Chocolate Chip Muffin

I have recently purchased these beautiful cupcake liners from Ikea. They cost $1.90 for 65 pcs and there are 3 designs in 1 box. The size of these are slightly different from those you get from Phoon Huat. These come with a smaller base of about 1.5" and has a hight of about 2.5".
Here is the recipe for the cupcakes:

120g plain flour

70g sugar
1tsp baking soda
1/4tsp salt
150g plain yogurt
1 egg
50g canola oil
1 tsp vanilla essence

Method:- Preheat oven at 180C
- Mix dry ingredients together
- Mix wet ingredients in another bowl
- Pour wet ingredients into the dry ingredients and mix gently.
- Scoop into cupcake liners 3/4 full.
- Bake for 15mins.

* Word of caution - Do not over mix if you want tender muffins.
