Creating the No-Bake Oatmeal Apple Pie Lasagna is simple and enjoyable. Follow these straightforward steps to bring this dessert to life:

1. Prepare Apples: In a mixing bowl, combine the chopped apples with cinnamon and a drizzle of maple syrup or honey (if using). Set aside.
2. Mix Cream Cheese Layer: In another bowl, beat together the softened cream cheese, Greek yogurt (or sour cream), powdered sugar, and vanilla extract until smooth and creamy.
3. Layer Oats: Spread half of the rolled oats evenly in the bottom of a rectangular dish.
4. Add Apples: Sprinkle half of the apple mixture over the oats, spreading it evenly.
5. Cream Cheese Layer: Spread half of the cream cheese mixture on top of the apples, ensuring to cover them completely.
6. Repeat Layers: Add the second layer of the remaining oats, followed by the rest of the apple mixture, and top with the remaining cream cheese layer.
7. Garnish (Optional): If desired, sprinkle chopped walnuts or pecans on top for added texture and flavor.
8. Chill the Lasagna: Cover the dish with plastic wrap and refrigerate for at least 2-3 hours, or overnight for best results.
9. Serve: Once chilled, slice into squares and serve with whipped cream or your favorite topping.
