Creating the stunning Walnut Blitz Torte involves a series of straightforward steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease and flour three 8-inch round cake pans.
2. Prepare Walnuts: Finely chop the walnuts and set aside.
3. Separate Eggs: In a large bowl, separate the egg whites from the yolks.
4. Whip Egg Yolks: In another bowl, beat the egg yolks and granulated sugar until the mixture is pale and creamy.
5. Add Ingredients: Stir in the flour, baking powder, vanilla extract, and finely chopped walnuts into the yolk mixture until combined.
6. Whip Egg Whites: In a separate bowl, beat the egg whites until stiff peaks form.
7. Combine Mixtures: Gently fold the egg whites into the walnut mixture, being careful not to deflate the air.
8. Divide Batter: Pour the batter evenly into the prepared cake pans.
9. Bake: Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
10. Cool: Remove from the oven and allow the cakes to cool in their pans for 10 minutes. Then transfer them to wire racks to cool completely.
11. Prepare Whipped Cream: While the cakes cool, whip the heavy cream with powdered sugar until soft peaks form.
12. Assemble Torte: Place one layer on a serving platter, spread some whipped cream on top, then add a second layer followed by more cream, and finally add the third layer on top.
13. Top and Garnish: Spread the remaining whipped cream over the top of the torte and garnish with additional walnuts, if desired.
14. Chill and Serve: Refrigerate for at least 30 minutes before slicing and serving.
