Method

  1. Make up a batch of the vanilla cookie dough.
  2. Separate into 6 balls and colour each one by working a few drops of food gel into the dough. The dough may get a little wet so you can balance it out with a little extra flour.
  3. Wrap the balls in cling film and leave to chill in the fridge for 20 mins.
  4. Roll out each ball of dough to about 2mm thick. Cut strips of dough (one from each colour) and assemble into the shape of a rainbow. We ran ours along the inside of a circle cookie cutter to get the rounded shape. Press down lightly on the joins of the strips to fix them together.
  5. Bake for in the oven at 160°C/320°F/Gas Mark 3, checking after 12 mins. You don't want the cookies to brown and lessen the effect of the colour.

Top tip for making rainbow biscuits

Food gels have less of a flavour then liquid food colourings and don't water down the mixture as much.
