  • 4 oz dark bittersweet chocolate coarsely chopped, 113g
  • 1/2 cup unsalted butter cut into pieces, 113g
  • ½ cup cocoa powder 50g
  • ¾ cup sugar 150g
  • 1 tsp espresso powder optional
  • ¼ tsp salt
  • 4 large eggs

Optional toppings

  • cocoa powder
  • berries
  • ganache
  • powdered sugar


  • Preheat to 360F, butter an 8 inch cake pan and line with parchment paper.
  • Chop chocolate and butter then place in a bowl over a pot of simmering water and melt stirring occasionally. Sift in the cocoa powder, whisk in the sugar, salt, espresso powder and eggs mix very well. You may add a teaspoon of vanilla at this point but it is optional.
  • Pour into prepared pan and bake at 360f for 22-25 minutes. The top will have a crust and the edge will have risen and set.
  • Allow to cool in pan for a few minutes then run a knife along the edge and invert onto a cake plate. Allow to cool then dust with powdered sugar, cocoa or cover in ganache. Top with berries and enjoy!



  • An 8-inch cake pan works best, if you use a larger pan it will result in a thinner cake.
  • Use good quality chocolate and cocoa powder for best results.
  • Make sure to use a chocolate bar and not chocolate chips or candy melts because they contain additives that stop the chocolate from melting in a silky soft consistency.
  • If using semisweet chocolate reduce the amount of sugar to 2/3 cup.
  • There's no need to bring the butter to room temperature for this cake because it's melted with the chocolate.
  • I use unsalted butter because salt is added in separately. If you use salted butter make sure to reduce the added salt.
  • Make sure to grease the cake pan and line it with parchment paper so the cake doesn't stick.
  • Let the cake cool completely before adding any toppings.
