Creating Peaches and Cream Cheesecake Bars involves simple yet delicious steps. Follow these instructions for a successful baking experience:

1. Preheat Oven: Preheat your oven to 325°F (163°C). Grease a 9×13-inch baking dish.
2. Make the Crust: In a bowl, mix graham cracker crumbs with melted butter. Stir until combined, and press firmly into the bottom of the prepared baking dish.
3. Bake the Crust: Bake the crust in preheated oven for 10 minutes. Remove and allow it to cool slightly.
4. Prepare the Filling: In a mixing bowl, beat the softened cream cheese until smooth. Gradually add granulated sugar, mixing until well combined.
5. Add Eggs and Vanilla: Beat in the eggs one at a time, ensuring each egg is fully incorporated. Stir in vanilla extract and sour cream until smooth.
6. Add Peaches: Gently fold in the sliced peaches until evenly distributed throughout the mixture.
7. Pour Filling: Pour the cream cheese mixture over the cooled crust, spreading it evenly.
8. Bake Cheesecake: Bake in the preheated oven for 35-45 minutes, or until the edges are set and the center still has a slight jiggle.
9. Cool and Set: Remove from the oven and let the cheesecake bars cool at room temperature for about 1 hour. Transfer to the refrigerator for at least 1 hour, preferably overnight.
10. Serve: Dust with powdered sugar before cutting into squares. Garnish with mint leaves if desired.
