While whipping, gradually add 9 egg yolks, mixing until incorporated after each addition and scraping down the sides of the bowl as needed.
Place 9 egg whites in a separate bowl. Whip until frothy, Gradually add 50 grams of sugar while continuing to whip, until stiff.
Pour the batter onto a 60 x 40 cm sheet pan, lined with parchment paper and brushed with butter. If you don’t have a large sheet pan, you can use two 30 x 40 cm sheet pans.
Bake at 180°C for 8-10 minutes, until light golden brown. Remove from the oven, cool slightly, invert and peel of the parchment paper. Cool completely. Cut into 6 equal parts.
Remove the caramel mixture from the fridge and place in the bowl of a stand mixer. Add 500 ml of cream (min 30 % fat) and whip on high speed until stiff.
Assemble the cake: Spread ⅙ of the caramel frosting evenly over a cake layer. Set another layer on top, and continue layering with the remaining frosting and cake layers.

Soak 5 grams of gelatin sheets in cold water. If you are using granulated gelatin, soak it in 50 ml of cold water.
Combine 10 grams (2 teaspoons) of starch and 30 ml of water in a small bowl, mix and set aside.
Place 150 grams of sugar and 1-2 teaspoons of lemon juice in a saucepan. Heat over medium heat until the caramel melts and turns to a deep amber color.
Remove from the heat. Carefully, gradually add 70 ml of water and 130 ml of heavy cream, stirring constantly. Add a pinch of salt and bring to boil, stirring frequently.
Turn off the heat. Mix the starch and water and add into the hot caramel glaze. Drain the gelatin sheets and add. Stir to combine.
Strain the caramel glaze, and cool to about 30°C.
Glaze the cake: Pour the glaze into the center of the cake, and use a long metal spatula to spread the glaze over the entire cake. The glaze should run down the sides and cover the cake entirely. You can strain the glaze and cover the cake with a second layer.
