Why This Crumble Recipe Works

From the first spoonful of juicy berry filling to the crunchy oat topping, this dessert combines textures and flavors that celebrate summer fruits in every bite. Bright berries meet a cinnamon-kissed, buttery streusel for a classic fruit crumble experience.

Ingredients for the Ultimate Berry Crumble

• 3 cups mixed berries (1 cup blackberries, 1 cup raspberries, 1 cup blueberries)
• 1/2 cup granulated sugar
• 2 tbsp cornstarch
• 1 tsp lemon zest
• 1 tbsp fresh lemon juice
• 2 cups all-purpose flour
• 1 cup old-fashioned rolled oats
• 1 cup packed brown sugar
• 1/2 tsp ground cinnamon
• 1/4 tsp salt
• 1 cup (2 sticks) cold unsalted butter, cut into small cubes

Instructions to Build Your Berry Crumble

1. Preheat & Prep: Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
2. Mix the Filling: In a large bowl, gently toss mixed berries with sugar, cornstarch, lemon zest, lemon juice, and a pinch of salt. Transfer to the prepared dish.
3. Make the Crumble Topping: In a separate bowl, whisk together flour, rolled oats, brown sugar, cinnamon, and salt. Cut in cold butter with a pastry cutter or fork until mixture resembles coarse crumbs.
4. Assemble: Evenly sprinkle the crumb topping over the berry layer, covering all fruit pockets.
5. Bake: Bake for 45–55 minutes, or until the top is golden brown and the fruit is bubbling around the edges.
6. Cool & Serve: Let your crumble rest 10 minutes to thicken. Serve warm, optionally with vanilla ice cream or whipped cream.

Tips for the Perfect Crumble

• Chill Your Butter: Cold butter ensures a flaky, sandy topping.
• Adjust Sweetness: Taste your berries—add more sugar if tart, less if ultra-sweet.
• Variation: Swap half the berries for stone fruit like peaches or plums.
• Storage: Cover leftovers and refrigerate up to 3 days; reheat at 350°F for a crisp top.
