Warm Fruit Crisp Recipe:

1. Preheat the Oven:
   • Preheat your oven to 350°F (175°C). Grease a 9-inch baking dish or an equivalent-sized dish.
2. Prepare the Fruit Filling:
   • In a large bowl, combine the mixed fruit, sugar, lemon juice, vanilla extract, cornstarch, and cinnamon (if using). Stir until the fruit is evenly coated and the cornstarch is dissolved.
   • Transfer the fruit mixture into the prepared baking dish, spreading it evenly.
3. Make the Crumble Topping:
   • In a separate bowl, combine the oats, flour, brown sugar, cinnamon, and salt. Add the cold, cubed butter.
   • Use a pastry cutter, fork, or your fingers to work the butter into the dry ingredients until the mixture resembles coarse crumbs. Stir in the chopped nuts, if using.
4. Assemble the Crisp:
   • Evenly sprinkle the crumble topping over the fruit filling, covering it completely.
5. Bake:
   • Place the baking dish in the oven and bake for 40-45 minutes, or until the topping is golden brown and the fruit is bubbling around the edges.
6. Serve:
   • Remove from the oven and let it cool for a few minutes. Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream for the ultimate treat.

Optional Variations:

• Apple Crisp: Use a mix of tart apples (like Granny Smith) and sweet apples (like Fuji or Honeycrisp) for a more traditional flavor.
• Peach and Berry Crisp: Combine fresh or frozen peaches with mixed berries for a sweet-tart combination.
• Coconut Crisp: Add 1/4 cup of shredded coconut to the crumble topping for extra flavor and texture.

This Warm Fruit Crisp is the perfect balance of sweet, tangy, and crunchy. The combination of tender fruit and golden crumble is irresistible, especially when paired with ice cream or whipped cream.
