Preheat oven to 350 degrees. Spray an 8x8 baking dish with non-stick spray.
Add all of the ingredients except for the apples to a mixing bowl and stir well to combine.
Fold in the apples.
Spread mixture into the prepared baking dish and bake for 30 minutes or until a knife comes out mostly clean with just a few moist crumbs.
Spoon into bowls and serve with a pat of butter and drizzle of maple syrup, if desired.

Notes
We normally use 2% or whole milk in this recipe, but whatever you have on hand should work fine. Oatmilk works great, too!You may swap out the cinnamon and nutmeg for 1 tablespoon of apple pie spice, if preferred.
