I’m coming clean with you about decorating with luster dust … I’m still learning and I have made mistakes …Gasp! Luster dust adds the finishing touch and creates a shimmer to a cookie but it can be tricky to work with. Dry luster dust is applied with a small paintbrush, creates a matte finish and is easy to apply. A shiny finish is achieved by adding liquid to the luster dust to create a paint-like consistency. This method can be challenging and has a bit of a learning curve.

Brushing too much wet luster dust onto a cookie can degrade the royal icing as in this photo.

Dab the excess from the brush before application to achieve a better result as in this photo.

To conceal mistakes on a cookie as in the first photo, 
turn to a cookie decorator’s friend ... sanding sugar. No sign of a mistake here!

These cookies were inspired by the December issue of Bon Appetit Magazine.

  4. These are quite pretty. You are right, it does take a bit of practice when working with luster dust and sanding sugar has been a saving grace in many *practice session* :)

    1. Paula, Thank you! I need more practice to get the right consistency for painting with luster dry. I'm still trying to achieve the smooth finish that Amber demonstrates.
