1/3cupgranulated sugar (for the egg yolk soft crust)
1tbspvanilla extract
1/2cupground walnuts
1/2cupshaved chocolate
Whipped cream or vanilla ice cream (optional)
Instructions
Preheat oven to 350F.
Put butter, cocoa, flour and sugar in a bowl and mix until well combined. In a separate bowl, beat the egg whites until stiff and fluffy. Put the beaten egg whites in the bowl with the cocoa mixture. Mix well in circular motions using a spatula. Add ground walnuts and vanilla. Continue mixing until well combined. Pour the mixture into a 8x8 baking pan lined with parchment paper. Place the pan in the preheated oven and bake for 40 minutes.
While the cake is baking, it's time to make the egg yolk "crust." Beat the egg yolks and sugar in a bowl until the sugar has dissolved and the mixture is smooth and velvety. Take the cake out of the oven and put it on a plain surface. Pour the egg yolk & sugar mixture on top of the cake. Put the cake back in the oven and bake for another 10 minutes or until the egg yolk crust has hardened/cooked.
Take the cake out of the oven and let it cool for about 30 minutes. Sprinkle shaved chocolate on top of the cake, then cut the cake as you wish. Serve the cake as it is or topped with whipped cream, creme anglaise or vanilla ice cream.
