Unroll the Today® Original Puff Pastry and cut into 6 equal squares. Divide the apple onto the middle of each square, sprinkle over cinnamon and drizzle with honey.
Brush one edge of each square with egg and fold over the opposite edge to make a parcel.
Place the squares fold-side down on a lined baking tray.
Brush with egg and bake for 20 minutes.
Remove from the oven and set aside to cool. Mix the icing sugar and water and drizzle over the Danishes.
