Preheat the oven to 180 degrees celsius. Place the rack in the middle of the oven.
In a large bowl, combine all the dry ingredients and mix well.
Take two 8-inch baking pans. Oil or butter it on all sides and add a parchment paper on top. Keep it aside.
Weigh all the ingredients as per the recipe and keep them ready before you start making the cake.
In a large bowl, take two eggs and whisk it till slightly frothy. Add the rest of the wet ingredients and mix well.
Pour the wet ingredients into the dry ingredients and mix till you get a thin batter (see video).
Pour the batter equally onto each baking pan. Measure the weight on a machine to get the exact proportions.
Bake at 180 degrees for 25-30 minutes. Check if done by inserting a toothpick. If it comes out clean, it means the cake is cooked.
Let the cakes cool for 20 minutes. Invert and take them out on a plate or cake base. Allow them to cool completely.
Make a double boiler by heating water in a sauce pan and placing a heatproof bowl above it (see video). Now add the semi sweet dark chocolate chunks and butter. Let it melt in lowest heat. Once the chocolate is completely melted, mix well and set aside. Cool completely.
In a bowl, whip the cream with an electric beater till stiff peaks are formed. Add the cooled chocolate to the whipped cream and fold gently. This is the frosting.
Apply the frosting on th cake as shown in the video. Enjoy!
