Instructions

Step 1: Preheat oven to 350°F. In a bowl, mix 1 1/2 cups oats, 1/2 cup unsalted butter, and 1/2 cup granulated sugar until crumbly. Press into a 9x13-inch baking dish, creating a crust.
Step 2: In a large bowl, toss 3 cups diced apples with 2 tsp cinnamon, 1/2 tsp nutmeg, 2 tbsp cornstarch, and 1/4 cup light brown sugar. Pour this mixture over the crust.
Step 3: Bake for 35 minutes until the apples are tender and the crust is golden. Let cool slightly, then drizzle with 1/2 cup caramel sauce. Chill for 1 hour before slicing into bars.
