White Chocolate Chip & Chocolate Chip Muffins

My son has been pestering me to make him muffins for over a month, and due to various reasons kept postponing his request. Until  I get a December letter from his play school announcing one of the days as 'Picnic day' with specifics to snacks, a mat, paper plates and cups to be brought along as the paraphernalia. My son couldn't have have had better reasons to take along with him 15 muffins for his friends, with my constant reminder "Elijah you got to share with your friends" to which he promptly responds "No, Mama I can't - Please..."!!
At the end of the day he indeed shared his muffins with all his little friends. Ria is hosting the mingle for the month - Chocolate Extravaganza, and I'm sending this across as my entry.

Ingredients:
Plain Flour – 215gm

Baking Powder – 1 tsp

Butter/Margarine – 115gm

Caster Sugar – 70gm
Dark Brown sugar – 30gm
Eggs – 2
Milk – 125ml
White Chocolate Chips – 85gms
Chocolate Chips – 85gms (I used a semi sweet chocolate bar and cut them into pieces)

Preheat the oven to 180C. Grease 10 – 12 silicone muffin cases/ paper cups or the muffins tray. Cream the butter until soft. Add both sugars and beat until light & fluffy. Beat in the eggs 1 at a time. Sift together the flour & baking powder, twice. Fold into the butter mixture, alternating with the milk. Spoon the mixture three fourths full into the muffin cases. Sprinkle several chocolate chips on top. Bake until lightly colored , about 25 minutes.
