Wash the apples, cut them in half and remove the core. Slice into thin slices, the slices must be flexible.
Roll out the puff pastry on the work surface. Cut a roll from the long side into 6 strips of equal width and spread thinly with the jam. Cover the upper half of the strip with apple slices, so that the red peel protrudes over the strip like an arch. Arrange the apples overlapping like a roof tile.
Mix the cinnamon and sugar and sprinkle with the apples.
Fold the bottom half of the puff pastry over the apples so that only the top arches peek out and roll up the strip to form a rose. Proceed in the same way with all strips of dough.
If necessary, grease the muffin molds and place the puff pastry roses in the mold.
Bake in the oven for about 20 minutes until the pastries are lightly golden brown. Dust with powdered sugar.
