  • Pour the mousse mixture into a 7 to 9-inch springform pan that has been coated with cooking spray or canola oil and is lined with parchment paper. You can also wrap the pan in tin foil on the sides.

  • Chill the mousse overnight in the freezer or refrigerator. Make sure the mousse is completely frozen before adding mirror glaze.

For Mirror Glaze

  • Submerge the gelatin sheets in cool water for 5 minutes if using gelatin sheets.
  • Combine sugar, corn syrup, and water in a saucepan over medium heat and bring to boil until the sugar is totally dissolved.
  • Remove from heat and add the gelatin sheets or gelatin powder. Keep whisking until completely dissolved. Whisk in the sweetened condensed milk. Pour the mixture over the white chocolate. After about a minute, stir until the chocolate is melted and smooth.
  • Set the glaze aside to cool, while making sure to stir occasionally until the glaze reaches approximately 94 degrees on a candy thermometer.
  • Add the food coloring if using to the glaze and stir until desired color is reached.
    preparing the mirror glaze
  • Take unmolded frozen mousse cake and put onto a wire rack with a baking sheet beneath. Pour the mirror glaze over the mousse cake. If too thin, you can pour a second layer after a minute to ensure an opaque glaze.

  • Allow the excess glaze to set for about 10 minutes. Scrape any excess glaze from the bottom edges for a neat finish. If you want to create an accent color, leave a little glaze aside in white or whatever color preferred and pipe onto the set glaze. You can also add glitter, but if using glitter it’s best to add to the glaze before pouring onto the cake. Wrap in plastic wrap and store in the refrigerator for a few days if not serving right away.
