How to Make It
Preheat oven to 350°.
To prepare streusel, weigh or lightly spoon flour into a dry measuring cup; level with a knife. Combine flour, regular oats, brown sugar, 1/2 teaspoon cinnamon, 1/4 teaspoon allspice, and salt in a medium bowl. Add butter, stirring with a fork until crumbly. Set aside.
To prepare filling, combine wine and granulated sugar in a large nonstick skillet over medium-high heat; bring to a simmer, stirring until sugar dissolves. Reduce heat to medium. Add lemon rind, 1/2 teaspoon cinnamon, 1/2 teaspoon allspice, and sliced pears to pan, stirring to coat; simmer for 15 minutes or until the pears are tender.
Spoon pear mixture into an 8-inch square baking dish coated with cooking spray. Sprinkle streusel evenly over pear mixture. Bake at 350° for 30 minutes or until bubbly and lightly browned. Serve with whipped topping. Sprinkle with 1/8 teaspoon cinnamon, if desired.
