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 like apple cinnamon bread and comforting snacks like pumpkin oatmeal bars. And of course, plenty of pie crust and Thanksgiving pies! 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 and this banana 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. If youโ€™ve tried my chocolate chip baked oatmeal cups or these pumpkin baked oatmeal cups, youโ€™re familiar with todayโ€™s recipe and process. They are more solid than oatmeal, but not as cakey as blueberry oatmeal muffins. If you are in the mood for a more traditional muffin, try these healthy apple muffins instead.


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: Unlike applesauce muffins where oats are simply part of the dry ingredients, here the oats are the entire base of the 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. If you enjoy it in your apple pie or apple cinnamon scones, you’ll enjoy it in these oatmeal cups. 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 work โ†’ big 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: See my pumpkin baked oatmeal cups. I swapped applesauce for pumpkin and reduced the milk to make up for extra pumpkin.
  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.

After these are done, keep out your muffin pan and make a batch of savory breakfast egg muffins next! And for even more inspiration, see my complete list of 30+ healthy breakfast recipes.

Description

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!


Ingredients

  • 1 and 1/2 cups (360ml) milk (dairy or nondairy)
  • 2 large eggs*
  • 1/2 cup (120ml)ย pure maple syrup*
  • 1/2 cup (120g) unsweetened applesauce
  • 3 cups (255g) old-fashioned whole rolledย 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 (120g) peeled chopped apple*
  • optional: 1/2 cup (50g) chopped walnuts or pecans
  • optional: coarse sugar for topping


Instructions

  1. Preheat oven to 350ยฐF (177ยฐC). Generously spray a 12-count 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. In a large bowl, whisk all of the ingredients together, except for the apples (and nuts and coarse sugar). Using a spoon or silicone spatula, fold in the apples and nuts (if using). Batter will be a little liquidy. 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 28-30 minutes or until the edges are lightly browned and top appears set. If the tops are browning very quickly, tent a piece of aluminum foil over the muffin pan.
  4. Cool for 5-10 minutes before serving.
  5. Cover leftover oatmeal cups tightly and refrigerate for up to 1 week.

Notes

  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 350ยฐF (177ยฐC) 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. Special Tools (affiliate links): 12-count Muffin Pan | Glass Mixing Bowl | Whisk | Silicone Spatula
  3. 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.
  4. Eggs: Eggs bind the ingredients. If needed, you can replace the eggs with 1/3 cup unsweetened applesauce or mashed banana. I do find the oatmeal cups fall apart a little when replacing the eggs.
  5. Sugar: I recommend pure maple syrup because the flavor is outstanding and the baked oatmeal cups are extra moist. Instead, you can use packed brown sugar, coconut sugar, or honey.
  6. 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.
  7. Apples:ย Use your favorite variety such as Granny Smith, Fuji, or Honeycrisp. You need about 1 medium apple.

    I halved the recipe and it made 9 fantastic muffins! I made them with the intent to give them to my toddler for breakfast, but I ate 2 of them myself while they were fresh. So yummy, will definitely be making again!

      Hi Susan, you could use an 8ร—8 or 9ร—9 inch baking pan. The bake time will be similar to our baked oatmeal recipe.

    Iโ€™m going to hold off on rating until I try one. My kiddo loved the one he had for โ€œdessert.โ€ I made the recipe exactly as written. I baked them until they were lightly browned and seemed done on top. Cooled them in the tin for 10 minutes, but then most of them were very soft and almost damp on the bottom when I took them out. I eventually decided to toast them all (upside down) in our toaster oven to try to firm up the bottoms before storing in fridge and freezer for future breakfasts. Iโ€™m unsure what the texture is meant to be on the bottoms, but think Iโ€™ll cook them more next time??

    The recipe for the Apple Cinn. Oatmeal Cups is one of my family’s favorites.
    I’ve made these many times with mini choc. chips and walnuts. These baked oat cups are worth the make. Too good for words!

    Why did you mention 3 cups of oats for just 12 mini muffins? I was able to bake 24 mini muffins in my 12 muffin tray in 2 batches. Then again, you also mention not to leave batter before baking, which was the case for 2nd batch ๐Ÿ™

      Hi V, I’m sorry for any confusion but this recipe yields 12 standard size muffin cups, using a 12-cup muffin pan.
