Step 1: Preheat the Oven: Begin by preheating your oven to 350°F (175°C).
Step 2: Prepare the Crust: In a mixing bowl, combine graham cracker crumbs, melted butter, and sugar. Press this mixture into a greased 9×13 inch baking dish.
Step 3: Make the Cheesecake Filling: Beat the softened cream cheese and sugar together until smooth. Add in the eggs, one at a time, followed by vanilla extract and lemon juice.
Step 4: Assemble the Layers: Pour the cheesecake filling over the crust, then layer the sliced peaches on top.
Step 5: Prepare the Peach Cobbler Topping: Combine sugar and cinnamon with the biscuit mix. Gradually stir in milk until just combined. Spoon this over the peaches.
Step 6: Bake: Bake for 45 minutes, or until the topping is golden brown and a toothpick inserted in the center comes out clean. Check around 35 minutes to avoid overcooking.
Step 7: Cool and Serve: Allow to cool at room temperature and then refrigerate for at least an hour.
