Additional Tips for Making this Recipe Better
Having made these bars countless times, I’ve picked up a few tricks to ensure they turn out perfectly every time.
- Don’t Overmix the Crust: When cutting the butter into the flour, stop when the mixture looks like coarse crumbs. Overmixing can develop the gluten in the flour, resulting in a tough crust instead of a tender, crumbly one.
- Use Ripe but Firm Peaches: For the best flavor, use peaches that are ripe and sweet, but still firm to the touch. Overly ripe or mushy peaches will release too much water and can make the bars soggy.
- Let the Bars Cool Completely: I cannot stress this enough! Patience is key. Letting the bars cool for at least 2-3 hours (or even chilling them in the fridge) allows the filling to set, making them easy to slice into neat squares.
Variations to Try
One of the best things about this recipe is how easily you can adapt it to your preferences or dietary needs. It’s a great base for your creative dessert ideas.
- Go Gluten-Free: Substitute the all-purpose flour with a 1-to-1 gluten-free baking flour blend. Ensure your rolled oats are certified gluten-free as well.
- Try Different Fruits: This recipe works beautifully with other stone fruits like nectarines, plums, or apricots. In the fall, try it with apples and an extra dash of cinnamon.
- Add Nuts for Crunch: For extra texture, add about a half cup of chopped pecans or walnuts to the oat topping mixture.
- Dairy-Free Option: Use a plant-based butter substitute in place of regular butter to make these bars dairy-free.

More Recipe Details
The beauty of this dessert lies in its simplicity and reliance on the natural sweetness of summer fruit. Don’t be tempted to use canned or frozen peaches; the texture and flavor of fresh peaches are essential for achieving that “heavenly” quality.
When peeling the peaches, you can blanch them in boiling water for 30 seconds to make the skins slip off easily. This recipe is forgiving, so don’t worry if your layers aren’t perfect.

Heavenly Summer Peach Bars Recipe
Ingredients
Method
- First, preheat your oven to 350°F (175°C). To make removing the bars easy later on, line a 9×13-inch baking pan with parchment paper. Leave some paper hanging over the sides to use as handles for lifting the bars out once they have cooled completely.
- In a large bowl, whisk together the flour, baking powder, salt, granulated sugar, and brown sugar. Add the cold, cubed butter to the dry ingredients. Using a pastry blender or your fingertips, cut the butter into the mixture until it resembles coarse crumbs with some pea-sized pieces remaining.
- Take out 1 ½ cups of the crumb mixture and set it aside for the topping. Press the rest of the mixture firmly and evenly into the bottom of your prepared baking pan. This will form the sturdy base for your peach bars. Bake it for 12 minutes to par-bake the crust.
- While the crust is in the oven, prepare the delicious peach filling. In a separate bowl, gently toss the sliced peaches with the cornstarch, sugar, lemon juice, cinnamon, and optional ginger. Let this mixture sit for about five minutes to allow the juices to release and the flavors to meld.
- Remove the partially baked crust from the oven. Carefully spread the peach mixture in an even layer over the warm crust, making sure to include all the delicious juices. Now, take the reserved crumb mixture, stir in the rolled oats, and sprinkle it evenly over the peaches.
- Return the pan to the oven and bake for an additional 30-35 minutes. You’ll know the bars are done when the oat topping is golden brown and the peach filling is bubbling around the edges. The aroma alone will tell you something wonderful is happening in your oven.
- Once baked, remove the pan and place it on a wire rack to cool completely. This step is crucial for clean slices. If you try to cut them while warm, they will fall apart. Once fully cooled, use the parchment paper handles to lift the entire block out of the pan and cut it into 12 bars.
