Chop the white chocolate into small pieces, then melt it over a double boiler. Stir constantly to prevent burning, until completely smooth and liquid.
Combine the egg yolks with the brown sugar and vanilla sugar, and whisk until pale and fluffy. Ensure it is well combined, without any lumps.
Pour the freshly brewed coffee into the chocolate and egg mixture, and stir until smooth. In a separate large bowl, whip the heavy cream until soft peaks form.
Gently fold the whipped cream into the chocolate and coffee mixture. Be careful not to deflate the cream and lose its airy texture.
Once well combined, pour the mixture into a suitable container and place it in the freezer for at least 4 hours to allow the parfait to solidify.
Before serving, remove the parfait from the freezer and sprinkle the top with grated white chocolate for an extra chocolatey flavor.
