Ingredients
  

  • 1 cup all-purpose flour
  • ½ cup unsweetened cocoa powder
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • ½ cup unsalted butter, softened
  • ¾ cup granulated sugar
  • ½ cup brown sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • ½ cup buttermilk
  • ½ cup hot coffee or hot water
  • 1 ½ cups heavy whipping cream
  • 1 ½ cups semi-sweet or dark chocolate chips
  • 2 tablespoons unsalted butter
  • ½ teaspoon vanilla extract
  • ½ cup heavy cream
  • ½ cup semi-sweet or dark chocolate chips
  • 1 tablespoon butter (for shine)

Instructions
 

  • Preheat the oven to 350°F (175°C). Prepare the cake base by mixing dry ingredients, then adding wet ingredients until smooth. Pour into a greased pan and bake for 25 minutes.
  • Melt chocolate chips with butter until smooth. Whip heavy cream until stiff peaks form, then fold into the melted chocolate until well combined.
  • Spread the mousse over the cooled cake base. Refrigerate for at least 2 hours to set.
  • Top with additional whipped cream and melted chocolate for garnish, if desired.

Notes

For the best flavor, use high-quality chocolate. Allow the cake to chill thoroughly before serving for optimal texture.
