Knead a smooth dough from 350g flour, 175g sugar, a pinch of salt and 200g butter (cold in pieces) and an egg. Then chill this dough for 30 minutes.
Grease the oven`s drip pan and dust it with flour.
Peel, quarter and core apples and cut into wedges, drizzle with lemon juice.
Roll out the dough on the drip pan and push the edges up a little.
Mix 150g butter, 250g sugar, vanilla sugar until frothy, stir in cream cheese, quark, 4 eggs, the rest of the lemon juice and custard powder. Spread the mixture on the dough and place the apples tightly on top of it like a roof tile. Sprinkle on top with almond sticks.
Bake in the preheated oven (E 200 ° convection 175 °) for 50 minutes.
Heat the jam, strain it through a sieve and spread it on the apples 10 minutes before the end of the baking time.
The Boss Kitchen editorial staff oversees content review, fact-checking, and recipe verification across the site. Published articles pass through the editorial team before going live, ensuring ingredient lists, techniques, cooking times, and nutritional claims hold up in a home kitchen. The team coordinates contributions across the site writers, handles reader corrections, and maintains consistency in measurement conventions, safety guidance, and dietary labeling. Posts under this byline typically represent team-reviewed reference material, site announcements, or editorial roundups rather than individual-author features, and they are held to the same sourcing standards as bylined recipe and product coverage.
