  • 2 cups semisweet chocolate chips divided
  • ½ cup butter
  • ¾ cup sugar
  • Pinch salt
  • 1 tsp instant coffee
  • 1 tsp vanilla
  • 3 eggs room temperature
  • ½ cup cocoa powder
  • ½ cup heavy whipping cream


Make the Cake:

  • Preheat the oven to 375 degrees.
  • Grease an 8” round cake pan. Cut a circle of wax paper to fit bottom of the pan. Insert the wax paper and grease it as well.
  • Place 1 cup of the chocolate chips and the butter in a medium sized microwave-safe bowl. Microwave in 30 second increments, stirring after every 30 seconds, until the butter is melted. Stir until the chocolate chips melt and combine with the butter.
  • Stir in the sugar, salt, coffee, and vanilla.
  • Switch to a whisk and whisk in the eggs until the mixture is smooth.
  • Add the cocoa powder and whisk just until combined.
  • Spoon the batter into the pan. Bake for 25 minutes. The top will form a thin crust.
  • Remove from the oven and cool in the pan for 5 minutes. Loosen the edges of the cake from the pan with a sharp, thin knife. Invert onto a serving plate (note: the edges may crackle a bit). Allow the cake to cool completely before proceeding.

Make the ganache:

  • Combine the remaining 1 cup chocolate chips and heavy whipping cream in a microwave-safe bowl.
  • Heat until the cream is hot but not bubbling.
  • Stir until the chocolate chips melt and the mixture is very smooth.
  • Pour the ganache over the top of the cake, spreading just to the edges.
  • Allow the ganache to set for several hours (refrigerated or not) until ready to serve.
