How To Make Peach Crumb Bars
Baking these bars is an absolute joy—think buttery crumbs, juicy peach filling, and a perfectly golden top. With a little prep and about an hour in your kitchen, you’ll be rewarded with bars that hold together beautifully yet melt in your mouth. Let’s break down each step so you feel confident tackling this recipe from start to finish.
1. Preheat your oven to 350°F and line an 8×8-inch pan with parchment paper, leaving an overhang for easy removal.
2. In a large bowl, combine flour, oats, granulated sugar, baking powder, and salt until evenly mixed.
3. Cut cold butter into small cubes and use a pastry cutter or your fingertips to blend into the dry ingredients until a coarse crumb forms.
4. Reserve 1 cup of the crumb mixture; press the remaining crumbs firmly into the bottom of the prepared pan to create an even crust.
5. In another bowl, toss the diced peaches with 2 tablespoons sugar, cornstarch, lemon juice, and cinnamon until the fruit is evenly coated.
6. Spread the peach filling over the pressed crust in a smooth, even layer.
7. Sprinkle the reserved crumb mixture evenly over the peaches, ensuring good coverage.
8. Bake for 35–40 minutes, or until the top is golden brown and the filling is bubbling around the edges.
9. Let the bars cool completely in the pan before lifting out using the parchment overhang. Cut into squares and enjoy!

Frequently Asked Questions
Here are quick answers to common questions about Peach Crumb Bars:
- Q: How long does it take to prepare and bake these peach crumb bars?
A: It takes about 20 minutes to prepare the crust and filling—chopping peaches, blending crumbs, and assembling layers—plus 35–40 minutes of baking. Once baked, allow the bars to cool completely (about 30 minutes) before slicing, for a total time of roughly 1½ hours.
- Q: Can I use frozen peaches instead of fresh ones?
A: Yes. Thaw the frozen peaches completely, then drain any excess liquid before tossing them with sugar, cornstarch, lemon juice, and cinnamon to prevent a watery filling.
- Q: How can I prevent the crust from becoming soggy under the peach filling?
A: Make sure to toss the peaches thoroughly with cornstarch, sugar, and lemon juice to thicken released juices. Firmly press the crust layer into the pan, bake until the filling is bubbling, and allow the bars to cool fully so the crust sets before cutting.
- Q: How should I store any leftover bars?
A: Store cooled bars in an airtight container at room temperature for up to 3 days. For longer storage, you can freeze individual squares in a sealed bag for up to one month; thaw at room temperature before serving.
- Q: Can I customize the flavor or texture of these bars?
A: Absolutely. For extra flavor stir ½ teaspoon vanilla extract into the peach filling. For more crunch, fold ¼ cup chopped almonds into the crumb mixture before pressing and sprinkling.
- Q: What’s the best way to achieve a flaky, crumbly topping rather than a greasy one?
A: Keep the butter cold and cut it into small cubes. Use a pastry cutter or your fingertips to blend until coarse crumbs form but avoid overworking the mixture. Reserve one cup for topping and press the rest firmly for the crust.
