I’ve been on an oatmeal kick lately, trying different recipes and different types of oatmeal. This Amish Baked Oatmeal recipe is my favorite so far! Baking the oatmeal changes the texture of the oatmeal and it tastes more like an oatmeal cookie.
You can make it the night before and pop it in the oven the next morning. It’s super easy and so delicious! My kids prefer cold cereal in the mornings, so I usually make up a batch, cut it into six squares and then freeze the squares and just warm them up in the microwave each morning.

How to Make Amish Baked Oatmeal
Step 1: Preheat your oven. Combine the oats, brown sugar, and ground cinnamon in a baking dish.
Step 2: In a separate bowl, whisk together the milk, egg, and vanilla, and melted butter.
Step 3: Add the milk mixture to the baking dish and fold the ingredients together until the oats are evenly covered in the mixture. Scatter your fruit over the top of the dish and bake uncovered until the oatmeal is set.
Step 4: Allow your baked oatmeal to cool before serving. Slice into squares and enjoy!
Recipe FAQs
Absolutely! Bake it the night before, let it cool completely, then cover and refrigerate. It keeps well for up to 5 days in the fridge.
Yes! Try diced apples, peaches, or any fresh or frozen fruit. Just keep the quantity around 2 cups to maintain the right moisture balance.
Indeed! Cut into portions, wrap individually, and freeze for up to 3 months. Thaw overnight in the fridge and reheat in the microwave.
You can substitute the whole milk with almond milk or oat milk, and replace the butter with melted coconut oil for a dairy-free version.
Microwave individual portions for 30-45 seconds, or until warm. Add a splash of milk if desired for extra moisture.
Expert Tips
- Cool Time: Don’t skip the 15-minute cooling time – it allows the oatmeal to set properly and develop the perfect texture.
- Best Oats: Use old-fashioned oats rather than quick oats for the best texture and structure.
- Frozen Berries: If using frozen berries, add them while still frozen – no need to thaw. You can also use fresh berries!
- Add Crunch: For extra crunch, try sprinkling chopped nuts on top during the last 5 minutes of baking.

Amish Baked Oatmeal
Ingredients
- 2 cups old fashioned oats
- ½ cup brown sugar
- 2 teaspoons ground cinnamon
- 1 ¾ cups whole milk
- 1 large egg
- 1 teaspoon vanilla extract
- 3 tablespoons salted butter melted
- 2 cups frozen mixed berries
Instructions
- Preheat your oven to 350°.
- Combine the oats, brown sugar, and ground cinnamon in an 8×8 inch baking dish.
- In a separate bowl, whisk together the milk, egg, vanilla, and melted butter.
- Add the milk mixture to the baking dish and fold the ingredients together. Ensure that the oats are evenly covered in the milk mixture.
- Scatter your fruit over the top of the dish and bake uncovered for 40 minutes.
- Allow your baked oatmeal to cool for 15 minutes before serving.
- Slice into squares and enjoy!
Notes
- Allowing your baked oatmeal to cool down a little bit helps cook off some extra moisture, which makes the oatmeal easier to slice and serve.
- Make sure you are using old fashioned oats. We found that with quick oats the baked oatmeal was still quite wet after it baked.
- To store your leftover baked oatmeal, allow it to cool down completely. You can either cover the baking dish with tin foil/ plastic wrap or transfer it to an airtight container.
- Other spices you can add to your baked oatmeal include nutmeg and cloves.

My husband will ABSOLUTELY love this! He is a die-hard oatmeal fan, especially with blueberries and cranberries added:)

livestocreate – You could definitely use dried blueberries. I think frozen blueberries would work as well. I've been wanting to try apples and I've also thrown in some raisins. I hope you enjoy it!

I love your idea for freezing it in squares. How easy that would be to bring out for just one person! Thanks! It looks delicious… I wonder if I could get away with dried blueberries instead? Frozen? They are so pricey right now…

Esta avena se ve tan rica. Hablo en serio. Debo probar esto. Es interesante que nosotras dos hayamos pensando en hablar de avena pero la versión tuya es más saludable.
¡Quiero decirte que aún hasta los acentos tu español ha sido perfecto! ¡Qué bien!

I have never heard of anything like this nor had I heard of the steel cut oats until I read about them on Maria's blog the other day. This sounds like a great breakfast and a good alternative to porridge – I am a bit bored of porridge now!!

This looks so good, and I am not an oatmeal girl. Will have to give this one a try!
