Crumble the yeast into lukewarm milk, add a teaspoon of sugar and mix. Cover the starter and set aside for about 15 minutes to activate.
10 g fresh yeast, 1 teaspoon sugar, 160 ml milk
Meanwhile, pour flour into a large bowl, add eggs, the rest of the sugar, soft butter, and nutmeg (you can use cinnamon instead).
450 g wheat flour - all-purpose, 50 g sugar, 2 eggs, 50 g butter, 1 pinch nutmeg
Pour in the yeast starter and knead the dough.
Cover the bowl with the dough with a towel and set aside for about an hour to rise.
Briefly knead the risen dough again and spread it into the prepared baking pan (lined with baking paper). Stretch the dough over the entire surface - it will be quite thin.
Cover the pan with a towel and set aside for about 15 minutes.
Turn on the oven to 200 degrees Celsius - top-bottom heat mode.
Meanwhile, peel the apples, remove the core, and cut them into small cubes.
3 apples
Mix the egg with sour cream and brush over the top of the dough.
1 egg, 1 tablespoon sour cream
Place the apples on top.
Sprinkle the apples with brown sugar and a little cinnamon and almond flakes.
2 tablespoons brown sugar, cinnamon, 2 tablespoons almond flakes
Bake for 15 minutes, then reduce the temperature to 180 degrees Celsius and bake for another 15 minutes - until the cake is golden brown.
After baking, let it cool slightly and serve while still warm :)

If the apples are not very sweet, you can additionally drizzle the cake with a little icing. Just mix half a cup of powdered sugar with 1-3 tablespoons of milk. Add milk one tablespoon at a time and mix.
