Preheat oven to 350 degrees.
Spray a baking dish (about 9x9) with cooking spray.
Fold together the raspberries, sugar and cornstarch until evenly combined and spread into bottom of prepared baking dish.
In a separate bowl, combine the oats, pecans, brown sugar, butter and pinch of salt. Using a pastry cutter, cut and mix together the topping ingredients until very well combined and resembling the texture of wet sand.
Evenly spread the topping over the raspberries in the dish.
Bake on center rack of oven for 30-40 minutes until the topping is beginning to brown.
Allow to cool for about 30 minutes before serving topped with plenty of vanilla ice cream.
