Peel, halve and core apples. Sprinkle with lemon juice. Whisk the fat, sugar, vanilla sugar and aroma with the whisk of the hand mixer until white-creamy. Stir in the eggs one after the other.
Mix flour and baking powder and stir in. Fill the dough into a greased and flour-dusted springform pan (30 x 30 cm) and smooth it down. Spread the apples evenly on the dough with the opening facing upwards and press down lightly.
Put a teaspoon of cranberry jam in each apple opening. Spoon the rest of the jam onto the dough between the apples. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 2) for approx. 45 minutes.
Bring apricot jam to the boil in a small pot with 1 tablespoon of water. Pass through a sieve. Spread the apples immediately after baking. Let it cool down on a cake rack. Remove the cake from the tin.
Dust with icing sugar. Whipped cream tastes good with it.
