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, 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 you’ve tried my chocolate chip baked oatmeal cups or these pumpkin baked oatmeal cups, you’re familiar with today’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!
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 → 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!

Apple Cinnamon Baked Oatmeal Cups Recipe
Ingredients You’ll Need
Instructions
- Preheat oven to 350°F (177°C). 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.
- 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.. If desired, sprinkle the tops with coarse sugar.
- 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.
- Cool for 5-10 minutes before serving.
- Cover leftover oatmeal cups tightly and refrigerate for up to 1 week.
