In a large bowl, sift together flour and cocoa powder.
Add sugar, baking soda, salt and whisk to combine all dry ingredients together.

Take 1 cup milk then add 1 tablespoon white vinegar to it. Let it sit for 5-10 minutes. You can also use 1 cup buttermilk but I used milk.

After 10 minutes, add oil and vanilla extract to the milk-vinegar liquid. Stir to combine.Add the wet ingredients to dry, mix till the ingredients are just combined.Add 2 tablespoons of water at this point if the batter seems too thick. This is optional, I did't add it to my batter. Remember to not over-mix the batter.Fill the prepared cupcake liners ½ full with the cupcake batter.

Bake at 180 deg. for 20-25 minutes or till a toothpick inserted in the center comes out clean.Remove from oven, transfer to a wire rack and let the cupcakes cool completely.

Now decorate with whipped cream and serve.
