These apple oatmeal muffins are a comforting treat that brings the warmth of cinnamon and the natural sweetness of crisp apples into every bite. They combine hearty rolled oats with tender chunks of Honeycrisp apples, making them a wholesome choice for breakfast or a snack, especially when you want something a little cozy and satisfying without much fuss. This recipe has always been a favorite in my family, especially after that apple picking day that filled the kitchen with autumn scents and left us craving these muffins every weekend.
I first made these muffins after a day at the orchard and the smell of cinnamon and baked apples still brings back that happy memory. Now they are a regular weekend request from everyone at home.
Ingredients
- Rolled oats: One cup old fashioned rolled oats soaked in milk to create a soft, moist texture
- Whole milk: One cup whole milk which hydrates the oats and adds richness
- All purpose flour: One and a half cups all purpose flour for that classic tender crumb choose unbleached for best flavor
- Baking powder: One teaspoon baking powder providing lift to keep muffins light
- Baking soda: Half a teaspoon baking soda balancing acidity and aiding in rise
- Salt: Half a teaspoon salt enhancing flavor throughout
- Ground cinnamon: One and a half teaspoons ground cinnamon lending warm spice essential to the recipe
- Ground nutmeg: Half a teaspoon ground nutmeg adding subtle depth and spice complexity
- Brown sugar: Half a cup packed brown sugar for natural sweetness and moistness
- Egg: One large egg supplying structure and richness
- Vegetable oil: One third cup vegetable oil keeping the muffins tender and moist without overpowering
- Vanilla extract: One teaspoon pure vanilla extract elevating flavor with sweet aromatic notes
- Honeycrisp apples: Two medium Honeycrisp apples peeled and finely chopped for bursts of juicy sweetness and texture pick firm apples to hold their shape well
Instructions
- Soak oats in milk:
- In a medium bowl, combine the rolled oats and whole milk and stir lightly. Let them sit for at least fifteen minutes to allow the oats to fully absorb the liquid. This step softens the oats and helps keep the muffins moist.
- Combine dry ingredients:
- In a large bowl, whisk together the all purpose flour, baking powder, baking soda, salt, cinnamon, nutmeg, and brown sugar. Whisk until everything is well blended and no lumps remain. This helps ensure even distribution of leavening agents and spice.
- Mix wet ingredients:
- In a separate bowl, beat the egg lightly until combined. Add the vegetable oil and vanilla extract, whisking together until smooth and homogenous.
- Bring the batter together:
- Pour the soaked oat mixture and the wet ingredients into the bowl with the dry ingredients. Fold gently using a spatula just until no dry streaks remain. Avoid overmixing since excess gluten formation can make the muffins tough.
- Add apples:
- Fold in the finely chopped Honeycrisp apples, ensuring the pieces are evenly dispersed throughout the batter to deliver bursts of apple flavor in every bite.
- Portion and bake:
- Divide the batter evenly into a twelve cup muffin pan lined with paper liners or greased well. Bake at 375 degrees Fahrenheit (190 degrees Celsius) for eighteen to twenty two minutes. The muffins are done when a toothpick inserted in the center comes out clean with no wet batter attached.
- Cool and enjoy:
- Allow the muffins to cool in the pan for five minutes, then transfer them to a wire rack to cool completely or enjoy warm. These muffins taste great fresh or at room temperature.

The apples really steal the show here I love using Honeycrisp because they have the perfect balance of sweetness and tartness and stay pleasantly firm after baking. These muffins always remind me of that afternoon we spent at the orchard, laughing and picking apples straight from the tree, filling our basket with fall’s best bounty.
Storage Tips
Store cooled muffins in an airtight container at room temperature for up to two days or refrigerate for up to five days. To refresh muffins, warm briefly in the microwave or toaster oven. For longer storage, freeze muffins in a ziptop bag or freezer safe container and thaw at room temperature. They reheat beautifully straight from the freezer with only a few minutes in the oven.
Ingredient Substitutions
You can swap vegetable oil for melted coconut oil which adds a gentle tropical nuance and beneficial healthy fats. Use whole wheat flour instead of all purpose to boost fiber and add a rustic nuttiness. Expect a slightly denser texture, but still tender if you mix gently. Try Granny Smith or Pink Lady apples instead of Honeycrisp for a more tart flavor and a slightly firmer bite in the muffins.
Serving Suggestions
These muffins are lovely warm with butter or a drizzle of honey for extra sweetness. Adding toasted walnuts or pecans on top before baking lends a delightful crunch. Pair muffins with a hot spiced tea or coffee for a cozy brunch. They also work wonderfully alongside creamy yogurt or fresh fruit for a balanced breakfast.

Enjoy these muffins warm or frozen for an easy snack. They capture the cozy flavors of autumn in every bite.
