Wash and scrub the apples (skin on). Cut in half and remove the core — do not quarter. Slice as thin as possible with a mandoline or knife.
Place slices in a bowl, add the lemon juice, and cover with just enough room-temperature water. Cover and microwave 1–2 minutes until pliable, then let cool. (Or soften in a pan with 1 tsp butter over low heat.)
Mix the brown sugar with 2 tsp of the cinnamon; set aside.
In a separate bowl, stir the softened cream cheese with the remaining 2 tsp cinnamon (and a spoonful of the cinnamon sugar to taste) until smooth.
On parchment, unfold the puff pastry and roll out slightly. Cut lengthwise into 6 even strips. Spread a thin layer of cream cheese over each strip.
Fan the apple slices along the top half of each strip, skins peeking over the edge, overlapping slightly. Leave a ⅓-inch bare gap at one end.
Fold the bottom of the pastry up over the apples and roll from one end to seal into a rose. Pinch the seam. Place in a parchment-lined muffin cup.
Air fry at 330°F for 12–15 minutes, checking at 10, until golden and puffed.
Cool a few minutes on a rack, dust with icing sugar and cinnamon, and serve warm.
