Egyptian hazelnut cake (Print Version)

# Ingredients:

→ Hazelnut Cake

01 - 6 egg whites
02 - 6 tablespoons powdered sugar
03 - 1 ½ tablespoons all-purpose flour
04 - 150 g ground hazelnuts

→ Butter Cream

05 - 6 egg yolks
06 - 3 level tablespoons cornstarch
07 - 6 tablespoons granulated sugar
08 - 340 ml milk
09 - 1 teaspoon vanilla extract
10 - 170 g softened butter

→ Caramel and Topping

11 - 200 g granulated sugar
12 - 220 ml heavy cream
13 - 130 g ground hazelnuts
14 - 2-3 tablespoons additional ground hazelnuts
15 - Unsweetened cocoa powder

# Instructions:

01 - Set your oven to 170°C and let it heat up. Lightly grease the base of a 24 cm springform pan and line it with parchment paper. Cut out two more parchment paper circles the same size.
02 - Split the ingredients into three parts. For each layer, combine 2 egg whites, 2 tablespoons powdered sugar, ½ tablespoon flour, and 50 g ground hazelnuts.
03 - Whisk 2 egg whites until they turn fluffy. Gradually add 2 tablespoons sugar while whisking until it fully dissolves. Gently fold in ½ tablespoon flour and 50 g hazelnuts using a spatula.
04 - Spread the batter evenly over the pan base and bake for 20-25 minutes until golden. Do the same for the other two layers, then let them cool on cooling racks.
05 - In a small pot, combine the egg yolks with the cornstarch. Slowly whisk in the sugar and milk until smooth. Bring it to a boil, then lower the heat and stir for 6 minutes. Cool it down with plastic wrap pressed directly onto the surface.
06 - In a nonstick pan, melt the sugar over low heat until it caramelizes without burning. Pour it onto oiled parchment paper in a thin layer and let it harden. Once cooled, crush it into a fine powder using a blender or rolling pin.
07 - Beat the heavy cream until firm peaks appear. Stir in the crushed caramel powder and the ground hazelnuts.
08 - Place one cake layer on a serving plate. Spread a third of the butter cream and a third of the caramel hazelnut mixture on top. Repeat the steps with the other two layers. Use any leftover butter cream to coat the sides.
09 - Place the cake in the fridge overnight so the layers can set and soften.
10 - Sprinkle the edges and top with ground hazelnuts, then dust cocoa powder over the top.

# Notes:

01 - Making the three cake layers separately ensures they turn out more even.
