Creating Mixed Berry Crisp is straightforward. Just follow these simple steps:

1. Preheat: Begin by preheating your oven to 350°F (175°C).
2. Prepare Berries: In a large mixing bowl, combine the mixed berries, granulated sugar, lemon juice, vanilla extract, and cornstarch. Stir gently to coat the berries evenly.
3. Transfer to Baking Dish: Pour the berry mixture into a greased 8×8 inch baking dish, spreading it evenly.
4. Make Crisp Topping: In another bowl, combine rolled oats, all-purpose flour, brown sugar, cinnamon, and salt. Mix well.
5. Incorporate Butter: Pour the melted butter into the dry mixture, and stir until crumbly.
6. Spread Topping: Evenly sprinkle the crisp topping 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 top is golden brown and the berry filling is bubbly.
8. Cool: Remove from the oven and let it cool for about 10 minutes before serving.
9. Serve Warm: It’s best served warm, either on its own or with a scoop of ice cream for extra indulgence.

These steps will ensure your mixed berry crisp turns out wonderfully, producing a beautiful dessert to impress everyone!
