Peach Crumb Bars
These Peach Crumb Bars are the ultimate summer dessert, bursting with juicy peach filling and topped with a buttery golden crumble. Fresh, frozen, canned, or jarred peaches all work beautifully, making this a year-round crowd-pleaser.
The Only Peach Dessert You'll Need This Summer
If there's one thing summer absolutely demands, it's a peach dessert that lets the fruit shine without making you slave over a hot stove for hours. These Peach Crumb Bars are exactly that. Picture a buttery, golden oat crust layered with sweet, lightly spiced peach filling and finished with a generous crumbly topping that bakes up crisp at the edges and tender in the middle. They're somewhere between a peach pie and a fruit crisp, and honestly, they might be better than both.
Whether you're making a cookout dessert for a crowd, looking for easy dessert recipes with fruit, or just trying to figure out the best things to bake this summer, this is your answer. And here's the best part: you don't need picture-perfect fresh peaches. This recipe works beautifully with fresh, frozen, canned, or jarred peaches, so you can make it any time of year.
Getting great results with bar desserts comes down to a few key things: a quality baking pan that distributes heat evenly, cold butter worked in properly, and good vanilla extract. Using the right tools means the difference between a soggy bottom crust and one that holds its shape perfectly when you slice into it.
Why These Bars Work for Every Occasion
One of the reasons this recipe has become a go-to is its extraordinary flexibility. Heading to a cookout? These bars travel far better than a pie. Hosting a summer brunch? Slice them small and serve with a dollop of whipped cream. Need a make-ahead peach dessert for a dinner party? Bake them the day before and they'll taste even better once the filling sets.
They also solve the classic summer dilemma of having a glut of peaches and no idea what to do with them. Got a basket of ripe fresh peaches? Perfect. Have a jar of peaches sitting in your pantry? That works too. In the middle of February and craving something peachy? Grab a can.
Chef's Tip: If you're using fresh peaches, there's no need to blanch them for this recipe. Just peel, pit, and dice. A vegetable peeler works surprisingly well on ripe peaches and is faster than blanching.
The Secret to the Best Crumb Topping
The crumb layer in these bars does double duty: it forms the base and the topping, which means less cleanup and a beautifully cohesive bar. The key to getting that perfect, slightly sandy crumble texture is keeping your butter cold.
Work quickly with your fingertips, or use a pastry cutter, to break the cold butter into the flour and oat mixture until you have mostly pea-sized pieces with some larger shaggy bits. Those uneven clumps are what give you those irresistible golden crunch clusters on top after baking.
Here's how to get the layers right:
- Press the base firmly. Pack it down with the bottom of a measuring cup for an even, sturdy crust that won't crumble when you cut it.
- Don't overthink the topping. Scatter it loosely; gaps are fine. The filling bubbling up through them is actually beautiful.
- Let it cool completely. This is the hardest part. Cutting into warm bars means a mess. Give them a full 1 to 2 hours, or pop the pan in the fridge for 30 minutes before slicing.
Fresh Peaches vs. Canned vs. Jarred: What's the Difference?
If you've been searching for recipes with jarred peaches or wondering whether canned peach pie filling desserts can rival fresh-fruit versions, the honest answer is: yes, with a small adjustment.
Fresh peaches give you the brightest flavor and the most control over sweetness, especially at peak summer ripeness. Frozen peaches are an excellent year-round substitute since they're typically frozen at peak ripeness. Just thaw and drain them well before using.
Canned or jarred peaches work beautifully here because the cornstarch in the filling compensates for any extra liquid. Drain them thoroughly and cut back the added sugar by a tablespoon or two, since packed fruit tends to be sweeter. If you're using canned peach pie filling, you can skip the sugar and cornstarch in the filling entirely and just fold in a pinch of cinnamon and lemon juice to brighten it up.
Chef's Tip: For peach desserts that taste like summer even in January, stock up on frozen sliced peaches during peak season. They're often just as flavorful as fresh and available year-round.

Peach Crumb Bars
These Peach Crumb Bars are the ultimate summer dessert, bursting with juicy peach filling and topped with a buttery golden crumble. Fresh, frozen, canned, or jarred peaches all work beautifully, making this a year-round crowd-pleaser.
Ingredients
- 2 cups all-purpose flour, spooned and leveled
- 3/4 cup old-fashioned rolled oats
- 1/2 cup granulated sugar, divided
- 1/2 cup packed light brown sugar, packed
- 1/2 tsp baking powder
- 1/4 tsp salt
- 1/2 tsp ground cinnamon, divided
- 3/4 cup unsalted butter, cold, cut into small cubes
- 1 large egg, lightly beaten
- 1 tsp vanilla extract
- 3 cups fresh, frozen, or jarred peaches, peeled and diced into 0.5-inch pieces; if using canned or jarred, drain well
- 2 tbsp cornstarch
- 1 tbsp lemon juice, freshly squeezed
Instruction
Preheat your oven to 350 degrees F (175 degrees C). Grease a 9x13-inch baking pan and line it with parchment paper, leaving a slight overhang on the sides for easy lifting.
In a large bowl, whisk together the flour, oats, brown sugar, 0.25 cup of granulated sugar, baking powder, salt, and 0.25 tsp of cinnamon until evenly combined.
Add the cold cubed butter, egg, and vanilla extract. Use your fingertips or a pastry cutter to work the butter into the dry ingredients until the mixture resembles coarse, clumpy crumbs. Do not overmix; you want pea-sized butter pieces for a crumbly texture.
Press roughly two-thirds of the crumb mixture firmly and evenly into the bottom of the prepared pan to form the crust layer. Set the remaining crumb mixture aside.
In a separate medium bowl, toss the diced peaches with the remaining 0.25 cup of granulated sugar, cornstarch, lemon juice, and remaining 0.25 tsp of cinnamon. Stir until the peaches are evenly coated.
Spread the peach filling evenly over the crust layer in the pan.
Scatter the reserved crumb topping evenly over the peach filling, breaking any large clumps apart with your fingers.
Bake for 38 to 42 minutes, until the topping is golden brown and the peach filling is bubbling around the edges.
Remove from the oven and let the bars cool completely in the pan on a wire rack, at least 1 to 2 hours, before lifting them out and slicing. Cutting them warm will cause the bars to fall apart.

Notes
Serving, Storing, and Making Ahead
These bars are genuinely one of the most flexible desserts you can add to your rotation. Here are a few ways to serve and store them:
- Serve warm with a scoop of vanilla ice cream for the full experience.
- Serve at room temperature for cookouts and potlucks where they're easy to pass around.
- Refrigerate overnight for cleaner slices and a slightly denser, fudgier texture in the filling.
For storing, cover the pan tightly with foil or transfer bars to an airtight container. They keep at room temperature for 2 days, in the fridge for up to 5 days, and in the freezer for up to 2 months. Individual bars wrapped in plastic wrap freeze perfectly and make an incredible lunchbox treat or late-night snack straight from the freezer.
If you're making them for a party, bake the day before and slice just before serving for the neatest presentation. A sharp knife run under hot water and wiped dry between cuts makes a world of difference.
Summer baking doesn't get better than this. Sweet, buttery, peachy, and endlessly adaptable, these Peach Crumb Bars are the kind of recipe you'll come back to all season long.
