Prepare the Cake

• Stack and fill your cake layers.
• Apply a crumb coat (thin layer of buttercream to trap crumbs). Chill 15–20 minutes.

Mix Your Shimmer Paint

• In a small dish, mix a little lustre dust with rejuvenator spirit.
• Aim for a smooth paint consistency (not too watery).

Paint the Inside of the Piping Bag

• Take a clean piping bag.
• Use a brush to paint stripes or swirls of the shimmer mixture on the inside walls of the bag.
• Focus on the areas where the buttercream will press against as you pipe.
• Tip: You can do straight stripes for a streaky shimmer, or coat the whole inside for an all-over glow.

Fill with Buttercream

• Gently spoon your buttercream into the painted piping bag.
• Try not to smear too much, so the shimmer stays on the walls.

Pipe Your Decorations

• As you pipe swirls, rosettes, or borders, the buttercream will come out with the shimmer dust already embedded in it, giving a metallic or pearly glow.
