    Serves: 18 

    • 6 eggs, separated
    • 1/8 teaspoon cream of tartar
    • 200g caster sugar
    • 1/2 teaspoon vanilla extract
    • 1/2 cup finely ground digestive biscuit crumbs

    Prep:25min  ›  Cook:25min  ›  Ready in:50min 

    1. In a large bowl, beat the egg whites with the cream of tartar until stiff. Gradually beat in 4 tablespoons of the sugar until the mixture is slightly glossy. Set aside.
    2. In another large bowl, beat the egg yolks. Gradually beat in the remaining sugar until the mixture is thick and pale. Beat in the vanilla.
    3. In another bowl, stir together the digestive biscuit crumbs, baking powder and salt. Beat into the egg yolk mixture. Stir in the walnuts and chocolate chips. Stir in about 1/3 of the egg whites to lighten the batter and then fold in the rest gently but thoroughly.
    4. Turn the cake mixture into a greased and floured 20x30cm baking tin. Bake the cake in a preheated 180 C / Gas 4 oven for 25 to 30 minutes, or until it tests done with a skewer. Let cool on a rack.

    Great recipe! It's really quick and easy to make and everyone loves it! Everyone's always asking me the recipe for this cake! I've even been told it tastes like Turtles!  -  06 Feb 2005  (Review from Allrecipes US | Canada)


    This is very eggy and flat. The flavor is good, but I would bake it in a smaller pan next time.  -  01 Apr 2013  (Review from Allrecipes US | Canada)


    These were just ok. I understand the other review that says that it was eggy. I would describe it as spungy, but not bad. I did bake in a smaller baking pan based on that other recommendation and I think that helped. Otherwise, I imagine it would turn out super thin.I really don't understand the other person who said they are like turtles. Turtles have a caramel component that this is definitely missing. This was just ok. Would not make again.  -  11 Dec 2017  (Review from Allrecipes US | Canada)
