Cook Berry Crumble Like This

Follow these simple steps to create your scrumptious Berry Crumble:
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your crumble bakes evenly and achieves that perfect golden-brown color.
Step 2: Prepare the Berry Filling
In a large mixing bowl, combine the frozen mixed berries, freshly squeezed lemon juice, granulated sugar, and cornstarch. Mix gently until the berries are well coated. The cornstarch will help thicken the juices as they cook, creating a delicious sauce.
Step 3: Assemble the Berry Filling
Grease your baking dish with the teaspoon of unsalted butter. Pour the berry mixture into the prepared dish, spreading it evenly across the bottom.
Step 4: Make the Crumble Topping
In another bowl, whisk together the all-purpose flour, dark brown sugar, ground cinnamon, and salt. Cut in the cold cubed butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. This will create that delightful crumbly texture!
Step 5: Top the Berries
Evenly sprinkle the crumble topping over the mixed berries in the baking dish. Don’t worry if it’s not perfectly even; the rustic look adds to the charm!
Step 6: Bake
Place the baking dish in the preheated oven and bake for about 35-40 minutes, or until the top is golden brown and the berry filling is bubbling around the edges.
Step 7: Serve and Enjoy!
Once your Berry Crumble is out of the oven, let it cool for a few minutes. Serve warm with a scoop of vanilla ice cream on top for the ultimate dessert experience!
Substitutions by Category

If you’re missing an ingredient or two, here are some substitutions you can make:
- Mixed Berries: You can use fresh berries if they’re in season or substitute with any single type of frozen berry like blueberries or raspberries.
- Sugar: Coconut sugar or honey can be used in place of granulated sugar, but adjust quantities to taste.
- Flour: For a gluten-free option, use a 1:1 gluten-free flour blend.
- Butter: Coconut oil or a dairy-free butter alternative works well for a vegan version.
Errors to Dodge
To ensure your Berry Crumble turns out perfectly, keep these tips in mind:
- Don’t skip the cornstarch; it’s vital for thickening the berry juices.
- Avoid overmixing the crumble topping to keep it light and crumbly.
- Watch the baking time closely; every oven is different, and you want to avoid burning the topping.
- Let it cool slightly before serving to allow the filling to set a bit; this makes for easier serving.
Make Ahead Like a Pro
Want to prepare your Berry Crumble in advance? Here’s how:
- Assemble the berry filling and crumble topping separately, then store them in the refrigerator for up to 24 hours before baking.
- You can also freeze the assembled crumble (before baking) for up to 3 months. Just thaw it in the refrigerator overnight before baking.
- If you have leftovers, store them in an airtight container in the fridge for up to 3 days; reheat in the oven or microwave.
Troubleshooting Q&A
What if my crumble topping is too wet?
If your crumble topping is too wet, it may be due to too much butter or moisture in the mixture. Add a little more flour until you achieve a crumbly texture.
Can I use fresh berries instead of frozen?
Absolutely! Fresh berries can be used, but you may need to adjust the sugar depending on their sweetness, and they will require less baking time.
Why is my crumble too soggy?
A soggy crumble usually results from not using enough cornstarch or baking it for too short a time. Make sure to follow the recipe closely and bake until bubbly!
How do I store leftover Berry Crumble?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven for the best texture.
