Creating your own Peaches and Cream Crumble Bars is easy with these straightforward steps:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Prepare an 8×8 inch baking pan by greasing it or lining it with parchment paper for easy removal.

2. Make the Crust and Crumble Topping:
– In a large mixing bowl, combine the flour, rolled oats, brown sugar, granulated sugar, baking powder, salt, and cinnamon.
– Pour in the melted butter and stir until the mixture is crumbly and well combined.

3. Prepare the Peach Filling:
– In another bowl, mix the sliced peaches with lemon juice, cornstarch, granulated sugar, and vanilla extract. Make sure the peaches are evenly coated.

4. Prepare the Cream Layer:
– In a medium bowl, beat the softened cream cheese with powdered sugar and vanilla extract until smooth. Gently fold in the whipped cream until well combined.

5. Assemble the Bars:
– Press half of the crust mixture firmly into the bottom of the prepared baking pan as a base layer.
– Spread the peach filling evenly over the crust.
– Spoon the cream layer over the peach filling, spreading it gently to cover.
– Sprinkle the remaining crumble topping on top of the cream layer.

6. Bake: Place the assembled bars in the preheated oven and bake for 40-50 minutes or until the top is golden brown and the filling is bubbling.

7. Cool: Once baked, remove the bars from the oven and let them cool in the pan for at least 1 hour. After they have cooled, transfer them to the refrigerator for an additional 1-2 hours to set.

8. Cut and Serve: Once fully chilled, carefully cut the bars into squares and serve.
