01 - 500g all-purpose flour
02 - 200g powdered sugar

04 - 2 large eggs
05 - 1 tablespoon vanilla sugar (or mix 1 vanilla pod or 1 tablespoon vanilla extract with 18g sugar)
06 - Zest from half a lemon
07 - A pinch of salt

→ Apple Filling

08 - 1kg tart-sweet apples (like Granny Smith, Boskoop, or Braeburn), peeled, cored, quartered, and sliced into 2.5mm pieces
09 - 60g sugar
10 - 1 tablespoon vanilla sugar (or mix 1 vanilla pod or 1 tablespoon vanilla extract with 18g sugar)
11 - 50g raisins
12 - 1/8 teaspoon ground cinnamon
13 - 1 tablespoon rum

→ Nut Filling

14 - 30g sugar
15 - 1 tablespoon honey (such as acacia honey)
16 - 60ml milk (or apple juice)
17 - 150g finely ground nuts
18 - 1 tablespoon rum

→ Poppy Seed Filling

19 - 30g sugar
20 - 1 tablespoon honey (such as acacia honey)
21 - 60ml milk (or apple juice)
22 - 150g ground poppy seeds
23 - 1 tablespoon vanilla sugar (or mix 1 vanilla pod or 1 tablespoon vanilla extract with 18g sugar)
24 - Zest from 1 lemon
25 - 1 tablespoon rum

→ Plum Filling

26 - 6 tablespoons powidl or thick prune puree (blend 12 pitted prunes with a little water)

→ Glaze

27 - 1 large egg, room temperature
28 - 1 tablespoon water
29 - Powdered sugar for dusting

# Instructions:

01 - Combine the dry ingredients. Add diced butter, working it into the mixture with your fingertips until crumbly. Toss in the eggs, mixing just until it forms a dough. If sticky, sprinkle in a little flour. Let it chill for 45 minutes.
02 - Coat the apple slices with sugar, vanilla sugar, raisins, cinnamon, and rum. Let the mixture sit and soak up the flavors.
03 - Warm the milk, sugar, and honey until they dissolve. Remove from heat, stir in the ground nuts and rum, then leave to cool.
04 - Heat milk, honey, and sugar to dissolve. Take off the heat, mix in the poppy seeds, vanilla sugar, lemon zest, and rum. Set aside to cool.
05 - Set the oven to preheat to 190°C (standard heat).
06 - Roll the dough out to about 3mm thick. Use two-thirds of it to line the bottom and sides of a springform pan (20-23cm). Wrap the pan in foil to secure it. Bake it blind for 15 minutes.
07 - Spread a layer of poppy seed filling first, followed by the nut mixture. Add the soaked apples with their juices on top. Finish with the prune puree or powidl.
08 - Use the leftover dough to cut 1.3cm strips. Arrange these into a lattice pattern on top of the filling. Brush the lattice with beaten egg.
09 - Place on the middle rack and bake for 50 minutes. Once baked, let it fully cool on a wire rack—preferably overnight.
10 - Carefully remove the cake from the pan. Dust with powdered sugar just before serving it.

# Notes:

01 - Use fresh poppy seeds for the best taste—they can go rancid over time.
02 - Letting the cake rest overnight makes it taste even better.
