Cream butter for 3 minutes at medium high speed until creamy. Add icing sugar and increase to high speed. Mix well until light and creamy and icing sugar is no longer visible. Don’t forget to scrape down the sides of your mixing bowl from time to time.
Add egg yolks, one at a time, then beat well until just combined. I recommend you to weigh the egg yolks beforehand as this will determine the consistency of the cookie dough.
Add in milk, a little at a time, as you continue to beat everything together on high speed for 3 minutes. Whip until the texture becomes fluffy. Scrape down the sides of your mixing bowl.
Fold in milk powder, corn flour and cake flour. Using a baking spatula, gently fold in all the ingredients together, stirring firmly until well combined to form a soft, pliable dough.
You can use a 1.5cm piping tip (those ideal for making churros), but I prefer the Wilton 1M nozzle to achieve a thinner, more organic shape. Fit your nozzle to your piping bag then transfer the dough to the bag. Do not overfill. Kitchn has some great tips on how to use a piping bag for beginners (link below).
With a firm hand, gently press down the tip of your nozzle to a baking tray lined with parchment paper. Pipe out ’S’ patterns, using your thumb to press them out of the nozzle. Try to keep to an S shape as much as possible and don’t pipe too long, otherwise it may end up looking like a snake instead of a dragon.
Use a toothpick dip in red gel colouring to dot the eyes.
Cover with a plastic wrap and refrigerate cookie dough for 30 minutes before baking.
Preheat oven to 150 C. Bake your cookies on the lower rack for 15 minutes till light yellow. It shouldn’t brown too much.
Remove and leave to cool on a cooling rack.
