Creating a mouthwatering Mixed Berry Crisp is as easy as following these simple steps:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C). Grease an 8×8-inch baking dish to prevent sticking.
2. Prepare the Berries: In a large bowl, combine the mixed berries, 1/4 cup of the granulated sugar, cornstarch, lemon juice, and vanilla extract. Gently toss to coat the berries evenly.
3. Transfer to Baking Dish: Pour the berry mixture into the prepared baking dish, spreading it out evenly.
4. Create the Topping: In another bowl, mix the rolled oats, remaining 1/2 cup of granulated sugar, flour, cinnamon, and salt. Stir until thoroughly combined.
5. Add Butter: Pour the melted butter into the oat mixture and stir until the dry ingredients are just moistened.
6. Spread Topping: Sprinkle the topping evenly over the berry mixture in the baking dish.
7. Bake: Place the dish in the preheated oven and bake for 30-35 minutes, or until the berries are bubbling and the topping is golden brown.
8. Cool: Remove from the oven and allow to cool for about 10 minutes. This will help the filling set slightly before serving.

With these steps, you’ll achieve a perfectly baked Mixed Berry Crisp ready to be enjoyed!
