1 Cup Buttermilk (Substitute 1 Cup milk + 1 tbsp Vinegar)
1 1/4 Cup Powdered sugar
1/2 cup Vegetable Oil
1 Tsp Vanilla extract
2 Tbsp water
Prepare your cupcake/muffin pan. I have used mini cupcake pan (24) this time but you can very well use regular size (12)cupcake pan.
In a bowl assemble all the dry ingredients the plain flour, cocoa powder, baking powder and soda together and sieve together once.
Pre heat the oven to 180 C/350 F.
In another bowl put in the milk and vinegar and allow it to sit for about five minutes. Put in the sugar and oil and blend If using buttermilk just add sugar and oil to it and mix and blend. Stir in the vanilla extract.
Now put in the sieved dry ingredients into the liquid ingredients, add the additional 2 tbsp water and blend with a hand blender or stand mixer or even just hands until well mixed about 3 to 4 minutes.
With the help of an ice cream scoop or a spoon drop the batter into the cupcake liners and bake for about 20 minutes for regular cupcakes and 10 mins for mini cupcakes. Make sure you don't fill them more than half.
Now, to bake chocolate cupcakes replace cornstarch with equal amount of cocoa powder and rest of the method will be same.
