Let’s get cooking! Follow these simple steps to bring this delightful dessert to life:

1. Preheat your oven to 375°F (190°C). Grease a 9-inch baking dish with butter or cooking spray.
2. In a large mixing bowl, combine the strawberries, rhubarb, granulated sugar, cornstarch, and vanilla extract. Toss until the fruit is evenly coated. This step reminds me of helping my abuela mix her traditional fruit fillings, always ensuring each piece was perfectly coated.
3. Pour the fruit mixture into the prepared baking dish, spreading it out evenly.
4. In a separate bowl, mix together the rolled oats, all-purpose flour, brown sugar, ground cinnamon, and salt. Stir in the melted butter until the mixture resembles coarse crumbs. This topping is inspired by the crunchy textures I loved in my grandmother’s desserts.
5. Sprinkle the oat mixture evenly over the fruit, covering it completely.
6. Bake for 40-45 minutes, or until the topping is golden brown and the fruit is bubbling. The aroma that fills your kitchen will surely remind you of warm, cozy afternoons spent baking with loved ones.
7. Let the crisp cool for a few minutes before serving. For an extra touch of indulgence, add a scoop of vanilla ice cream on top.
