Apple Cinnamon Baked Oatmeal Cups

Using a few simple ingredients and 1 bowl, throw these healthy apple cinnamon baked oatmeal cups in the oven. They’re ready in about 30 minutes. My whole family, toddler included, loves them. Try the other flavors listed, too!

These Baked Oatmeal Cups Are:

  • Refined sugar free (no added refined sugar)
  • Definitely healthy
  • Easy & quick
  • Soft-baked & moist in the center
  • Chewy on top
  • Garnished with crunchy coarse sugar
  • Dairy free if using dairy free milk
  • Gluten free if using certified GF oats

The fall season may mean saying GOODBYE to pool days, but it also means giving a big HELLO to favorite seasonal flavors and comforting healthy snacks. (Whole wheat mini pumpkin muffins!) With fall flavors on my mind, I tested out a muffin version of my baked oatmeal. These oatmeal cups are a little more solid and sturdy than the creamy baked oatmeal, so they’re awesome as a portable breakfast or snack. And if you’re still in summer mode (I totally am!), swap the apples for blueberries or strawberries. These were so good!

Are They Oatmeal? Are They Muffins?

Yes and yes. More solid than oatmeal, but not as cakey as blueberry oatmeal muffins. 🙂

Ingredients in Baked Oatmeal Cups

You need 11 simple ingredients for my baked oatmeal cups. Each is important!

  1. Milk: Milk softens the oats and keeps the centers moist. I reduced the amount from my baked oatmeal so the oatmeal muffins are a little more solid.
  2. Eggs: Eggs provide protein and structure.
  3. Maple Syrup: Pure maple syrup sweetens and flavors these baked oatmeal cups. If needed, honey is a wonderful substitute.
  4. Unsweetened Applesauce: Applesauce adds flavor and takes the place of butter or oil. I love using applesauce to replace all or some oil in certain baked goods, like my morning glory muffins.
  5. Oats: Oats are the base of the entire recipe. Old-fashioned whole rolled oats are the best and also what I recommend for oatmeal raisin cookies. Quick oats work, but the centers of the oatmeal cups aren’t as moist. Steel cut oats require extra prep, see recipe note.
  6. Baking Powder: Baking powder prevents the oatmeal cups from tasting dense.
  7. Cinnamon & Nutmeg: Can you eat an apple baked good without either?! If you have any in the house, feel free to use apple pie spice instead.
  8. Vanilla Extract: Vanilla extract adds flavor.
  9. Salt: Salt adds flavor.
  10. Apples: Grab your favorite apple variety, peel it, and chop it into bite-size pieces. I usually use Granny Smith or Honeycrisp. Any variety works. No need to pre-cook the apples before adding to the oat mixture.

Baker’s Tip: The batter is liquid-y. When you’re dividing the batter between the muffin cups, make sure you have both liquid AND oats/apples in each. Spoon batter all the way to the top of each. The recipe yields 12 apple cinnamon baked oatmeal cups.

1 Bowl, No Mixer Recipe

Besides taking approximately 2 seconds to prep, these oatmeal cups only require 1 bowl. No need to break out your mixer– instead, fold the mixture together by hand. They’re done in about 25 minutes. It’s practically shocking how easy these are.

Little workbig reward.

I usually prep these or regular baked oatmeal in the beginning of the week, then refrigerate for quick breakfasts or snacks. Reheat in the microwave for a few seconds to warm them up. They freeze and thaw beautifully, too!

Who doesn’t crave a little variety?! Instead of apple, try any of these flavors. 🙂

Flavors & Add-Ins

  1. Pumpkin: Swap the applesauce for pumpkin puree (not pumpkin pie filling). Leave out nutmeg. Leave in cinnamon. Add 1 teaspoon pumpkin pie spice.
  2. Blueberry: Leave out the nutmeg, reduce cinnamon to 1 teaspoon, and swap apples for fresh or frozen blueberries. No need to thaw.
  3. Banana: Swap the applesauce for mashed banana.
  4. Chocolate Chip: Swap apples for chocolate chips. If desired, leave out the nutmeg.
  5. Peanut Butter / Nut Butter: Reduce applesauce to 1/3 cup. Add 1/2 cup nut butter. Leave out apples and nutmeg, if desired.

Baked Apple Cinnamon Oatmeal Cups

  • Author: Sally
  • Prep Time: 5 minutes
  • Cook Time: 25 minutes
  • Total Time: 35 minutes
  • Yield: 12 cups
  • Category: Breakfast
  • Method: Baking
  • Cuisine: American


Using a few simple ingredients and 1 bowl, throw together these healthy apple cinnamon baked oatmeal cups. They’re soft and moist inside with chewy tops and plenty of flavor. Make them ahead and enjoy all week long!


  • 1 and 1/2 cups (360ml) milk (dairy or nondairy)
  • 2 large eggs*
  • 1/2 cup (120ml) pure maple syrup*
  • 1/2 cup (120g) unsweetened applesauce
  • 3 cups (240g) old-fashioned whole oats*
  • 1 teaspoon baking powder
  • 1 and 1/2 teaspoons ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1/2 teaspoon pure vanilla extract
  • 1/4 teaspoon salt
  • 1 heaping cup peeled chopped apple*
  • optional: 1/2 cup (50g) chopped walnuts or pecans
  • optional: coarse sugar for topping


  1. Preheat oven to 350°F (177°C). Generously spray a muffin pan with nonstick spray. If using muffin liners, spray them with nonstick spray. The oatmeal cups stick to the liners a bit regardless, so I recommend skipping them.
  2. Whisk all of the ingredients together, except for the apples (and nuts and coarse sugar), in 1 large bowl. Using a spoon or rubber spatula, fold in the apples and nuts (if using). Batter will be a little liquid-y. Spoon batter evenly into muffin cups, making sure both the oats/apples and liquid are in each. Fill all the way to the top. See photo above. If desired, sprinkle the tops with coarse sugar.
  3. Bake for 25-30 minutes or until the edges are lightly browned and top appears set. If the tops appear to brown very quickly, tent a piece of aluminum foil on top.
  4. Cool for 5 minutes before serving. Cover leftover oatmeal cups tightly and refrigerate for up to 1 week.


  1. Make Ahead & Freezing Instructions: Bake the oatmeal cups, cool completely, and store in the refrigerator all week for easy breakfasts. Reheat in the microwave or bake in a 350°F (177°C) oven for 5-6 minutes. To freeze, bake and cool oatmeal cups. Cover tightly and freeze for up to 3 months. Thaw in the refrigerator or at room temperature. Warm to your liking.
  2. Don’t: Do not make oatmeal batter ahead of time. The oats will soak up all the liquid! Whisk it all together, then bake right away. See make ahead instructions above for alternative.
  3. Eggs: Eggs bind the ingredients and add wonderful flavor. If needed, you can replace the eggs with 1/3 cup unsweetened applesauce or mashed banana.
  4. Sugar: I recommend pure maple syrup because the flavor is outstanding and the baked oatmeal is extra moist! Instead, you can use packed brown sugar, coconut sugar, or honey.
  5. Oats: Whole oats give you the best texture. You can use quick oats instead, but they soak up more moisture so the centers won’t be as moist. If using steel-cut oats, soak the oats in the milk for 30 minutes, then stir in the rest of the ingredients. Add a few extra minutes to the bake time. The oatmeal cups are best with whole oats.
  6. Apples: Use your favorite variety such as Granny Smith, Fuji, or Honeycrisp. You need about 1 medium apple.

  1. I made these for a friend and they almost didn’t make it to her! My husband and preschooler had to be promised their own batch!
    Fun challenge suggestion! Now that Noelle’s a little older how about posting a homemade play dough recipe and challenging everyone to create something? It’s more crafty than sweet but it could be edible…

    1. I’m thrilled that you and your family enjoyed these so much! We have made play dough before and yes, it is fun!

  2. I made this with fresh raspberries and reduced the maple syrup to 1/4 cup or 60 grams, it was super tasty. Next time I will bake my cups a little longer. Excited to eat the leftovers tomorrow for breakfast! Definitely a keeper.

    1. YUM! These would be delicious with raspberries- thanks for your positive feedback, Jenny 🙂

  3. Siobhan Clyburn says:

    Finally something has made my 6 year old son eat oatmeal. I am an oat fanatic and he hasn’t liked oatmeal since he was a baby, but he ate this and he liked it. Another slam dunk recipe. Thanks Sally.

  4. I made these on Sunday and loved them! Can’t wait to make them with blueberries or chocolate chips!
    Another keeper!

  5. Sabrina Dias says:

    Is there a substitute for nutmeg or would leaving it out make a big difference?

    1. Hi Sabrina, If you don’t have nutmeg you can increase the amount of cinnamon, or use pumpkin pie spice or apple pie spice!

  6. These are so good!! I feel healthy eating them so that’s a big plus.
    I added 1/4 cup of ground flax seed to mine.

    1. These are delicious! Instead of putting them in a cupcake pan, I used a glass 9×9 and baked it for about 45 minutes. I also used 3/8 cup maple syrup instead of 1/2 cup, and it still came out great! Highly recommend!

  7. Hi Sally,

    Thank you for always taking the time to answer our questions. As usual, I have a butter question.

    I noticed that this recipe is very similar to your 1 Bowl Baked Oatmeal, which has 1/4 cup melted butter in the recipe. Would that amount of melted butter work in this recipe?

    Thank you for such a great site and delicious recipes that always work like a charm!


    1. Hi Shannon! I actually didn’t find the butter necessary in these. I cut down on the wet ingredients as a whole because these should be a little more sturdy than the baked oatmeal casserole.

  8. Hi Sally! I’m new to your site but I’m all in! Recently ordered & received your “Baking Addiction” updated recipe book & it is awesome! Full of so many easy to follow instructions, tips & scrumptious recipes! I feel I have found a treasure. Today I baked the subject apple cinn oatmeal cups, exactly as you instructed. I used non stick cupcake pan & in addition sprayed it as you advised. They came out perfect. Delicious! Picky hubby loved them. Thank you Sally!

    1. Welcome to the site, Tia!! I’m so glad you found your way here and are enjoying it so much!!!

  9. Hi Sally,

    Wow! I will be trying this soon definitely. Can it also be baked in a casserole dish or half sheet pans, so they can just be cut into bars?
    Thank you! I really enjoyed all the recipes I’ve tried before!


    1. Hi Suzi, Yes you can bake this in a pan and cut into bars. Enjoy!

  10. I’m not big on apple but loved these. Planning chocolate chip next

  11. For the pumpkin version, can I take out the apples?

    1. Yes, absolutely!

  12. Hi Sally. I would like to replace the applesauce with apple butter. I found an organic brand with just two ingredients….apples and a bit of apple juice concentrate. I made your Apple Cinnamon Oatmeal cookies which were a hit even though they were flat and sticky which I’m sure was a result of the applesauce I used. Can the apple butter be substituted in both recipes?

    1. Hi Ann! Happy to help. You can use some apple butter in the two recipes, but be careful because apple butter is sweet. You may need to adjust the sugar in the cookies and these oatmeal cups.

      1. Thank you Sally. I didn’t think of reducing the sugar. I’m going to try to make the cups this week and will let you know how they turn out. Thanks again for all your great recipes and sharing your knowledge with us.

      2. Hi Sally. I made these yesterday using the apple butter and dried apples. They’re delicious. My son-in-law is taking some to work for breakfast. I did not adjust the sugar in the cups but plan to when I make the oatmeal cookies. Thank you so much for this great recipe.

  13. My new fav breakfast! I’ve made blueberry and apple so far and both are great! Question though, I was looking at your baked oatmeal recipe and it uses 1/4c (60g) of applesauce and this recipe used 1/2c (60g) applesauce. Which is correct for this recipe – the 1/2 cup or 60g?

    1. Hi Carly! This requires 1/2 cup applesauce which is 120g– sorry about that!

  14. I made this to take on our annual girls weekend. I made the blueberry version. Very, very good. Not a muffin, but actually baked oatmeal in a cup version. Traveled well. I am going to make these again to eat in my morning commute.

  15. Just whip these up, they’re fantastic!! My husband is sensitive to eggs, dairy and flour, I used coconut milk and mashed banana they turned out perfect. Can’t wait to try your baked oatmeal recipe!!

  16. Can you use homemade applesauce? Or do you need the binders that are in store bought? Thank you!

    1. Hi Tina, You can use homemade! Enjoy!

  17. These are so good! They’re now in direct competition with your one-bowl baked oatmeal recipe in my health breakfast rotation :-). Thanks for the recipe!

  18. These are delicious! I made exactly as written. They are great warmed in the microwave and topped with berries. Can’t wait to try other variations!

  19. I needed these in my life. I made the recipe as directed for apple and added pecans. I never have time to eat in the morning, but now a warm breakfast is ready to go from the fridge with just a few seconds in the microwave, and it’s healthy! Mine took a little longer to bake, but I think that was more my oven than the recipe. Thank you so much for this one!

  20. I made these the other day, great little breakfast treat and so easy to make. I added a half a cup of raisins to the recipe-so happy I did. Will definitely make these again.

  21. How much honey should we use when replacing the maple sugar?

    1. Same amount as maple syrup (1/2 cup).

  22. These were very easy to make and took a little longer to bake. Texture good and happy to have a healthy fast breakfast option. However we found the taste to be a little bland. I double checked the spices and was spot on. Do you have any suggestions for adding more flavor? Can I just double the spices?

    1. Hi Julie, You can certainly increase the spices to suit your taste!

  23. These are fantastic. I love on the go breakfast. I am preggo and these have been fantastic. I usually reheat them in the morning and add some banana on top. These are perfect =]

  24. Big fan of these as a healthy breakfast for my 18 month old (and myself!). I added Trader Joe’s mixed nut butter and they are prefect. I only used half the syrup and they are still plenty sweet. I let the whole mixture sit for about 20 minutes before I put them in the pan so that the oats would soak up the milk and I wouldn’t have to worry about trying to get the right ratio of dry to wet ingredients in each cup. Thanks for the recipe!

  25. These are so delicious! I’ve made them many times and every time they are a hit. Thank you for such a delicious recipe! For the different varieties, you mention replacing the applesauce. Should I take out the apples, too, or did you keep them in when you were testing the different flavors. Thank you!

    1. I’m so glad these have been such a hit! It’s really up to you if you want to keep the chopped apples or not – this recipe is so versatile. In the pink box above with flavor ideas I did not keep the apples in most of them, but they could certainly work in some, especially the banana and blueberry (use half apple half blueberries)… the combinations are endless 🙂

  26. I made this recipe this morning. Very easy to make, but unfortunately the insides of my cups are super soggy and undefined! Do you think it would be a matter of cooking them for longer, or should I reduce the amount of wet ingredients?

    1. It sounds like they just weren’t cooked long enough. Try adding a couple of minutes to your bake time and that should help!

  27. Do you think I could make this into an oatmeal bake in a 8 by 8 pan?

    1. Hi Kate! Sure can. 8×8 or 9×9 baking pan would be best. This is similar to my baked oatmeal recipe.

  28. perfect thanks!

  29. Hi,
    If I am replacing the egg in this recipe, would I add 1/3 cup of applesauce in addition to the applesauce already required in the recipe?

    1. Yes, exactly.

  30. Hi Sally! Do you think adding protein powder to this recipe would work? It looks delicious, I’d just love a little extra protein in there 🙂

    1. I don’t have any experience baking with protein powder but you can certainly try it. Let me know how it turns out!
