Double Chocolate Sprinkle Cookies

Ingredients
9 oz butter, softened
3/4 cup caster sugar
1/2 cup sweetened condensed milk
2 1/2 cups self-raising flour, sifted
9 oz packet white choc bits
13 oz packet milk choc melts
1/3 cup hundreds and thousands

Directions:
Preheat oven to 400 F. Line 2 baking trays with baking paper.
Using an electric mixer, cream butter, sugar and condensed milk until light and creamy. Add flour and mix on low speed until dough almost comes together.
Stir in choc bits. Roll tablespoons of mixture into balls and place on prepared trays. Bake, 1 tray at a time, for 12 minutes or until light golden. Stand cookies on trays for 5 minutes. Transfer to a wire rack to cool.
Place choc melts in a heatproof, microwave-safe bowl. Microwave, uncovered, on HIGH (100%) in 30 second bursts, stirring every 30 seconds with a metal spoon, until smooth. Spoon melted chocolate into the centre of each biscuit. Sprinkle with hundreds and thousands. Allow to set. Serve.
