Preheat your oven to 175 degrees Celcius.

Mix sugar, egg and butter in a bowl.

Mix baking powder, salt and flour in another bowl, before you mix it all together.

Separate the dough into 4, and put each dough in a bowl.

Mix the colour and the dough.

Separate the coloured doughs into 15 blobs.

Make a "snake" of every blob.

Put 4 "snakes" together, one of each colour.

Make the four-coloured "snakes" longer by rolling them carefully.
I think a length of 15 cm would be good.

And now for the tricky part.

Have your roasting tray ready.

Twist the "snake" while your making a spiral of it on your roasting tray.

It might take a little practice. :-)

Make spirals of all 15 "snakes".

Bake the cookies for 10-12 minutes.

And DONE ... Ready to eat!

... And that is how the cookie crumbles. :)
