Preheat the oven to 180C for 15 minutes. Line a 12 cup muffin pan with paper liners or grease it with non-stick cooking spray.
In a bowl mix all the dry ingredients until combined well.
Add the wet ingredients to the bowl and mix until smooth.
Pour the batter in the prepared muffin pan.
Bake for 20-25 minutes or until a toothpick inserted in the centre of the cup cake comes out clean.
