Preheat oven to 190°C (170°C Fan, Gas Mark 5) and line 2 baking trays with baking parchment. Cream together the butter, sugar and Vanilla Extract until pale and smooth.
Add the flour and mix well until a crumbly dough is formed. Add the milk and mix until the dough comes together.
Finally stir through the Chocolate Chips. Divide the dough into 16 equal portions roll each portion into a ball. Place on the baking tray. Bake for 12-15 minutes until slightly golden in colour, the cookies will still be soft but they will firm up as they cool.
Once the cookies have cooled melt the white chocolate in the microwave, heat for 30 seconds then stir and heat in 10 seconds bursts stirring between each burst until it is melted. Dip half of each cookie in the white chocolate and place on some greaseproof paper to set. Sprinkle with Bright and Bold sprinkles to finish!
