Making your own Triple Berry Crisp is easy! Here’s how to create this incredible dessert:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C).
2. Prepare Berry Filling: In a large bowl, combine strawberries, blueberries, raspberries, granulated sugar, lemon juice, cornstarch, and vanilla extract. Gently mix until the berries are evenly coated.

6. Top Berries: Sprinkle the oat topping evenly over the berry mixture in the baking dish.
7. Bake: Place in the oven and bake for 35-40 minutes, or until the topping is golden brown and the berries are bubbling.
8. Cool: Remove from the oven and let it cool for 10-15 minutes before serving.
