat for 1 full minute.
  13. Add ¼ cup more confectioners’ sugar or cocoa powder if frosting is too thin or another tablespoon of cream if frosting is too thick. Taste. Beat in another pinch of salt if desired.
  14. For a darker black color, add in a few drops of black food coloring. Making the frosting a day in advance also deepens the black color as the frosting sits.
  15. subheading: FOR THE GANACHE:
  16. Add the chocolate chips to a medium sized bowl and set aside.
  17. Add the heavy whipping cream to a microwave safe bowl or measuring cup and heat for about 1 minute, keeping an eye on it. If it heats up too much, it’ll end up everywhere. Remove from the microwave just before it bubbles up.
  18. Pour the warm cream over the chocolate chips and allow to sit for 3 to 5 minutes. You can cover the bowl with some clear wrap to trap in the heat, if you like.
  19. Gently stir the cream and chocolate together until they come together to a smooth consistency. Try not to whisk too vigorously, which can add air bubbles to the ganache.
  20. If making white chocolate ganache and you have some lumps remaining, heat in 10 second increments, stirring between, until ganache is smooth.
  21. Allow ganache to cool for about 10 minutes, give or take, prior to using. Color to your desired hue.
Notes
