Ingredients
  

  • 400 grams Digestive Biscuits trust me, it's actually really good when you use these
  • 1 cup Walnuts Roasted and chopped
  • ¾ cup Cane Sugar
  • 7 tbsp Hershey Cocoa Powder can use any cocoa powder
  • ¾ cup Water
  • 1 tsp Vanilla extract
  • 1 tbsp Strong brewed coffee

For the Ganache

  • 1 cup Heavy whipping cream
  • 200 grams Dark chocolate I used Ghirardelli

Instructions
 

Now, let's mix and set the cake!

  • Heat a pan, dry roast the walnuts in a low flame till it gives a nutty smell which is within 5 mins.
  • Chop the walnuts into small pieces.
  • The next step would be to butter the cake pan on all sides and keep it aside.
  • In a pan, add the sugar and cocoa powder. Mix it well using a whisk.
  • Gradually add water and stir well
  • Place it over medium heat. Add butter (cut into pieces so it melts quickly) and vanilla extract.
  • When the butter is melted, add trong brewed coffee to the mixture and keep mixing well for about 5 minutes. Keep it aside and let it cool a bit.
  • Pour the chocolate syrup over the biscuits and mix well.
  • Add most of the chopped walnuts (leave some to garnish on the cake) and mix it along with the biscuits and the syrup.
  • Transfer the mixture into the buttered cake pan.
  • Press down the biscuit mixture evenly and refrigerate for 30 minutes.
  • Break the cooking chocolate (I use DARK chocolate ONLY) and keep it aside.
  • Heat a pan, pour a cup of heavy whipping cream in it.
  • Add the chocolate pieces.
  • Stir until smooth.
  • Looks smooth and silky.
  • Pour ganache over the chocolate biscuit cake evenly. Remember to lick the leftover sticking to the pan :))
  • Garnish with toasted chopped walnuts on top and refrigerate for 4 hours for it to set well.
  • Of course, serve it with whipped cream and enjoy till the very last bite – sharing is optional 🙂
