Amish Style Apple Cinnamon Baked Oatmeal

This style of baked oatmeal is a favorite breakfast among the Amish and Mennonites. This baked oatmeal is made with rolled oats, cubed apples (no apple sauce) and cinnamon for a delicious breakfast treat. My favorite part about this baked oatmeal is that it can be prepped the night before and left overnight in the refrigerator, for a breakfast that is ready to be baked while you get ready for the day. Amish style baked oatmeal is my go-to for Sunday mornings or mornings when we are traveling and need something quick and filling before we head out the door.

If refrigerating the baked oatmeal overnight, you can wait to bake the oatmeal until the morning. When refrigerating the baked oatmeal overnight, I like to add an extra tablespoon or two of milk to keep the oatmeal moist. 
You can also bake the oatmeal the night before, cool it to room temp and then refrigerate it overnight to pop into the microwave it in the morning.

Equipment for the Amish style apple cinnamon baked oatmeal:

  • Baking dish A 9 by 13 inch baking dish is needed to bake the oatmeal in, I prefer to use a glass baking dish because it makes checking the sides and bottom of the baked oatmeal easier.
  • Mixing bowl You will need a large mixing bowl for combining the oatmeal mixture and a smaller mixing bowl for combining the apple cinnamon mixture.
  • Spatula A spatula is useful for both scraping out the bowl and spreading the oatmeal out evenly in the baking dish.
  • Measuring cups I personally prefer to use stainless steel measuring cups, because they have been so durable for me.

Ingredients needed for this Amish style apple cinnamon baked oatmeal: Milk, vanilla extract (optional), butter, eggs, salt, baking powder, oats, brown sugar and apple cinnamon mixture (apples, cinnamon brown sugar).

Step 1: Combine the eggs, 3/4 cup brown sugar, melted butter, baking powder, and salt. Mix well, then whisk in milk and vanilla.

Note for combining the baking powder and salt into the wet ingredients first:

Be sure to combine the salt and baking powder with the wet ingredients before adding oats and apples to the mixture. This ensures the baking powder is more evenly distributed into the baked oatmeal.

Step 2: Combine the apple chunks with cinnamon and the remaining 1/4 cup brown sugar, then add to the wet mixture along with the 3 cups rolled oats. Fold gently to combine.

Does the cinnamon from the apples mix into the oatmeal filling?

As you fold the apple cinnamon mixture into the baked oatmeal, some of the cinnamon and brown sugar will incorporate into the oatmeal mixture.

Step 3: Pour the oatmeal mixture into a greased 9 by 13 inch pan, then bake immediately or refrigerate overnight.


If your oven has a delay start setting you can set it to preheat in the morning, so that you can get an extra 10-15 minutes of sleep!

Step 3 continued: Bake until golden and set in the center, then enjoy with milk and additional fruit or raisins (optional).
