Preheat oven to 325. Prep your baking dish for nonstick.
Arrange the sliced apples in your prepped pan/dish/plate as you would like them to be presented. Divide the melted butter into tow bowls or measure cups that you can work in.Combine together your sugar alternative and brown sugar alternative. Whisk this into one of the melted butter cups/bowls that you just divided
Pour and brush this butter sugar alternative mixture over the apples. Bake this for about 25-30 minutes, apples should somewhat brown and become soft. Meanwhile, combine together your remaining ingredients.
Please see recipe post for important details.
As mentioned, you will need rolled oats, which you can easily find online. I like to use a combination of apples as Granny Smith, Golden Delicious, Gala, etc.
