Key Ingredients
Before we get baking, let’s gather everything you need to create that perfect balance of tender fruit and crunchy topping.
- 4 cups peaches, sliced: Ripe peaches bring juicy sweetness and tender texture to the base.
- 2 cups blueberries: Plump berries add a burst of tangy color and flavor contrast.
- 1/4 cup granulated sugar: Sweetens the fruit filling to balance peach tartness.
- 2 tbsp lemon juice: Brightens and enhances the natural fruit flavors.
- 2 tbsp cornstarch: Thickens fruit juices for a perfectly set filling.
- 1 cup all-purpose flour: Forms the foundation of the buttery crumble topping.
- 1 cup old-fashioned oats: Provides hearty texture and crispness to the crumble.
- 1/2 cup brown sugar: Adds rich, caramel-like sweetness to the topping.
- 1/4 cup granulated sugar: Helps the topping caramelize under the oven’s heat.
- 1 tsp ground cinnamon: Infuses cozy warmth and depth to both fruit and topping.
- 1/4 tsp salt: Balances sweetness and enhances overall flavors.
- 1/2 cup unsalted butter, cold and cubed: Creates flaky, golden crumbs when cut into the dry mix.
How To Make Blueberry Peach Crumble
This crumble comes together quickly, layering a luscious fruit filling with a crisp oat topping that bakes to golden perfection. You’ll first prep your fruits, then whisk together the crumble ingredients before combining everything in a baking dish. Follow these detailed steps to ensure each scoop has that perfect contrast of juicy berries and crunchy topping:
1. Preheat the oven to 350°F (175°C) so it’s evenly heated before baking.
2. In a large bowl, combine the sliced peaches, blueberries, granulated sugar, lemon juice, and cornstarch. Gently toss until each piece of fruit is evenly coated, avoiding bursting the berries.
3. Transfer the fruit mixture to a greased 9×9-inch baking dish, spreading it out in an even layer.
4. In another bowl, whisk together the flour, oats, brown sugar, granulated sugar, cinnamon, and salt until fully combined.
5. Add the cold, cubed butter and use a pastry cutter (or clean fingers) to work it into the dry ingredients until the mixture resembles coarse crumbs.
6. Sprinkle the crumble topping evenly over the fruit layer, covering all edges to catch bubbling juices.
7. Bake for 35–40 minutes, or until the topping turns golden brown and the fruit filling is bubbling around the sides.
8. Allow to cool for about 10 minutes before serving so the filling can thicken and set slightly.
Serving Suggestions
This Blueberry Peach Crumble is a versatile dessert that shines whether it’s a casual family treat or the grand finale of a special dinner.

Tips For Perfect Blueberry Peach Crumble
Nailing the perfect crumble is all about timing and temperature. Make sure your fruits are ripe but firm, and keep your butter cold so the topping bakes up light and flaky. Here are some friendly pointers to elevate every batch:
- Allow to cool slightly before serving to let the filling thicken.
- Serve warm with vanilla ice cream or whipped cream.
- Store leftovers tightly covered in the refrigerator for up to 3 days.
- Reheat individual portions in the oven or microwave until warmed through.
How To Store It
To keep your crumble tasting fresh and maintain that crumbly topping texture, proper storage is key. Follow these simple methods to enjoy leftovers at their best:
- Airtight container: Transfer cooled crumble to a sealed container before refrigerating to lock in moisture.
- Cover baking dish: If leaving in the dish, seal with plastic wrap or aluminum foil to prevent drying out.
- Chill promptly: Place in the fridge within two hours of baking to maintain freshness, up to three days.
- Separate portions: Wrap individual servings in plastic film for quick grab-and-go treats.
Frequently Asked Questions
Here are some quick answers to questions you might have while baking or storing this crumble:
- Can I use frozen blueberries or peaches instead of fresh fruit?
Yes, you can substitute frozen fruit for fresh. Thaw the frozen berries and peaches first, then drain off any excess liquid before tossing with the sugar and cornstarch. This prevents the filling from becoming too watery. You may need to extend the baking time by about 5–10 minutes if the fruit is still slightly cold.
- What is the role of cornstarch in this recipe?
Cornstarch acts as a thickening agent. When heated, it absorbs the fruit’s juices and forms a gel-like consistency, ensuring the filling isn’t runny. Without it, the fruit juices may remain too liquid, resulting in a soggy topping and underwhelming texture.
- How can I tell when the crumble is fully baked?
The topping should be a deep golden brown and have a firm, crumbly texture. You should also see the fruit juices bubbling up around the edges of the baking dish. If the topping is pale or the juices are not bubbling, continue baking in 5-minute intervals until both cues are met.
- Can I make the crumble topping gluten-free?
Absolutely. Replace the all-purpose flour with a 1:1 gluten-free baking flour blend and use certified gluten-free old-fashioned oats. The rest of the ingredients remain the same, and you’ll still achieve a crisp, flavorful topping.
- What’s the best way to store and reheat leftovers?
After cooling completely, cover the crumble tightly with plastic wrap or transfer to an airtight container and refrigerate for up to 3 days. To reheat, place individual portions on a baking sheet and warm in a 325°F (160°C) oven for about 10–12 minutes, or microwave single servings for 60–90 seconds until heated through.
- Why should I use cold butter for the topping?
Cold butter cut into small cubes creates distinct flaky crumbs when mixed into the dry ingredients. If the butter softens too much, the topping can become greasy and dense rather than light and crumbly. Work quickly or chill the butter and tools if your kitchen is warm.
- Can I prepare this crumble ahead of time?
Yes. Assemble both the fruit filling and crumble topping and keep them separately covered in the refrigerator for up to 24 hours. When ready to bake, layer the topping over the fruit in the dish and bake at 350°F (175°C). You may need an extra 5 minutes of baking time if the ingredients are cold from the fridge.
