Preheat oven to 180 degree C. Line a muffin tray with cupcake cases.
Take curd, sugar, oil,vanilla in a bowl. Whisk it well.
Add in baking soda and baking powder and whisk it up. It will turn foamy and frothy.
Add in flour and fold gently.
Add in chocolate chips and fold gently.
Scoop the batter into moulds using icecream scoop, Sprinkle some chocolate chips on top.
Bake them 20 to 25 mins or insert a toothpick to see whether it is cooked, if it comes out clean then it is done.
Remove them and let it cool completely.
Serve.
Notes:
1)It is best to make half the batch of this if you have only 6 cup muffin mould because if you let the batter sit for a while then it may not rise that much.
