What you will need:

256g of icing/confectioner's sugar
1 egg white
1 tablespoon of room temperature water
colourings and flavourings (We recommend flavourings by Foodie Flavours and colourings by Americolor or Squires Kitchen)
Parchment paper
Piping bags fitted with small writing tips (We recommend Wilton round tips 3-6) 

Step one: Combine all of the ingredients (except the colourings and flavourings) together in a large bowl. The mixture will become thick and sticky so be prepared for a little work.

Step two: Now you can add whatever colour or flavour you wish to the mixture.

Step three: If you require multiple colours divide the mixture into separate bowls.

Step four: Fill your piping bag(s) with your sprinkle mixture and pipe long lines or dots onto a flat surface with parchment paper. Note: If you make dots they will end up having the shape of chocolate chips.

Step five: Leave to dry out for 24 hours (This is essential!) and then you can chop them up using a spatula. 

Step six: Now sprinkle onto your baked goods and enjoy!
