Variations
Make it bite-sized!
It's easy to separate this baked oatmeal into individual portions. But if you want to make it even easier, place your batter into muffin tins. That way, your apple baked oatmeal comes out perfect for on-the-go eating!
This will also cut your baking time down to 25-30 minutes, so make sure to watch them. When they're golden brown, remove them from the oven.
Make It Vegan
To make this recipe vegan, just replace the eggs and milk. Replace each egg with either ¼ cups of applesauce or 1 medium, ripe smashed banana.
Replace the milk with any non-dairy milk. I suggest using coconut milk because of the thickness, richness, and fat content. Though it still has less fat than whole milk, it comes closer than other non-dairy milks and will make your baked oatmeal thicker.
Reduced Sugar
For a lighter version, you can replace the brown sugar, with ¾ cup of applesauce. The final result is much softer, but still delicious!

What are the best apples to bake with?
Really any type of apple will work for this recipe, but some hold up better in the oven than others. You might try using Jonagold, Honeycrisp, Braeburn, or Pink Lady. Each will have a slightly different sweetness and a slightly different crunch and texture. Try out a couple and let me know your favorite!
