Knead the flour, half of the sugar, 1 egg, 150 g butter and the baking powder and chill for 30 minutes.
Then put in a greased springform pan and press flat, also pull up one edge.
Peel the boskopp and cut out with the apple cutter and place on the bottom of the springform pan.
Bring 2 cups of cream to the boil and use the 3rd cup to mix the pudding powder (including the rest of the sugar and vanilla sugar). Boil the pudding and immediately pour it over the apples.
Bake at 175 degrees on the lowest rack for about 70 minutes. Can be sprinkled with cinnamon and sugar. Then chill for 24 hours.
Tip: After the apples have been cut out, you can stuff marzipan and / or raisins soaked in rum into the opening.
