Preheat oven to 400F/200C.
Cut the puff pastry into 6 rectangles and set aside.
Lay a sheet of parchment paper on a baking tray, and drizzle honey into 6 rectangles just slightly smaller than the puff pastry sheets. Divide the brown sugar, butter and cinnamon if using across the 6 rectangles.
Lay 6 apples slices onto each rectangle, making sure that the apples are overlapping so the skin is not showing.
Cover each rectangle with a piece of puff pastry and gently press down to adhere to the apples.
Brush with the egg wash, then bake for 15-20 minutes until golden brown.
Let cool briefly then enjoy as is or with vanilla ice cream and enjoy!
