Ingredients

- Granulated Sugar: Adds sweetness and helps balance the tartness of the berries.
- Cornstarch: Thickens the berry filling, ensuring a smooth, cohesive texture without being too runny.
- Cinnamon: Adds warmth and enhances the flavors of the berries.
- All-Purpose Flour: Forms the base of the crumble topping and provides structure.
- Rolled Oats: Give the topping a chewy texture and a nutty flavor.
- Brown Sugar: Adds sweetness and a hint of molasses flavor that pairs beautifully with the oats.
- Salt: Balances the sweetness and enhances all the flavors.
- Unsalted Butter: Creates the crumbly texture of the topping, adding richness and flavor.
Alternative Ingredient Suggestions
If you’re looking for ingredient substitutions or have dietary preferences, here are a few ideas:
- For a gluten-free option: Use gluten-free flour and oats. Make sure the oats are certified gluten-free.
- For vegan-friendly options: Replace the butter with vegan butter or coconut oil.
- For a sugar alternative: You can substitute coconut sugar, maple syrup, or honey for granulated sugar.
Step-by-Step Instructions
- Prepare the Filling: Preheat your oven to 375°F (190°C) and grease an 8×8-inch or 9×9-inch baking dish. In the dish, combine the mixed berries, granulated sugar, cornstarch, and cinnamon. Stir until the berries are evenly coated, and set them aside.
- Make the Streusel Topping: In a small bowl, mix together the flour, oats, brown sugar, and salt. Add the cold diced butter and, using your hands or a fork, cut the butter into the dry ingredients until the mixture resembles coarse crumbs.
- Assemble the Crisp: Evenly sprinkle the streusel topping over the berry mixture in the baking dish.
- Bake: Place the dish in the preheated oven and bake for 35-40 minutes, or until the topping is golden brown and the berry filling is bubbling.
- Serve: Let the crisp cool for a few minutes before serving. Top with a scoop of vanilla ice cream for an extra indulgence!

Tips & Tricks
- Make Ahead: You can prepare the filling and topping ahead of time. Store them separately in the fridge and assemble the crisp just before baking. This is a great time-saver for busy nights or dinner parties.
- Frozen Berries: If you don’t have fresh berries, you can use frozen mixed berries. There’s no need to thaw them; simply increase the baking time by about 5 minutes.
- Cornstarch is Essential: Don’t skip the cornstarch—it helps prevent the berry filling from becoming too runny. If you don’t have cornstarch, you can substitute it with all-purpose flour.
Pairing Ideas and Variations
While this Mixed Berry Crisp is perfect on its own, here are some ideas for making it even more special:
- Serve with Ice Cream: Vanilla ice cream is the perfect companion for the warm, juicy crisp. The creaminess complements the crunch of the topping and the sweetness of the berries.
- Add Nuts: For added texture and flavor, sprinkle chopped walnuts or almonds on top of the streusel before baking.
- Try Other Fruits: While mixed berries are fantastic, you can experiment with other fruits such as peaches, apples, or rhubarb. Just make sure to adjust the sugar and cornstarch levels based on the sweetness and juiciness of the fruit.
