Preheat the oven at 180 degrees Celsius for 10 minutes. Line a muffin tray with cupcake liners.
Sieve all the dry ingredients together twice and set them aside.
Whisk the wet ingredients together.
Add the dry ingredients to the wet ingredients and whisk well to make a smooth batter. If the batter is too dry add 1-2 tbsp milk to make it smooth and lump free.
Fill each cupcake liner in the prepared tin with the batter up to 2/3rd of their capacity. Pat the tray lightly on the platform to release any air bubbles.
Bake at 180 degrees Celsius for 20-25 mins. To check if it's cooked, insert a toothpick in the centre of a cupcake, it should come out clean or with a few moist crumbs. Adjust the timing & temperature as every oven works differently.
Cool thoroughly before serving. They can be stored up to 3 days in an airtight box.
