Instructions

Make the Cake

  • Prep pans and oven. Grease three six inch round pans and line bottoms with parchment. Heat oven to 350°F.
  • Dry mix. In a medium bowl whisk flour, cocoa, baking powder, baking soda, and salt until evenly combined.
  • Wet base. In a large bowl whisk both sugars with eggs until slightly thick and lighter in color, about 2 minutes by hand or on low speed. Whisk in oil, buttermilk, and vanilla until smooth.
  • Combine. Sift the dry mixture into the wet and whisk gently just until combined. Scrape the bowl.
  • Bloom cocoa. Slowly stream in hot coffee while whisking on low. The batter will be thin.
  • Bake. Divide evenly into the pans, about 400 g batter per pan. Tap gently to release bubbles. Bake 25 to 30 minutes until tops spring back and a tester comes out clean.
  • Cool. Rest 10 minutes in the pans, then turn out to racks and cool completely.

Make the Whipped Ganache Frosting

  • Place finely chopped chocolate in a heatproof bowl.
  • Heat cream until just steaming. Pour over chocolate, cover, and rest 2 minutes.
  • Whisk from the center until glossy and smooth.
  • Add butter and a pinch of salt and whisk until incorporated.
  • Cover and cool at room temp until thickened and spreadable, about 1 to 2 hours, or chill about 30 minutes, stirring once.
  • For a lighter texture, whip briefly with a mixer until just lightened and soft peaks form. Do not overwhip.

Make the Salted Chocolate Crumble

  • Heat oven to 325°F. Line a small baking sheet with parchment.
  • Whisk flour, cocoa, sugar, and salt in a bowl.
  • Drizzle in melted butter and stir with a fork until clumps form.
  • Scatter on the sheet and bake 15 to 18 minutes, stirring once, until dry and crunchy.
  • Cool completely and break into small crumbs.

Assemble and Finish

  • Level cake layers if needed.
  • Set the first layer on a stand and spread about ½ cup whipped ganache. Add the second layer and repeat.
  • Top with the third layer. Spread a thin crumb coat and chill 20 minutes.
  • Frost the cake with the remaining ganache with smooth or swooped sides.
  • Finish with a generous crown of salted chocolate crumble on top. Slice and serve.

Notes

  • Eight inch option. Divide batter into three eight inch pans for thinner layers. Bake 18 to 24 minutes and handle gently since the layers are more delicate.
  • Coffee swap. Use boiling water if you prefer no coffee. Flavor will be slightly lighter but still chocolate forward.
  • Even layers. Scaling about 400 g batter per pan gives a neat, level stack.
  • Make ahead. Wrap cooled layers and refrigerate up to 2 days or freeze up to 1 month. Ganache can rest covered at room temp up to 1 day before whipping.
  • Fixes. If ganache is too soft, chill 5 to 10 minutes and stir. If too stiff, warm the bowl for a few seconds and stir until smooth.
  • Storage. Keep the finished cake covered at cool room temp up to 1 day or refrigerate up to 4 days. Bring slices to room temp for the best texture.
    Crumble placement. The crumble is a topping only for crunch and contrast.
