Wrap the edge and base of a springform pan (26 cm Ø) tightly with aluminium foil to prevent any liquid from leaking. Grease the mould.
Peel, quarter, core and cut apples into slices. For the dough, whisk eggs and sugar with the whisk of the mixer for about 5 minutes until creamy. Stir in milk. Sift the starch on top and stir in well so that no lumps are visible.
Preheat oven (electric cooker: 180 °C/circulating air: 160 °C/gas: see manufacturer). Pour some dough on the bottom of the mould. Place a part of the apples fan-shaped close together. Again spread some dough on top. Process the rest of the apples and dough in the same way.
Bake the apple pancake in a hot oven for about 70 minutes. Mix 1 tbsp. brown sugar and 1 tsp. cinnamon. Sprinkle the pancakes with cinnamon sugar halfway through the baking time. If necessary, cover the pancake with aluminium foil about 20 minutes before the end of the baking time.
Remove from the oven and leave to rest on a cake rack for about 30 minutes. Carefully remove from the mould and arrange on a cake plate dusted with icing sugar. Tastes best warm with vanilla ice cream or whipped cream.
