Step 1

Mix the ingredients: Add oats, cinnamon, baking powder and salt to a mixing bowl and stir to combine. Add the milk, applesauce, eggs, maple syrup and vanilla and stir very well to break up the eggs. Fold in apples and pecans.

Step 2

Add to a casserole dish: Lightly grease a 9×13 inch baking dish and spread the oat mixture in it.

Step 3

Chill the dish: Cover the casserole dish (you can use either plastic wrap or even a towel). Chill in the fridge overnight.

Step 4

Bake the dish: The next morning, remove the dish from the fridge. Preheat the oven to 350°F. Bake until set and golden on top, about 35-40 minutes. Rest the casserole dish on a cooling rack for 5-10 minutes, then slice to serve.
