Sieve in all the dry ingredients together at first. Add in ½ cup of All-purpose flour.
Next add in 2.5 tbsp of Cocoa Powder
Next add in ½ tsp of Baking powder and ⅛ tsp of Salt.
Sieve all the dry ingredients together and then set them aside.
In another mixing bowl add in 2 large Room temperature eggs and the Egg Yolk from 1 Egg.
To this add in ¾ cup of Powdered Sugar. Using a hand blender beat everything together until pale. The color of the eggs will slowly change from yellow to pale yellow. It will take about 1 or 2 mins.
To this add in ¼ cup of Cooking oil. Use any oil. I added Coconut Oil.
Now using a hand blender beat everything once again until a thick ribbon consistency. It will take 3 to 4 mins.
The batter will become slightly thick and flowing after beating till the ribbon consistentcy.
Next let's add in the dry ingredients. Slowly add in batches and fold along with the wet ingredients using a whisk or Spatula.
Line a 7 inch round cake pan with parchment paper and transfer the cake batter to it. Tap the cake pan twice or thrice to remove the air bubbles.
Preheat the oven at 180 Deg C for 10 mins and bake the cake at 180 Deg C for 20 to 25 mins. Or till a toothpick when inserted comes out clean.
Allow the cake to cool completely and then run a knife through the edges of the pan. Invert and the cake comes easily out of the cake pan.
