These Fresh Peach Crumb Bars are an easy summer dessert made with ripe peaches, a buttery shortbread-style crust, and a golden crumb topping. Bake them in a 9 x 13-inch pan at 375°F (190°C) for 45–50 minutes, then cool for at least one hour before slicing into about 24 wonderfully tender bars.
Every bite brings together juicy peach filling, bright lemon, gentle cinnamon, and a crisp, buttery crumble. They are simple enough for a casual family treat yet pretty enough for a picnic, brunch, bake sale, or summer dinner party.

Fresh Peach Crumb Bars are the kind of dessert that disappears quickly because they offer several textures in one easy square. The bottom is buttery and sturdy, the middle is soft and fruity, and the top bakes into a rustic crumble with lightly crisp edges.
The recipe uses fresh peaches rather than canned fruit, so the filling tastes bright and naturally fragrant. A little lemon juice keeps the sweetness balanced, while cornstarch helps the peach juices turn into a spoonable, sliceable filling as the bars cool.
This is also a forgiving dessert for busy bakers. There is no separate pastry to roll, and the same crumb mixture creates both the crust and the topping. For another fruit-forward dessert idea, you may also enjoy our peach pie with a tender patty cake crust.
Ingredients You’ll Need
The crumb mixture begins with all-purpose flour, granulated sugar, baking powder, salt, cold unsalted butter, and one large egg. These ingredients create a dough that can be pressed into the pan while still breaking into distinct crumbs for the top.
- Fresh peaches: Use approximately 5–6 medium peaches to produce 4 cups of peeled, pitted, sliced or chopped fruit.
- Cornstarch: Four teaspoons thicken the peach juices without making the filling heavy.
- Lemon juice: One teaspoon adds a clean, fresh note that keeps the fruit from tasting overly sweet.
- Cinnamon: A pinch is optional, but it adds cozy bakery flavor to either the crumb mixture, the peach filling, or both.
Select peaches that are ripe enough to smell fragrant and yield slightly when pressed, but are still firm enough to hold their shape. Very soft peaches release more liquid and may leave the bottom crust softer than desired.
How to Make It Step-by-Step
Step 1: Heat the oven to 375°F (190°C), then prepare a 9 x 13-inch baking pan. Greasing works well, but parchment paper with a little overhang makes it much easier to lift the finished slab out for neat cutting.
Step 2: In a large bowl, whisk together 3 cups of flour, 1 cup of granulated sugar, 1 teaspoon of baking powder, 1/4 teaspoon of salt, and a pinch of cinnamon if using. Mixing the dry ingredients first distributes the baking powder and seasoning evenly throughout the crumb mixture.
Step 3: Add the cold butter in small pieces and cut it in with a pastry cutter, or rub it into the flour mixture with your fingertips. Stop when the mixture looks like coarse crumbs, then add the egg and mix until a crumbly dough forms; do not knead it into a smooth ball.
Step 4: Transfer approximately half of the crumb mixture to the prepared pan. Press it firmly and evenly across the bottom, paying special attention to the corners so the peach juices have a solid base to rest on.
Step 5: In a separate bowl, gently combine the peeled, pitted peaches with 1/2 cup granulated sugar, 4 teaspoons cornstarch, 1 teaspoon lemon juice, and a pinch of cinnamon if it was not used in the crumbs. Let the mixture stand briefly so the fruit releases some juice and the cornstarch coats every piece.
Step 6: Spread the peach mixture over the crust in an even layer. If a large amount of liquid collects in the bowl, use a slotted spoon to transfer the fruit while leaving behind only a little of the excess juice.
Step 7: Crumble the remaining dough evenly over the peaches. Some small gaps are welcome because they allow the filling to peek through, but distribute the crumbs from edge to edge for a balanced topping.
Step 8: Bake for 45–50 minutes, until the top is lightly golden and the peach filling bubbles around the edges. Set the pan on a rack and cool completely for at least one hour; for especially clean slices, chill the cooled bars briefly before cutting.
Pro Tips for Perfect Peach Bars
Cold butter is one of the most important details in this recipe. It keeps the crumb mixture textured instead of greasy, giving the crust and topping a tender bite with crisp little edges.
Press the bottom crust with enough firmness that it holds together, but avoid compacting the topping. A firm base supports the fruit, while loosely scattered crumbs remain pleasantly rough and golden after baking.
- For juicy peaches: Add about 1 additional teaspoon of cornstarch if the fruit is unusually ripe or watery.
- For even pieces: Slice the peaches into similarly sized pieces so they soften at the same rate.
- For neat edges: Cool completely before cutting, and use a sharp knife wiped clean between slices.
- For easy removal: Line the pan with parchment paper, leaving handles on two opposite sides.
Watch the edges near the end of baking. Bubbles around the peach filling are a useful sign that the cornstarch has activated, while a lightly golden top shows the crumb mixture is baked without becoming too dark.
Serving Suggestions
Serve these bars at room temperature for a soft, buttery texture, or chill them for a firmer, cleaner bite. A spoonful of whipped cream or a scoop of vanilla ice cream makes the warm peach flavor especially inviting.
For a dessert table, arrange the bars on a platter with thin peach slices and a small dusting of powdered sugar added just before serving. Their golden color pairs beautifully with a cool glass of raspberry basil lemonade at a summer gathering.
They also fit nicely into a casual brunch spread beside coffee, tea, or other baked treats. If you prefer a citrus-centered dessert, our bright lemon brownies make a lovely second option.
Storage and Make-Ahead Advice
Store fully cooled bars in an airtight container. They can be kept at room temperature for a short serving window, or refrigerated when you want the filling to remain firm and the bars to last longer.
Place parchment between layers if stacking the bars. Chilled pieces can be enjoyed cold, or brought to room temperature before serving; a brief warm-up may soften the crust, so heat gently and avoid overheating the peach filling.
For a larger meal, prepare the bars earlier in the day so they have plenty of time to set. Their sweet finish works well after savory sides such as garlic chive butter roasted potatoes or a comforting dish of loaded baked beans.
Fresh Peach Crumb Bars
Ingredients
Method
- Heat the oven to 375°F (190°C). Grease a 9 x 13-inch baking pan or line it with parchment paper, leaving some overhang for lifting the baked bars out later.
- Whisk together the flour, 1 cup granulated sugar, baking powder, salt, and optional cinnamon. Cut in the cold butter until coarse crumbs form, then mix in the egg until a crumbly dough comes together.
- Press about half of the crumb mixture firmly into the prepared pan to make an even bottom crust. Combine the peaches, 1/2 cup sugar, cornstarch, lemon juice, and optional cinnamon in a separate bowl.
- Let the peach mixture stand briefly, then spread it evenly over the crust. Sprinkle the remaining crumb dough over the fruit.
- Bake for 45–50 minutes, until the topping is lightly golden and the peach filling bubbles around the edges. Cool completely in the pan for at least one hour before cutting.
Notes
Final Thoughts
These Fresh Peach Crumb Bars turn a handful of ripe summer peaches into a dependable, crowd-pleasing dessert. The buttery crumb crust, jammy fruit center, and golden topping make every square taste homemade in the best possible way.
Remember the three details that matter most: choose ripe but firm peaches, use cold butter, and let the bars cool completely before slicing. Make a pan for your next picnic or family dinner, and expect the last piece to vanish before you get a second serving.
