Step-by-Step Ultra-Detailed Instructions
Step 1 – Make the White Chocolate Sponge
Whisk eggs and sugar until pale, fluffy, and tripled in volume (~5–6 minutes).
Sift flour, baking powder, and salt; fold gently into egg mixture.
Add melted butter, vanilla, and melted white chocolate; fold carefully to retain air.
Pour batter into prepared pan; smooth surface.
Bake 25–30 minutes until golden and skewer comes out clean.
Cool completely on wire rack before slicing horizontally for layers.
Step 2 – Prepare White Chocolate Filling (Optional)
Heat cream until just below boiling.
Pour over chopped white chocolate; wait 1–2 minutes, then whisk smooth.
Add vanilla; cool to spreading consistency.
Chill slightly before layering on sponge.
Step 3 – Chill Cake for Glazing
Freeze cake layers for 20–30 minutes before glazing.
Slightly frozen surface prevents glaze absorption.
Step 4 – Make White Chocolate Mirror Glaze
Bloom gelatin in cold water 5–10 minutes.
In saucepan, combine sugar, glucose, and water; heat until sugar dissolves.
Add sweetened condensed milk; remove from heat.
Pour over chopped white chocolate; wait 1–2 minutes, then whisk smooth.
Add bloomed gelatin; stir until dissolved.
Add optional white or shimmer coloring; mix evenly.
Strain glaze through fine sieve.
Cool to 30–35°C (86–95°F) before pouring.
Step 5 – Assemble Cake and Glaze
Place first sponge layer on wire rack over tray.
Spread white chocolate filling evenly (if using).
Top with second sponge layer.
Pour mirror glaze slowly over center, letting it flow over sides.
Smooth gently with spatula if necessary.
Let glaze set 15–20 minutes before transferring to serving plate.
Chef Tips
Slightly freeze sponge for better glaze adhesion.
Strain glaze to remove air bubbles.
Pour glaze at correct temperature for best shine.
Use high-quality white chocolate for flavor and gloss.
Common Mistakes to Avoid
Glaze too hot → melts cake surface
Glaze too cold → does not coat smoothly
Sponge not chilled → glaze absorbs unevenly
Air bubbles → strain glaze carefully
