Prepare a muffin tin with parchment caps.
Heat up the oven to 350F.
Prepare the apple slices and drizzle them with a few drops of lemon juice.
Place them on a flat plate and microwave them for 1 minute just to soften them a bit.
Roll out the dough to a thin sheet (don’t overdo it) so it doesn’t rip easily and cut it into 1-1 1/4” strips, either horizontally or vertically
Work with one strip of dough at a time. Spread a thin layer of jelly or jam on it.
Arrange the apple slices on top of the dough strip when the arch part of the apple slice is peaking by 1/2” beyond the dough strip, and each slice overlaps the next.
Work with both hands, one holds the apples from moving, and one lifts the dough and rolls it tightly like a rose. Make sure to keep the bottom of the flower aligned.
Place each rose in a muffin cup.
Sprinkle each rose with a pinch of cinnamon sugar.
Bake at 350F for 30 min.
Let cool on a cooking rack, remove paper cups, arrange on a platter and sprinkle with powdered sugar.
