Ingredients of the Easy Peach Crumb Bars
For the Crust and Crumble
- 2 1/2 cups all-purpose flour
- 3/4 cup granulated sugar
- 1/4 teaspoon salt
- 1 cup unsalted butter, softened and cubed
- 1 large egg
For the Peach Filling
- 4 cups fresh peaches, peeled and diced
- 1/2 cup granulated sugar
- 1 tablespoon cornstarch
- 1 teaspoon vanilla extract
- 1/2 teaspoon ground cinnamon

Equipment / Tools Needed
- 9×9 inch square baking pan
- Large mixing bowl
- Pastry blender or fork
- Paring knife
- Parchment paper
Step-by-Step Instructions
Step 1: Prepare the Oven and Pan
Preheat your oven to 350°F (175°C). Line your 9×9 inch baking pan with parchment paper, leaving a small overhang on the sides so you can easily lift the finished bars out later. This ensures a clean release and quick cleanup.
Step 2: Create the Dough
In a large bowl, whisk together the flour, sugar, and salt. Add the cubed softened butter. Use a pastry blender or your fingers to work the butter into the dry mixture until it transforms into large, coarse crumbs. Remove one cup of this mixture and set it aside to use for the topping. Mix the egg into the remaining dough until it is just combined and crumbly.
Step 3: Press the Base
Transfer the larger portion of the dough into your prepared baking pan. Using your fingertips, press it firmly and evenly across the bottom to create a solid crust. Bake this base for 10 minutes to ensure it maintains a nice texture beneath the fruit layer.
Step 4: Toss the Fruit
While the base is par-baking, combine the diced peaches, sugar, cornstarch, vanilla extract, and cinnamon in a medium mixing bowl. Toss the mixture gently until the peaches are well coated and look glossy. The cornstarch will help thicken the peach juices during the baking process.
Step 5: Assemble and Bake
Spread the peach mixture evenly over the par-baked crust. Sprinkle the reserved crumb mixture over the top, making sure to cover most of the fruit. Bake for 35 to 40 minutes, or until the topping is golden brown and the fruit filling appears bubbly and thick. Allow the bars to cool completely in the pan before slicing; this is essential for the structure of the bars.

Tips & Tricks
For the best flavor, use peaches that are just slightly soft to the touch. If your peaches are very juicy, add an extra half-teaspoon of cornstarch to prevent the crust from becoming overly soft. Allowing the bars to chill in the refrigerator for an hour before slicing will give you the cleanest, most professional-looking cuts.
Serving Suggestions
These bars are divine served warm during a family dinner, especially when topped with a dollop of whipped cream or a generous scoop of vanilla bean ice cream. They also make an excellent addition to a breakfast brunch table alongside fresh coffee or iced tea.
Variations / Substitutions
If you have plums or nectarines on hand, they work as a wonderful 1:1 substitute for peaches. For a nuttier texture, feel free to add half a cup of chopped pecans or slivered almonds to the crumb topping. You can also incorporate a pinch of ginger into the fruit mixture to add a subtle, spicy depth that complements the sweetness of the peaches.
Storage and Reheating
Store your leftover bars in an airtight container at room temperature for up to two days, or in the refrigerator for up to five days. If you prefer them warm, reheat individual squares in a microwave for 15 seconds or in a toaster oven until they feel slightly soft again.

FAQ
How can I make these ahead of time?
You can prepare the bars entirely the day before you plan to serve them. Store them in the baking pan covered with foil or transfer them to an airtight container after they have cooled completely.
Can I use frozen peaches for this recipe?
Yes, frozen peaches work well if you thaw them completely and pat them thoroughly with paper towels to remove excess moisture. Otherwise, the extra liquid may make your crust soggy.
Why did my bars fall apart when I sliced them?
Cutting the bars while they are still warm is the most likely cause. The fruit filling needs time to set as it cools, so let them rest for at least two hours before attempting to slice them into squares.
Can I replace the flour with gluten-free options?
A high-quality 1-to-1 gluten-free baking flour blend should work just fine in this recipe. Just be sure the blend contains xanthan gum to provide the necessary structure for the crumb topping.
