How to Make Peach Crumb Bars
Preheat the Oven: Set your oven to 350°F (180°C) and prepare a 9-inch square baking pan by lining it with parchment paper, leaving an overhang on two sides for easy removal.
Make the Dough: In a large mixing bowl, combine 1 cup melted unsalted butter, ½ cup granulated sugar, and 2 teaspoons vanilla extract until mixed well. Add 2½ cups all-purpose flour and ¼ teaspoon salt, stirring until a soft dough forms.
Press the Dough: Transfer the dough into the prepared baking pan, pressing it evenly across the bottom. Bake for 15 minutes, or until the edges start turning lightly golden.
Prepare the Peach Filling: While the crust is baking, mix 5 cups diced peaches, â…“ cup light brown sugar, 2 tablespoons granulated sugar, 2 tablespoons cornstarch, 1 teaspoon ground cinnamon, and 1 teaspoon vanilla extract in a large bowl. Gently mix to coat the peaches.
Layer the Peaches: After baking, spread the peach mixture evenly over the warm crust in the pan.
Make the Crumble Topping: In another bowl, stir 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. Pour in 6 tablespoons melted unsalted butter, mixing until you form large, crumbly clusters.
Add the Crumble Topping: Evenly sprinkle the crumble mixture over the peach layer.
Bake Again: Bake the entire assembly for an additional 30-35 minutes, or until the topping turns golden brown and the peach filling bubbles around the edges.
Cool Completely: Let the bars cool in the pan completely. Using the parchment paper overhang, lift the bars out before slicing into squares.
Prepare the Drizzle: In a small bowl, whisk together 1 cup powdered sugar, 2 tablespoons milk, and ½ teaspoon vanilla extract until smooth. Add extra milk, as needed, for a drizzle consistency.
Drizzle and Serve: Drizzle the prepared icing over the cooled bars before slicing them into squares and serving.
Storing & Reheating
Store your Peach Crumb Bars at room temperature in an airtight container for up to three days. For longer freshness, refrigerate them in a sealed container for up to a week. If you want to freeze them, wrap the bars tightly and store them in the freezer for up to three months. To reheat, slice them into squares and warm them in the oven at 350°F for about 5-10 minutes to refresh their texture and flavor.
Chef’s Helpful Tips
- Ensure your butter is completely melted but not hot when mixing into your dough to prevent it from cooking the flour.
- Use ripe peaches for the best flavor; firm peaches will not develop as much sweetness when baked.
- If your crumble topping doesn’t clump together, you may need to add a bit more melted butter until desired texture is reached.
- You can add nuts or coconut to your crumble for additional texture if desired.
- These bars are excellent for make-ahead options; they taste even better the day after baking!
You’ll find these Peach Crumb Bars to be not only a delicious treat but also incredibly simple to whip up for any occasion. The combination of crumbles and sweet peaches creates a perfect blend you won’t want to put down.

Recipe FAQs
Can I use frozen peaches for this recipe?
Absolutely! Frozen peaches work well if you can let them thaw and drain excess moisture before using. They might not hold their shape as well, but they will still taste great in the bars.
Can I substitute the brown sugar with something else?
Yes! If you prefer, you can swap out the brown sugar with coconut sugar for a healthier alternative, or you can use more granulated sugar, although this might change the flavor slightly.
What should I do if my filling is too runny?
If your peach filling seems overly liquidy, you may have used extra juicy peaches. Just add a bit more cornstarch, about a tablespoon, while mixing the peaches before layering them on the crust.
Could I make these Peach Crumb Bars gluten-free?
Definitely! Use a gluten-free all-purpose flour blend for the crust and crumble, and ensure all ingredients such as oats are certified gluten-free.
