Preheat your oven to 350°F and spray a muffin tin with nonstick spray.
Wash and core your apples, then slice them super thin—I like to keep the red skin on for that pretty rose-petal look.
Toss the slices into a bowl with the juice of half a lemon, a teaspoon or two of sugar, and a pinch of cinnamon.
Unfold the puff pastry sheets and brush them with your melted butter. Sprinkle the remaining sugar and cinnamon mixture generously over the buttered side.
Now, cut each sheet into 6 long strips (you’ll end up with 12 total).
Take one strip of puff pastry and arrange a few apple slices along the top half, letting the red peel peek out over the edge.
Fold the bottom half of the pastry strip up over the apples (kind of like tucking them in). Then, gently roll the strip into a spiral! Place it in the muffin tray, and repeat for the rest of the strips.
Pop your tray in the oven and bake for 25-30 minutes until the roses are golden and the pastry is puffed and flaky.
Once the apple roses are out of the oven, let them cool for about 10 minutes.
Serve and Enjoy! Dust them with powdered sugar to make them look extra pretty.
