A white mirror glaze cake is pure edible artistry—a dessert so sleek and reflective, that it looks like it belongs in a high-end pastry boutique. Inspired by the delicate, glass-like finishes of French pâtisserie, this cake transforms a simple sponge into a mesmerizing centerpiece.
Whether you’re celebrating a special occasion or just want to master a professional technique at home, this recipe is a rewarding (and delicious) challenge. The secret to achieving that flawless, mirror-like shine? Precision and patience.
A silky blend of white chocolate, condensed milk, and gelatin creates a glaze that drapes effortlessly over a chilled cake, forming a glossy, opaque finish. The best part? It pairs beautifully with just about any cake flavor—classic vanilla, rich chocolate, or even a tangy citrus sponge for contrast.
Mastering mirror glaze may seem intimidating, but with a few pro tips—like straining the glaze for a smooth pour and getting the temperature just right—you’ll create a masterpiece every time.
Experiment with subtle flavor infusions like almond or coconut for added depth. Once you see your reflection in that pristine white sheen, you’ll know you’ve nailed it.

White Mirror Glaze Cake Recipe
Equipment
- Medium saucepan
- Digital thermometer (optional)
- Hand blender
- Wire rack with a baking sheet
- Offset spatula
- Large mixing bowl
Ingredients
- 150 g Sweetened condensed milk
- 120 g Water
- 240 g Glucose
- 15 g Unflavored gelatin
- 275 g White chocolate
- 60 g Icy cold water for gelatin powder
- 250 g Granulated sugar
Instructions
- Bloom gelatin by mixing powder with icy-cold water and letting it hydrate for 10 minutes, or soak gelatin sheets in cold water for the same time.
- Heat water, sugar, and corn syrup in a saucepan over medium heat, stirring occasionally, until it reaches 217°F (103°C) or starts bubbling hard.
- Remove from heat and stir in sweetened condensed milk until well combined.
- Add the bloomed gelatin and mix until fully dissolved.
- Pour the hot mixture over white chocolate in a large bowl, stir, then emulsify with a hand blender, keeping the blender slightly tilted to minimize air bubbles.
- Optionally, add food coloring.
- Allow the glaze to cool to 86-95°F (30-35°C).
- The ideal temperature depends on the environment, but around 91°F (33°C) works well.
- Place the frozen cake on a wire rack over a baking sheet.
- Remove from the mold and ensure it is solidly frozen.
- Pour the glaze generously over the cake in a circular motion, covering the sides evenly.
- Use an offset spatula to smooth the surface and remove excess glaze.
- Trimming any excess glaze from the bottom for a clean finish.
- Once dripping stops, transfer the cake carefully onto a serving plate or cake board.
Notes
- Ensure gelatin is fully bloomed to achieve a smooth, stable glaze.
- Blend at a slight angle to reduce air incorporation, which can cause an uneven surface.
- A frozen cake allows the glaze to set quickly and smoothly.
