A rich, glossy Chocolate Mirror Glaze that gives cakes a flawless, reflective finish and a deep, luxurious chocolate flavor. Smooth, elegant, and easier to make than it looks — perfect for turning any homemade cake into a showstopper.

Ingredients

1 x 20cm (8-inch) chocolate cake (2 layers)

2 batches Dark chocolate ganache

Gelatine for glaze:

2 1/2 tbsp Cold water

4 tsp Gelatine powder

Mirror glaze:

2/3 cup Water

2/3 cup Pure cream (whipping cream)

1 cup Unsweetened cocoa powder, sifted

1 cup + 2 tbsp White sugar (caster or superfine)

Optional decoration:

Gold dust or gold leaf

Instructions

  1. Refrigerate the cake layers for at least 1 hour. Trim and frost with chocolate ganache until smooth, then refrigerate again for at least 1 hour before glazing.
  2. Bloom the gelatine by sprinkling it over cold water and letting it sit for 5 minutes until firm and spongy.
  3. In a saucepan, mix cocoa powder and water into a smooth paste. Add a splash of cream to loosen, then add remaining cream and sugar. Stir gently until combined.
  4. Place the saucepan over medium-high heat and bring just to the boil. Remove from heat and stir in the bloomed gelatine until fully dissolved and smooth.
  5. Strain the glaze through a fine mesh sieve into a shallow bowl to remove bubbles and lumps. Cover with cling wrap touching the surface and cool for about 2 hours until it reaches 30°C (86°F).
  6. Strain again into a jug before using. Place the chilled cake on a wire rack set over a tray. Pour the glaze steadily from the center outward until the cake is fully coated.
  7. Allow excess glaze to drip off for about 10 minutes before transferring to a serving platter. Smooth any imperfections with a warm palette knife.
  8. Decorate with gold leaf or dust if desired, then slice with a warm knife for clean edges.

Notes

Ensure the cake is perfectly smooth before glazing — any bumps will show through.

The glaze should be exactly 30°C (86°F) before pouring for the best finish.

Stir gently to prevent bubbles, and always strain before use.

Add espresso powder for mocha flavor or food coloring for a marbled effect.

Store leftover glaze in the fridge for 1 week or freeze up to 2 months.

Reheat gently before using — do not boil.
