Ingredients You’ll Need

1 cup unsalted butter, melted: Essential for a rich flavor. If you’re out of unsalted, use salted butter but reduce the added salt.
½ cup granulated sugar: For sweetness in the crust and a bounce of flavor in the filling.
2 teaspoons vanilla extract: Adds depth and warmth to the bars. Choose pure vanilla for a more robust flavor.
2½ cups all-purpose flour: Provides the base for both the crust and crumb topping. You might try an all-purpose gluten-free blend if preferred.
¼ teaspoon salt: Balances sweetness and enhances flavor.
5 cups peaches (about 5–6 medium peaches), peeled and diced: They create the filling. Feel free to leave the peel on for added nutrients and texture!
⅓ cup light brown sugar: Offers a subtle caramel flavor to the peach filling.
2 tablespoons granulated sugar: To add to the peach mixture for extra sweetness.
2 tablespoons cornstarch: Helps thicken the peach filling, preventing it from becoming too runny.
1 teaspoon ground cinnamon: Adds a lovely warm flavor that complements the peaches.
1 teaspoon vanilla extract: Another splash to enhance the peach filling.
¾ cup old-fashioned oats: Gives the topping a hearty texture and chewiness.
¾ cup all-purpose flour: Used in the crumb mixture.
½ cup packed light brown sugar: Sweetens the crumble topping with its rich, molasses-like notes.
½ teaspoon ground cinnamon: For grounding flavor in the crumb topping as well.
¼ teaspoon sea salt: Again, to balance sweetness.
6 tablespoons unsalted butter, melted: Binds the crumb topping together.
1 cup powdered sugar: For a smooth, sweet glaze on top.
2 tablespoons milk: To thin the glaze to your desired consistency.
½ teaspoon vanilla extract: Adds flavor to the glaze for that perfect finish.

How to Make Peach Crumb Bars

Preheat the oven: Set it to 350°F (180°C). This ensures even baking.
Prepare the pan: Line a 9-inch square baking pan with parchment paper, leaving some overhang to make removal easier later.
Combine the crust ingredients: In a large bowl, stir together the melted butter, ½ cup granulated sugar, and 2 teaspoons vanilla extract until fully combined.
Add dry ingredients: Mix in 2½ cups all-purpose flour and ¼ teaspoon salt until a soft dough forms.
Press into the pan: Firmly press the dough evenly into the bottom of your prepared pan.
Bake the crust: Place in the preheated oven and bake for 15 minutes or until the edges just begin to turn lightly golden.
Prepare the peach filling: While the crust bakes, combine 5 cups diced peaches, ⅓ cup light brown sugar, 2 tablespoons granulated sugar, 2 tablespoons cornstarch, 1 teaspoon ground cinnamon, and 1 teaspoon vanilla extract in a large bowl.
Mix the peaches: Gently toss until the peaches are evenly coated with the sugar mixture. Spread this peach mixture evenly over the warm crust once it comes out of the oven.
Prepare the crumble topping: In a medium bowl, mix together ¾ cup old-fashioned oats, ¾ cup all-purpose flour, ½ cup packed light brown sugar, ½ teaspoon ground cinnamon, and ¼ teaspoon sea salt.
Add the butter: Pour in 6 tablespoons melted unsalted butter, stirring until large, crumbly clusters form.
Spread the topping: Sprinkle the crumble evenly over the peach layer, covering it completely.
Bake until golden: Return to oven and bake for another 30–35 minutes, or until the crumb topping is golden brown and the peach filling is bubbling around the edges.
Cool completely: Allow the bars to cool in the pan for at least 30 minutes before lifting them out with the parchment and cooling completely on a wire rack.
Make the glaze: Whisk together 1 cup powdered sugar, 2 tablespoons milk, and ½ teaspoon vanilla extract gradually. Add more milk for a drizzle consistency.
Drizzle and serve: Drizzle the glaze over the cooled bars and slice into squares.

Storing & Reheating

To keep your Peach Crumb Bars fresh, store them in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate them for up to a week. You can also freeze these bars for up to 3 months. Just wrap them tightly in plastic wrap and place them in a freezer-safe container. When it’s time to enjoy them, simply thaw at room temperature or reheat in a 350°F (180°C) oven for about 10-15 minutes. Note that the texture may soften slightly, but they’ll taste just as fabulous!

Chef’s Helpful Tips

If your peaches are not quite ripe, try to let them sit out at room temperature for a day or two to develop sweetness.
Be gentle when mixing the peach filling to prevent mashing the fruit too much.
Allow ample cooling time; this will help the bars set up nicely and maintain their shape when cutting.
If you want to boost the flavor, feel free to add a squeeze of lemon juice to the peach filling for brightness.
Don’t hesitate to mix in other fruits like blueberries or strawberries for a fun twist!

Peach Crumb Bars are not only a luscious treat, but they’re also a canvas for your creativity. With their rich flavors and delightful textures, they’re perfect for any occasion. Change the fruit, try different glazes, or just enjoy them as they are—the possibilities are endless! Give them a try, and soon you may find they become your go-to dessert.

Recipe FAQs

Can I use frozen peaches for this recipe?

Absolutely! If using frozen peaches, make sure to thaw them first and drain excess liquid before mixing them into the filling. This helps achieve the right texture and prevents a soggy crust.

How can I make these bars gluten-free?

You can easily substitute the all-purpose flour with a gluten-free blend that measures cup-for-cup. Also, check that any oats used are certified gluten-free.

Can I make these Peach Crumb Bars ahead of time?

Yes, they keep well for several days at room temperature or in the fridge. You can bake them a day in advance and keep them covered until you’re ready to serve!
