Step 1

Preheat oven to 425ºF. Coat a nonstick baking sheet with cooking spray.

Step 2

To make filling, peel and core apples; cut each apple into six 1/4-inch-thick slices. In a medium bowl, combine apples, Splenda, cinnamon and nutmeg; toss to combine. Spread apple mixture over prepared baking sheet so apples are mostly in a single layer. Bake for 5 minutes; flip apples with a spatula and bake for 5 minutes more.

Step 3

Meanwhile, combine topping ingredients in a small bowl; mix well. Spread oat mixture over another nonstick baking sheet and bake until lightly browned and crisp, about 2 minutes.

Step 4

To serve, place 6 slices of apple in each of 4 shallow bowls and top each with about 2 tablespoons of oat topping.
