- 2 tablespoons cornstarch
- 1 tablespoon lemon juice
- 1 teaspoon vanilla extract
For the Crisp Topping:

How to Make Mixed Berry Crisp (Step-by-Step)
This recipe is a straightforward and satisfying way to combine berries and a crisp topping for an unforgettable dessert.
Step 1: Preheat the Oven
Start by preheating your oven to 350°F. There’s something so satisfying about the warm air washing over you as soon as you step into the kitchen.
Step 2: Prepare the Berry Filling
In a large bowl, combine the mixed berries, granulated sugar, cornstarch, lemon juice, and vanilla extract. As I mix, I can already smell the sweet-tart aroma that will soon fill my kitchen. If you’re using frozen berries, make sure to let them thaw slightly for even blending.
Step 3: Transfer to the Baking Dish
Pour this luscious mixture into an 8×8-inch baking dish. I love how vibrant the berries look against the glass—nature’s little jewels all tightly packed together.
Step 4: Make the Crisp Topping
In another bowl, mix the rolled oats, flour, brown sugar, melted butter, cinnamon, and salt until crumbly. The texture should remind you of sandy pebbles, with the melted butter adding a nutty aroma.
Step 5: Assemble and Bake
Sprinkle the oat mixture evenly over the berries. Pop it into the oven and bake for 35-40 minutes, or until the topping is golden brown and the filling is bubbling. Keep an eye on it after the 30-minute mark—nothing beats the sight of bubbling juices peeking through a golden crust!
Step 6: Cool and Serve
Allow it to cool for at least 10 minutes before diving in. The crisp will firm up a bit during this time. Serve warm with a scoop of vanilla ice cream, if you desire—a classic pairing that elevates the experience.

Common Mistakes to Avoid
- Using Only One Type of Berry: Stick with a mix! The interplay of flavors makes a more complex and satisfying dessert.
- Overmixing the Topping: You want it crumbly, not a uniform batter. This helps create that delightful texture!
- Skipping the Cooling Step: Allowing the crisp to cool slightly helps the juices set, making it easier to serve.
Tips and Tricks for Success
- Use Fresh, Seasonal Berries: If you can find local, seasonal berries, grab them! They’ll give you the most vibrant flavors and colors.
- Frozen Berries Work Too: Don’t worry if you can’t find fresh berries in winter; frozen berries can be just as delicious and convenient. Just remember not to thaw them fully before mixing.
- Personalize Your Topping: Feel free to add nuts or coconut flakes to the topping for an additional layer of flavor.
Variations
- Swap out mixed berries for a single type like blackberries or peaches.
- Add a splash of orange juice or zest for a citrusy twist.
- Use gluten-free flour in the topping for a gluten-free version.
How to Serve
- Serve warm with a generous scoop of vanilla ice cream.
- Pair with whipped cream for a lighter option.
- Enjoy it cold straight from the refrigerator as a delightful breakfast treat.

Make Ahead and Storage
- Make Ahead: Prepare the berry filling and crisp topping separately and store them in the refrigerator for up to 24 hours before baking.
- Storage: Store any leftovers in an airtight container in the refrigerator for up to 3 days.
- Reheating: Reheat in the oven at 350°F until warmed through or enjoy cold straight from the fridge.
- Freezing: The crisp can be frozen before baking; just assemble it and cover tightly. Bake from frozen, adding a few extra minutes to the cooking time.
