Roll out the puff pastry on a lightly floured surface to smooth and thin it slightly. Cut out circles about 4 inches in diameter.
Place the pastry circles onto a baking sheet lined with parchment paper. Use a fork to poke small holes in the center of each circle, leaving a border of about ½ inch around the edge.
In a mixing bowl, beat the softened cream cheese until smooth. Add the powdered sugar and vanilla extract, mixing until combined and creamy.
Spread a layer of the cream cheese mixture over each pastry circle, keeping the border clear for rising.
Arrange the thinly sliced peaches on top of the cream cheese layer. In a small bowl, mix the honey and cinnamon, then drizzle it over the peaches.
Beat the egg in a small bowl. Brush the edges of the pastry with the egg wash to achieve a golden brown color when baked.
Bake in the preheated oven for 15-18 minutes, or until the pastry is puffed and golden.
