Thaw the puff pastry sheets side by side (approx. 20 minutes), then stack them on top of each other and roll them out on the floured work surface to a thickness of about 4 mm.
Line the bottom of the 26 cm springform pan with baking paper. Cut the dough sheets to round and place them on top, pulling up a very small edge with your fingers.
Brush the dough evenly with the apple jelly. Peel and quarter the tart apples, remove the core and cut the quarters again into 5-6 evenly narrow wedges and immediately turn them in lemon juice. Then lay out the apple slices on the dough base like a roof tile from the outside in. Work evenly!
Spread the sugar, butter in flakes and cinnamon on the apples. Bake the cake in the oven preheated to 220 ° for about 35 minutes. The base should be crispy and the apples should be soft and shiny golden brown.
