  Preheat the oven to 160 °C. Line a baking tray with baking paper.

  Spread the batter onto the prepared tray, leveling the surface with a spatula to the edges. Place the tray in the preheated oven and bake for 30–35 minutes.

  Remove the tray from the oven and, while the cake base is still warm, pour the glaze over it. Let it cool completely. The next day, cut the cake into cubes or rectangles.

  For the glaze: Cream the egg yolks with the powdered sugar, vanilla sugar, and rum until you get a creamy and light-colored mixture. Pour the glaze over the warm cake base immediately after removing it from the oven.

  Tip: You can use a mix of walnuts and hazelnuts for a more complex flavor, but classic walnuts offer the best traditional taste.
