Ingredients
  

  • cups all-purpose flour
  • 1 cup unsweetened cocoa powder
  • 2 tsp baking soda
  • ½ tsp baking powder
  • 1 tsp salt
  • 2 cups granulated sugar
  • 1 cup packed brown sugar
  • 1 cup buttermilk
  • 1 cup strong hot coffee or hot water
  • ½ cup vegetable oil
  • 3 large eggs
  • 2 tsp vanilla extract
  • 1 cup mini semi-sweet chocolate chips
  • ½ cup chocolate syrup or melted chocolate with 2 Tbsp cream soak
  • 12 oz semi-sweet/bittersweet chocolate ganache
  • cups heavy cream
  • 2 Tbsp unsalted butter
  • cups unsalted butter buttercream
  • 4 –5 cups powdered sugar
  • ¾ cup unsweetened cocoa powder
  • ½ cup heavy cream or milk
  • 2 tsp vanilla extract
  • 1 –2 pints premium vanilla bean or chocolate chip ice cream
  • 1 –1½ cups semi-sweet chocolate chips
  • Chocolate chunks/shavings
  • Extra ganache for drizzling

Instructions
 

  • Preheat oven to 350°F (175°C). Grease and line three 8-inch or 9-inch round cake pans.
  • Whisk flour, cocoa, baking soda, baking powder, and salt.
  • In a large bowl, beat sugars, buttermilk, oil, eggs, and vanilla until smooth.
  • Alternate adding dry ingredients and hot coffee to wet mixture, mixing until just combined. Fold in chocolate chips.
  • Divide batter evenly among pans. Bake 28–35 minutes (toothpick comes out with moist crumbs). Cool in pans 10 min, then turn out onto racks to cool completely.
  • Prepare chocolate soak with syrup/cream and brush over layers once cooled.
  • For ganache: heat heavy cream in microwave or over stovetop, pour over chopped chocolate, add butter, whisk until smooth. Cool slightly before drizzling.
  • For buttercream: beat butter until soft, gradually add cocoa and powdered sugar, alternating with cream/milk. Add vanilla and salt.

Notes

Use Dutch-processed cocoa for deeper flavor.
Substitute coffee with hot water for dietary restrictions.
Check ice cream label for alcohol-free certification.
Cool cake completely before assembling to prevent melting.
Ganache consistency may vary—adjust cream amount as needed.
