Vegan chocolate fudge cake with vegan icing

I have been baking something or the other every weekend, but could not post them, for no specific reason. Looks like sheer laziness. Finally got to post a vegan chocolate fudge cake recipe which I adapted from chefinyou. I made this cake for my husband's B'day. I doubled the quantity of the ingredients as there were 11 of us. It was kind of a family get together and we all had a nice time. And yes, everybody loved the cake. I felt the cake was a bit bitter, but it was good to eat with the icing.

I made vegan icing using cornstarch, icing sugar, water and cocoa powder. As the consistency was a bit thin, I added more icing sugar and freezed it for around 5 minutes. Then I could frost the cake without much trouble. I am not sure where I got the icing recipe.
Its better to keep ready the required amount of cold water before proceeding with the cake. Otherwise, there are chances of overlooking "cold" water in the recipe and mixing everything, only to see that cold water is needed to make the batter.(which has happened with me before for another recipe)

Ingredients
All purpose flour/Maida: 3 cups
Powdered sugar: 2 cups
Baking soda: 2 tsp 
Salt: 1tsp 
Cocoa powder: 6 tbsp 
Vegetable oil: 2/3 cup (I used sunflower refined oil)
Vinegar: 2 tbsp (I used apple cider vinegar)
Vanilla essence: 2 tsp 
Cold water: 2 cups

Procedure
1. Pre heat oven to 160 degree C.
2. Sift the dry ingredients in a bowl.
3. In another large bowl mix the wet ingredients and stir well.( I did this with a hand mixer)
4. Add the flour mixture 4 to 5 tbsp at a time to the wet mixture and combine slowly to form a lump free batter.
5. Pour the mixture into the greased(and dusted) cake pan and bake for around 30 minutes or a toothpick inserted in the centre comes out clean.
6. Cool the cake by leaving it aside for 1 minute or so. Then invert the pan over a rack and tap it gently to unmould the cake.
7. Apply the frosting and enjoy.
