How to Use Lustre Dust on Cake Decorations: Dry Brushing vs. Painting

Lustre dust is a fine shimmering powder that gives cake decorations a metallic or pearly finish. A little goes a long way, and there are two main ways to use it.

First: check your label

Not every lustre dust is made to be eaten. Many metallic dusts are labelled non-edible / for decoration only. These are meant for parts that are removed before eating, such as toppers, wired sugar flowers, cake boards and display pieces. Always follow the label on your jar, and when in doubt, keep the shimmer on decorations rather than on the cake itself.

Method 1: Dry brushing (soft shimmer)

1. Make sure your fondant or gum-paste piece is completely dry to the touch.
2. Tap a small amount of dust into the lid, not straight from the jar.
3. Pick it up with a soft, dry brush and tap off the extra.
4. Brush lightly in one direction. Build up layers slowly for a stronger glow.

Best for: a soft, satin sheen on flowers, ruffles and textured details.

Method 2: Painting (bold metallic)

1. Mix a little dust with a few drops of a high-proof clear alcohol or lemon extract until it looks like thin paint. The liquid evaporates and leaves the colour behind.
2. Paint onto the dry decoration with a small, fine brush.
3. Let it dry, then add a second coat if you want a more solid, foil-like finish.

Best for: gold lettering, drips on toppers, and solid metallic accents.

Quick tips

• Work over a sheet of paper so spills are easy to tip back into the jar.
• Keep a separate brush for each colour so gold stays gold.
• Close lids tightly; lustre dust lasts a long time when kept dry.
