Prep
- Preheat the oven to 350°F (175°C). Set out a 9×13-inch baking pan and parchment paper for lining.
- Line a 9×13-inch baking pan with parchment paper. Leave some overhang so the bars lift out easily.
Make the crust
- Mix the graham cracker crumbs, granulated sugar, cinnamon, and melted butter until evenly combined. The mixture should look like damp sand.
- Firmly press the crust mixture into the prepared pan. Use the bottom of a measuring cup to pack it tightly.
- Bake for 8 minutes, then let cool. The crust should look lightly set and fragrant.
Make the cheesecake filling
- Beat the cream cheese until smooth. Scrape the bowl so there are no lumps.
- Add the granulated sugar and mix well. Continue mixing until the mixture looks glossy and smooth.
- Beat in the eggs one at a time. Mix just until each egg is incorporated.
- Mix in the vanilla extract and sour cream. Stop once the batter is uniform.
- Spread the cheesecake filling evenly over the crust. Smooth the top into an even layer.
Make the peach layer
- Toss the peaches with brown sugar, cornstarch, cinnamon, and lemon juice. Coat evenly so every peach piece is glossy.
- Spoon the peach mixture evenly over the cheesecake. Distribute to the edges without pushing the filling off-level.
- Gently swirl the top slightly if desired. Use a toothpick or knife tip for a marbled effect.
Bake and chill
- Bake for 38–45 minutes until the center is just set. The middle should have a slight jiggle but not slosh.
- Cool completely at room temperature. This prevents condensation and helps the bars slice cleanly.
- Refrigerate for at least 4 hours before slicing. Chill until fully firm.
- Garnish with whipped cream and fresh peach slices before serving. Finish with a light sprinkle of graham cracker crumbs if desired.
Notes
Pro tip: soften the cream cheese fully before beating so the filling stays smooth; if it’s still cool, lumps can form. Store covered in the refrigerator up to 4 days. Freezing: yes, freeze individual bars in an airtight container for up to 2 months, thaw overnight in the fridge. For a lighter option, use low-fat cream cheese and light sour cream while keeping the same baking time.
