- 1/3 cup granulated sugar (67 grams): Adds just the right amount of sweetness to the crust.
- 1/3 cup light brown sugar, lightly packed (67 grams): Enhances the flavor profile beautifully with its molasses notes.
- 3/4 teaspoon baking powder: Helps the crust rise and adds lightness.
- 1/2 teaspoon kosher salt: Balances the sweetness and enhances the flavors.
- 3/4 cup unsalted butter, cut into tablespoon-size pieces (170 grams): The star ingredient that brings richness and flavor.
- 4 medium peaches, pits removed (about 1.4 pounds): Choose ripe but firm peaches for the best texture and flavor.
- 1/2 cup light brown sugar, lightly packed (105 grams): For the filling, this adds a delightful sweetness.
- 1/4 teaspoon ground cinnamon: A warm spice that complements the peaches perfectly.
- 2 teaspoons vanilla extract: Adds depth and enhances the overall flavor.
- 1 teaspoon corn starch: Helps thicken the peach filling.
- A pinch of kosher salt: Just a touch to bring all the flavors together.
Step-by-Step Instructions
Now that we have our ingredients ready, let’s dive into the process of making these delightful bars:
- Preheat your oven to 350°F (175°C). Grease a 9-inch square baking dish and line it with parchment paper for easy removal.
- In a small saucepan, melt the butter over medium-low heat. Watch closely as it begins to bubble and pop. Stir occasionally until it foams and develops dark brown flecks, indicating it’s perfectly browned. Remove from heat and let cool slightly.
- Slice each peach into 8 segments and then into half-inch pieces.
- In a small mixing bowl, combine the peach slices, brown sugar, cinnamon, vanilla extract, corn starch, and a pinch of salt. Toss to combine.
- In a medium mixing bowl, whisk together the all-purpose flour, granulated sugar, light brown sugar, baking powder, and salt, ensuring there are no lumps.
- Pour the browned butter into the dry ingredients. Gently mix them together with a rubber spatula until they form a crumbly dough.
- Press about 1/2 to 2/3 of the crumble mixture into the bottom of the prepared baking dish, creating an even layer.
- Pour the peach mixture over the crust and spread it evenly.
- Crumble the remaining topping over the peaches.
- Bake on the middle rack for 50-60 minutes, or until the topping is golden brown and the filling is bubbling.
- Allow to cool completely on a wire rack, then chill in the fridge for about an hour.
- Run a knife along the edges to loosen the bars. Lift them out using the parchment paper and transfer them to a cutting board. Cut into 16 squares and serve.
Expert Tips for the Best Peach Bars

To ensure your peach bars turn out perfectly every time, keep these tips in mind:
- Use ripe peaches: The best flavor comes from peaches that are ripe but still firm, ensuring they hold their shape during baking.
- Don’t skip browning the butter: This step adds a depth of flavor that elevates your bars from good to unforgettable.
- Chill before cutting: Allowing the bars to chill in the fridge helps them set properly, making them easier to slice.
- Experiment with spices: Consider adding nutmeg or cardamom for a different flavor profile.
- Make ahead: These bars can be made a day in advance, allowing the flavors to meld beautifully.
- Try different fruits: While peaches are wonderful, feel free to swap in other fruits like nectarines or plums for a unique twist.
- Adjust sweetness: Depending on the sweetness of your peaches, you may want to adjust the sugar in the filling.
- Store properly: Keep any leftovers in an airtight container in the fridge for up to a week.
Common Mistakes and Troubleshooting
Even the best of us can run into a few hiccups. Here are some common mistakes and how to avoid them:
- Overmixing the dough: Gently mix the ingredients to avoid tough bars; a little lumpiness is okay.
- Underbaking: Make sure the topping is golden brown and the filling is bubbling to ensure they are fully cooked.
- Using too much filling: Stick to the recommended amounts to avoid a soggy crust.
- Not allowing to cool: Patience is key; letting them cool fully ensures better slicing.
Storage and Make-Ahead Instructions
These bars are perfect for planning ahead. Here’s how to store them:
- Room temperature: They can be kept at room temperature for a day but are best refrigerated.
- Refrigerator: Store in an airtight container for up to a week.
