Ingredients You’ll Need

1 cup unsalted butter, melted: Provides richness and moisture; make sure it’s unsalted for better control over flavor.
½ cup granulated sugar: Balances the richness of the butter; you can use coconut sugar for a more caramel-like flavor.
2 teaspoons vanilla extract: Adds delicious depth; always use pure vanilla extract for the best taste.
2½ cups all-purpose flour: The foundation of the crust; you can substitute with gluten-free all-purpose flour.
¼ teaspoon salt: Enhances sweetness and balances flavors.
5 cups peaches (about 5–6 medium peaches): The star of the show; ripe, juicy peaches will yield the best results; you can leave the skin on for added texture.
⅓ cup light brown sugar: Adds a lovely caramel flavor to the peach filling.
2 tablespoons granulated sugar: Just a bit more sweetness for the filling.
2 tablespoons cornstarch: Thickens the peach mixture; arrowroot can substitute if needed.
1 teaspoon ground cinnamon: Offers warmth and spice; feel free to add a little nutmeg for a twist.
¾ cup old-fashioned oats: Adds texture to the crumb topping; quick oats can work, but the texture won’t be the same.
½ cup packed light brown sugar: Sweetens the crumble and adds chewiness.
½ teaspoon ground cinnamon: Complementing the oats for a delicious flavor.
¼ teaspoon sea salt: Balances the sweetness in the topping.
6 tablespoons unsalted butter, melted: Binds the crumble; always use unsalted, as mentioned before.
1 cup powdered sugar: For drizzling; you can use a sugar-free alternative here.
2 tablespoons milk: Helps in achieving the right consistency for the drizzle; plant-based milk will work too.
½ teaspoon vanilla extract: Adds extra flavor to the glaze.

How to Make Peach Crumb Bars

Preheat your oven: Set it to 350°F (180°C) and line a 9-inch square baking pan with parchment paper, allowing some overhang for easy removal later.
Make the crust: In a large bowl, blend together the melted butter, ½ cup granulated sugar, and 2 teaspoons vanilla extract until smooth. Gradually incorporate the 2½ cups all-purpose flour and ¼ teaspoon salt until a soft dough forms.
Press and bake the crust: Evenly press this dough into the bottom of your prepared pan. Bake it for about 15 minutes, just until the edges are lightly golden.
Prepare the peach filling: While the crust is baking, toss together the 5 cups diced peaches, ⅓ cup light brown sugar, 2 tablespoons granulated sugar, 2 tablespoons cornstarch, 1 teaspoon cinnamon, and 1 teaspoon vanilla extract in a bowl until the peaches are well coated.
Add the peach filling: Once the crust is out of the oven, spread the peach mixture evenly over it.
Make the crumb topping: In a medium bowl, combine the 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. Pour in the 6 tablespoons melted butter and mix until you see large, crumbly clusters.
Top and bake: Sprinkle the crumb topping evenly over the peach layer. Return to the oven and bake for 30–35 more minutes, or until the topping is golden brown and the filling is bubbling around the edges.
Cool completely: Allow the bars to cool in the pan completely before using the parchment overhang to lift them out.
Make the drizzle: Whisk together 1 cup powdered sugar, 2 tablespoons milk, and ½ teaspoon vanilla extract until smooth. Adjust with more milk if necessary to get a drizzle consistency.
Serve: Drizzle this sweet glaze over the cooled bars and slice into squares for serving.

Storing & Reheating

To store your Peach Crumb Bars, keep them at room temperature for up to three days, covered loosely with foil or in an airtight container. For longer storage, the bars can be refrigerated for up to a week. If you want to freeze them, wrap them tightly in plastic wrap or place in an airtight container, and they can last up to 3 months. When you’re ready to indulge again, simply reheat in the microwave for a few seconds or warm them in the oven at 350°F until they’re just warmed through. The texture is best enjoyed fresh, but they’ll still be delicious after thawing.

Chef’s Helpful Tips

Be sure to use ripe peaches for the best flavor; if they’re not in season, frozen peaches can also work—just thaw and drain excess moisture.
For a softer crust, avoid overmixing the dough; mix just until flour is incorporated.
When making the crumb topping, stir in the melted butter until you see big, crumbly clusters; don’t worry about it being perfectly mixed.
If you find your peach filling is too runny, increase the cornstarch by a tablespoon to help thicken it.
For an extra layer of flavor, consider stirring in a tablespoon of lemon juice into the peach mixture!

It’s hard to resist such an inviting dessert that effortlessly brings together the brightness of fresh fruit and rich buttery goodness. These Peach Crumb Bars offer the perfect way to savor summer flavors any time of the year. So why not give this recipe a try? You’ll be happy you did!

Recipe FAQs

Can I use canned or frozen peaches?

Yes! Canned or frozen peaches can be used; just make sure to drain canned peaches and thaw, then drain frozen peaches to prevent excess moisture in your filling.

How do I know when the bars are done baking?

The bars are ready when the topping is golden brown and the peach filling is bubbling around the edges. A toothpick inserted into the crumble should come out clean.

Can I make these bars ahead of time?

Absolutely! You can bake them a day in advance. Simply store them tightly covered at room temperature and drizzle them with icing just before serving.

How can I customize the topping?

Feel free to add nuts like chopped pecans or walnuts to the crumb topping for extra texture. Coconut flakes also make a delicious addition, adding a hint of tropical flavor!
