1/2cupunsalted butter (grated or cut into small pieces)
Instructions
Preheat oven to 375F. Grease a 9x13" baking dish and set aside.
In a large mixing bowl, prepare filling by combining pears, sugar, cinnamon, lemon juice, and cornstarch. Toss to coat the pears well. Pour the mixture into the prepared baking dish.
In a separate medium mixing bowl, begin preparing the topping by combining flour, oats, brown sugar, sugar, cinnamon, and pecans. Stir to combine.
Add the butter to the topping ingredients, using two forks or a pastry blender (or your fingers) to mix everything together until the butter pieces are no larger than pea-sized.
Sprinkle the topping evenly over the pears in the baking dish.
Bake in preheated oven for about 35 minutes, or until the topping is golden-brown and filling is bubbly.
Let cool slightly to allow the filling to thicken a bit, then serve warm. Top each serving with vanilla ice cream or whipped cream, if desired.
Notes
I don't bother peeling the pears, because the peeling gets so soft when baked. But if you prefer, you can peel the pears before slicing.
You can use walnuts instead of pecans, or omit the nuts entirely if you need a nut-free dessert.
Leftover cobbler can be covered well with plastic wrap and stored at room temperature for 2-3 days or refrigerated for 3-5 days.
