The beauty of this berry crumble lies in its versatility. Use whatever berries you have on hand—blueberries, raspberries, blackberries, or strawberries—and don't worry if they're frozen; they work just as beautifully as fresh. The lemon juice brightens the natural sweetness of the fruit, while the cornstarch ensures the filling sets perfectly without becoming too runny. The oat topping, enriched with brown sugar, cinnamon, and cold butter, bakes into an irresistibly crunchy golden crown that contrasts wonderfully with the warm, tender berries beneath.

  • Fruit Filling: 1 1/2 cups mixed berries (fresh or frozen; e.g., blueberries, raspberries, blackberries, strawberries), 2 tablespoons granulated sugar, 1 teaspoon lemon juice, 1 teaspoon cornstarch
  • Oat Crumble Topping: 1/4 cup rolled oats, 1/4 cup all-purpose flour, 3 tablespoons light brown sugar (packed), 1/4 teaspoon ground cinnamon, pinch of salt, 2 tablespoons unsalted butter (cold and diced)

Instructions

Step 1
Preheat the oven to 350°F (175°C).
Step 2
In a small bowl, gently toss the berries with granulated sugar, lemon juice, and cornstarch until coated.
Step 3
Divide the berry mixture between two small ramekins (about 6 oz each) or use a single small baking dish.
Step 4
In another bowl, combine oats, flour, brown sugar, cinnamon, and salt. Add diced cold butter and use your fingertips to mix until a crumbly texture forms.
Step 5
Sprinkle the oat crumble evenly over the berries.
Step 6
Bake for 25–30 minutes, until the topping is golden brown and the berries are bubbling.
Step 7
Let cool for a few minutes before serving. Enjoy warm, optionally with a scoop of vanilla ice cream.

Zusatztipps für die Zubereitung

For the best texture, make sure your butter is very cold before mixing it into the oat topping—this helps create those perfect buttery crumbles. If using frozen berries, there's no need to thaw them first; simply toss them directly with the sugar, lemon juice, and cornstarch. The cornstarch is essential for thickening the berry juices as they cook, preventing a watery filling. When mixing the crumble topping, work quickly with your fingertips to avoid melting the butter—you want distinct, pea-sized clumps for maximum crunch. If the topping starts to brown too quickly in the oven, tent the ramekins loosely with aluminum foil for the final few minutes of baking.

Varianten und Anpassungen

This recipe is wonderfully adaptable to dietary needs and personal preferences. For a gluten-free version, substitute the all-purpose flour with a gluten-free flour blend and ensure your oats are certified gluten-free. Want extra crunch? Add 2 tablespoons of chopped pecans or almonds to the crumble topping. You can also experiment with different berry combinations—try a mix of tart cherries and sweet blueberries, or go monochromatic with all blackberries for a deeper, richer flavor. For a touch of warmth, add a pinch of nutmeg or cardamom to the topping alongside the cinnamon. If you prefer a sweeter dessert, increase the granulated sugar in the berry filling to 3 tablespoons.

Serviervorschläge

This berry crumble is best served warm, straight from the oven, when the topping is at its crispiest and the berries are still bubbling. Top each ramekin with a generous scoop of vanilla ice cream that melts into the warm fruit, creating an irresistible hot-and-cold contrast. Alternatively, dollop with freshly whipped cream or a spoonful of Greek yogurt for a lighter touch. For an extra elegant presentation, dust with a light sprinkle of powdered sugar and garnish with fresh mint leaves. This dessert pairs beautifully with a cup of hot tea or coffee, making it an ideal finish to a cozy evening meal. Leftovers can be stored covered in the refrigerator for up to 2 days and reheated gently in the oven or microwave.
