Thanks to Joyofbaking.com for sharing this reciepe. The only change I made is to replace half cup yogurt with half cup milk.

Pre-heat the oven to 190 degree C, while we prepare the batter. In a bowl add in all the wet ingredients - Yogurt, milk, egg, oil and vanilla essence. Mix them well and keep it aside.

In another bowl add all the dry ingredients - plain flour, granulated sugar, salt and baking soda. If you want you may sieve all these ingredients to ensure everything is mixed well. Add the blue berries in this mixture and be careful not to break the berries while mixing.

Now gently fold in the wet ingredients mixture that we have in the blue berry mixture. Again be gentle not to break the berries. The batter should be thick as shown in the demonstration below.

I have lined the cup cake molds with muffin paper cups/paper liners instead of greasing the molds with butter/oil. Fill the paper liners with the batter and bake them for 20 mins or until toothpick inserted in the muffins comes out clean.
