To make dacquoise, preheat oven to 200°C. Line 4 baking trays with baking paper. Draw a 20cm x 30cm rectangle on each piece of baking paper.
Sift icing sugar and cocoa into a bowl. Add almond meal and stir to combine.

Gradually add caster sugar, 1 tablespoon at a time, and beat until sugar dissolves and meringue is thick and glossy. Add icing sugar mixture and use a metal spoon to gently fold until just combined. Divide among prepared trays. Using a palette knife, spread meringue over rectangles. Sprinkle evenly with chopped hazelnuts. Bake for 25 minutes, swapping trays halfway through cooking, until dacquoise is dry to touch. Cool.
To make Chuao ganache, place chocolate and glucose in a heatproof bowl. Place cream in a large saucepan over high heat. Bring?to boil. Pour over chocolate mixture and stir with a metal spoon until chocolate melts and the mixture is smooth. Pour into a 20cm x 30cm plastic container or roasting pan. Set aside until ready to assemble.

Place a dacquoise sheet over set Chuao ganache in a plastic container. Spoon over one-third of Gianduja ganache and spread with a palette knife. Top with one-third of Toscano mousse. Repeat layering with remaining dacquoise sheets, ganache and mousse, finishing with a dacquoise sheet . Spread melted chocolate over dacquoise. Cover and place in the freezer overnight to set. Turn onto a clean work surface.
To make the glaze, combine icing sugar and cocoa in a heatproof bowl. Stir in glucose and water until a thin paste forms. Place bowl over a saucepan half-filled with simmering water (make sure bowl doesn’t touch the water). Cook, stirring, for 2–4 minutes or until the temperature of glaze reaches 40°C on a candy thermometer. Remove from heat. Pour over top and sides of torte.
