Creating the Amazing Blueberry Crisp is straightforward. Just follow these steps to achieve the perfect blend of fruit and crisp topping:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C).

2. Prepare the Blueberries: In a large mixing bowl, combine the fresh blueberries, lemon juice, granulated sugar, and cornstarch. Gently toss the mixture until the blueberries are evenly coated.

3. Transfer to Baking Dish: Pour the blueberry mixture into a greased 9×13-inch baking dish. Spread it out evenly for baking.

4. Make the Crisp Topping: In another bowl, mix together the rolled oats, flour, brown sugar, cinnamon, and salt. Stir the melted butter and vanilla extract into the dry ingredients until well combined and crumbly.

5. Top the Blueberries: Sprinkle the crisp topping evenly over the blueberry mixture in the baking dish. Ensure it covers the blueberries well.

6. Bake: Place the baking dish in the preheated oven. Bake for 30-35 minutes, or until the topping is golden brown and the blueberries are bubbly.

7. Cool: Once baked, remove the dish from the oven and let it cool for about 10-15 minutes. This cooling time allows the filling to set a bit more.

8. Serve: Your Amazing Blueberry Crisp is now ready to serve!
