Ingredients You Will Need

To make these delicious bars, you will need to gather a few simple kitchen staples divided into three easy parts for the crust, the cream cheese filling, and the peach crumble topping.

For the Crust and Crumble Topping

• 2 cups all purpose flour

• 1 cup rolled oats

• 1 cup brown sugar, packed

• 1 teaspoon baking powder

• 0.5 teaspoon salt

• 1 teaspoon ground cinnamon

• 0.75 cup unsalted butter, melted and cooled

• 0.5 cup sourdough discard, unfed and at room temperature

• 1 teaspoon pure vanilla extract

For the Cream Cheese Layer

• 16 ounces cream cheese, softened at room temperature

• 0.5 cup granulated white sugar

• 1 large egg, at room temperature

• 1 teaspoon pure vanilla extract

• 1 tablespoon fresh lemon juice

For the Fresh Peach Layer

• 3 cups fresh peaches, washed, peeled, and diced into small cubes

• 2 tablespoons granulated white sugar

• 1 tablespoon cornstarch

• 0.5 teaspoon ground cinnamon

Step by Step Method

Step 1: Prepare Your Kitchen and Baking Pan

Start by heating your oven to 350 degrees Fahrenheit so it reaches the right temperature while you prepare the ingredients. Take an eight inch or nine inch square baking pan and line it carefully with parchment paper, leaving a little extra paper hanging over the sides so you can easily lift the finished bars out later. Lightly grease the paper with a tiny bit of butter or baking spray to make sure nothing sticks.

Step 2: Make the Crust and Crumble Mixture

In a large mixing bowl, combine the all purpose flour, rolled oats, packed brown sugar, baking powder, salt, and ground cinnamon. Stir these dry ingredients together using a whisk until everything is evenly mixed without any big lumps of sugar. Next, pour in the melted butter, room temperature sourdough discard, and vanilla extract. Use a fork or your clean hands to mix everything together until it forms a thick, pebbly, crumbly dough.

Step 3: Press the Bottom Crust

Take about two thirds of the crumble dough you just made and press it firmly into the bottom of your prepared baking pan. Make sure you press it down evenly into all four corners using the flat bottom of a measuring cup or your fingers to form a solid, flat crust base. Keep the remaining one third of the crumble dough in the bowl and set it aside for later to use as your top layer.

Step 4: Bake the Crust Base

Place the pan with the bottom crust into your preheated oven and bake it for about twelve to fifteen minutes. You want the base to look slightly set and golden around the edges, which helps it stay crispy under the heavy cheesecake filling. Once the time is up, carefully remove the pan from the oven and set it on a wire rack while you prepare the creamy filling.

Step 5: Beat the Cheesecake Filling

In a medium mixing bowl, add the softened cream cheese and white sugar. Use an electric hand mixer or a stand mixer set to medium speed to beat them together for about two minutes until the mixture looks completely smooth, creamy, and fluffy. Add the room temperature egg, vanilla extract, and fresh lemon juice to the bowl. Beat again on low speed just until everything is combined and smooth, taking care not to overmix the batter once the egg is inside.

Step 6: Mix the Peach Layer

In a separate small bowl, toss your diced peaches together with the two tablespoons of white sugar, cornstarch, and ground cinnamon. Stir gently with a spoon so every piece of peach is coated evenly. The cornstarch is very important here because it thickens up the juicy fruit liquids as it bakes, preventing your bars from becoming soggy.

Step 7: Assemble All the Layers

Pour the smooth cream cheese mixture over your partially baked warm crust, using a spatula to spread it out into an even layer from edge to edge. Next, gently spoon the cinnamon peach mixture over the top of the cream cheese, distributing the fruit evenly across the pan. Finally, take your saved crumble dough and sprinkle it evenly over the peaches using your fingers to create small and medium clusters.

Step 8: Bake to Golden Perfection

Place the assembled pan back into the oven and bake for thirty five to forty five minutes. You will know the bars are fully baked when the crumble on top looks beautifully golden brown and the cheesecake center is set with only a very slight wobble in the middle when you gently shake the pan.

Step 9: Cool and Chill

Remove the pan from the oven and let it cool completely down to room temperature on a wire rack, which usually takes about one hour. Once cooled, place the entire pan into the refrigerator for at least three to four hours, or preferably overnight. Chilling is crucial because it allows the cheesecake layer to fully set so you can slice the bars into neat, clean squares.

Step 10: Slice and Serve

Lift the chilled slab out of the pan using the parchment paper handles you created earlier. Place it on a cutting board and use a large sharp knife to cut it into sixteen neat square bars. Wipe the knife clean with a damp warm cloth between each cut to keep the edges looking perfect. Serve cold or at cool room temperature and enjoy every delicious bite.

Why This Recipe Is Special

This dessert is truly special because it blends different baking arts into one seamless, crowd pleasing treat that satisfies every craving. The addition of sourdough discard is the real secret star of the show. Sourdough discard adds a delicate tangy flavor profile that cuts through the rich fat of the butter and cream cheese, bringing a subtle depth that standard flour and sugar bases simply cannot match. It also helps create a wonderful crumb texture in the crust, keeping it crisp yet tender without becoming overly dense or dry.

From a health and lifestyle perspective, making your own baked goods at home allows you to take total control over what goes into your body. Fresh peaches bring natural fiber, vitamin C, potassium, and antioxidants to every serving. Rolled oats add whole grain goodness, providing heart healthy fiber that keeps your digestion happy and gives you longer lasting energy. Furthermore, using leftover sourdough discard is a brilliant way to cut down on food waste in your household, allowing you to turn simple leftover flour and water into a nourishing homemade feast for your family.

The incredible balance of textures is another reason why this recipe stands far above average baked treats. You get four distinct experiences in one bite: the crunchy oat base, the melt in your mouth cream cheese, the sweet soft cooked fruit, and the crisp brown sugar topping. It satisfies both light summer fruit dessert cravings and cozy rich autumn bakery cravings, making it a versatile recipe you can make and enjoy all year round.

Extra Tips for Better Taste

• Always use full fat brick cream cheese for the absolute best rich texture, as low fat versions contain higher water content that can make your cheesecake layer runny or soft.

• Make sure your cream cheese and egg are completely at room temperature before mixing so you get a totally smooth batter without any stubborn tiny lumps.

• If fresh peaches are out of season, feel free to use frozen diced peaches or even high quality canned peaches, making sure to drain off all liquid thoroughly and pat them dry with paper towels before tossing with cornstarch.

• Add a sprinkle of fresh lemon zest into the cream cheese batter to give the cheesecake a bright, citrusy lift that pairs amazingly well with the sweet peaches.

• Try tossing half a cup of chopped walnuts or pecans into the top crumble mixture if you want an extra layer of nutty crunch and rich healthy fats.

• Brown the butter in a saucepan first before mixing it into the dry crumble ingredients to give your entire crust a deep, warm, caramel like flavor profile.

• Cut your fresh peaches into small, even bite sized cubes so every single bar gets a balanced amount of fruit and cuts cleanly without dragging big fruit pieces through the cheese layer.

• Store your finished sliced bars in a single layer inside an airtight container in the refrigerator, where they will stay fresh and delicious for up to five full days.
