Instructions
Preheat oven to 350F. Spray a 9-inch pie dish very well with cooking spray; set aside.
In a large bowl, add the peaches, raspberries, 1/2 cup granulated sugar, cornstarch, and toss gently to combine until all white traces have disappeared; set aside.
In a separate large bowl, add the butter, brown sugar, oats, flour, cinnamon, optional salt, and using two forks or your hands (I find my hands work best and it’s the easiest), cut the butter into the dry ingredients until small pea-sized clumps form and some sandy bits form; set aside.
Give the fruit another stir and turn mixture out into prepared pie dish, scraping out and including any juice that collected in the mixing bowl.
Evenly sprinkle the crumble mixture over the fruit. It looks like a lot when sprinkling, but as the crisp bakes, it seeps down into the fruit and it turns out to be just the right amount.
Place pie dish on a cookie sheet (insurance is case there’s an overflow in the oven) and bake for about 45 to 48 minutes, but start checking at about 35 minutes. Crisp should be bubbling quite vigorously near the edges of dish and bubbling to a lesser degree in center. Topping should be very lightly golden browned and set.
Place pie dish on a wire rack to cool for at least 20 minutes, or overnight, before serving. I prefer crisp to set up for a few hours or overnight, but it can be served warm.
Optionally serve with whipped cream, whipped topping, or ice cream.
