Chocolate double choc chip and peanut biscuits

Ingredients

200g chopped butter
3/4 cup caster sugar
3/4 cup brown sugar
2 eggs lightly beaten
2 cups SR flour

Just under 1/2 cup white choc bits

Just under 1/2 cup dark choc bits
Just under 1/2 cup roasted peanuts (not salted) see note below

Method

1. Beat butter, sugars and eggs with electric beaters
2. Stir in remaining ingredients
3. Roll into teaspoon sized balls
4. Cook in a moderate oven for 15 minutes
5. Take out of oven but leave on the tray for a little while before putting on wire rack to cool (biscuits come out of oven a little soft)

Note
I used raw peanuts and roasted them myself in the oven for about 10 minutes.

I have no ideas where I got this recipe, it is handwritten in my recipe book.
