Press cookie dough down into the tart pan and up along the sides of the pan.
Bake for 8-10 minutes, or until cookie crust is lightly browned. Remove from oven and place on a cooling rack.
Using a stand or hand held mixer, beat cream cheese until smooth. Add powdered sugar and vanilla extract and mix until well combined. Spread over the top of the cookie layer.
Cut peach into slices, arranging them around the tart.
Notes
Makes 8-10 servings. A single peach sliced onto the tart makes a pretty presentation, but if you've got lots of peaches on hand? Feel free to layer on more!
