When I first posted this Rainbow cookie recipe to Instagram I joked that they were made with real unicorn. This was, of course, just a joke. No unicorns were harmed in the making of these cookies.

These cookies generally have quite gentle pastel colours, so would be good for Easter Parties. And if we still can’t have parties by Easter, you’ll just have to eat them all yourself!
You could also make Pride Cookies with this method, just roll flat strips instead of sausages and lay them on top of each other.
Rainbow Cookie Recipe
Ingredients
1 cup Butter,
1.5 cups Sugar,
1 Egg,
1 tsp Vanilla essence (optional, but if using margerine, recommended)
2.5 cups Flour, All-purpose or plain,
1 tsp Bicarbonate of soda,
0.5 tsp Baking powder,
Food colouring,
Method
Cream butter with the sugar. Gradually add in the egg and vanilla essence. If you add the egg too fast the mix will split, sprinkle a little of the flour in if this happens.
Add the rest of the flour and the raising agents, mixing very well with a wooden spoon. Once the dough is an even consistency divide into roughly equal portions. Add the food colouring a drop at a time and knead it into the dough until the colour is no longer marbled. Keep going until you are happy with the colours, but remember that you’re mixing the colours with the pale dough, so you’ll never get dark colours this way, if you add too much colouring your dough will be wet.
Once you have all the colours you want roll them into sausages and then twist the sausages together into one big multicolour sausage and roll into a cylinder. Then chill in the fridge or freezer until the dough firms up.
Preheat the oven to 375 °F/190 °C/gas mark 5. Once your dough sausage is firm, take a sharp knife and slice disks of rainbow off the sausage. Place on a baking tray. Bake for 10-15min, until they start to turn golden at the edges. Remove to a cooling rack.
