Ingredients You’ll Need

These ingredients come together in such a beautiful way—apples, oats, and cinnamon make a winning flavor trio that brings out the best each morning. When shopping, I like to pick baking apples that hold their shape, like Granny Smith or Honeycrisp, so your muffins have that lovely texture with every bite.

• All-purpose flour: Provides structure for the muffins; using fresh flour helps keep them light.
• Old-fashioned rolled oats: Adds heartiness and a slightly chewy texture that complements the apples.
• Baking powder and baking soda: Work together to give the muffins a perfect rise.
• Ground cinnamon: The star spice that gives warmth and that classic apple pie vibe.
• Ground nutmeg: Just a touch adds depth to the spice mix.
• Salt: Balances sweetness and enhances all the flavors.
• Unsalted butter: Softened to room temp for creamy batter and rich taste.
• Brown sugar and granulated sugar: The brown sugar adds molasses notes while granulated keeps it light.
• Egg: Holds everything together and adds richness.
• Plain full-fat yogurt: I love using yogurt—it keeps the muffins moist without making them heavy.
• Baking apples, peeled and finely chopped: Fresh apples are key! Their natural sweetness shines here.
• Oat streusel topping ingredients: Brown sugar, oats, flour, butter, and cinnamon combine for that irresistible crunchy top.

Variations

What’s great about this Cinnamon Apple Oatmeal Muffins Recipe is how easy it is to make it your own. I’ve played around with a few tweaks that turned out really well, and you can too! Feel free to swap ingredients or add your favorite nuts or spices to keep things exciting.

• Add some crunch: I’ve tossed in chopped walnuts or pecans before—incredibly tasty and gives a nice texture contrast.
• Make it dairy-free: Swap the butter for coconut oil and use a plant-based yogurt, and you’ll have a delicious dairy-free version.
• Boost the sweetness naturally: Add a handful of raisins or dried cranberries—it adds little bursts of chewy sweetness that complement the apples.
• Spice it up: Beyond cinnamon and nutmeg, a pinch of ground cloves or ginger can deepen the flavor profile if you’re feeling adventurous.

How to Make Cinnamon Apple Oatmeal Muffins Recipe

Step 1: Prep Your Dry Ingredients

This is your base, so whisk together the flour, oats, baking powder, baking soda, cinnamon, nutmeg, and salt in a large bowl. I like to really mix them well here to make sure all those spices and leavening agents are evenly distributed—this means every bite tastes as good as the last. Set this bowl aside for now.

Step 2: Cream Butter and Sugars

In a separate medium bowl, use a hand or stand mixer to beat together the softened butter with both sugars until it’s nice and fluffy—usually about 2 minutes. This step is essential for light muffins, so don’t rush it. The sugar helps incorporate air, making them rise beautifully.

Step 3: Add Egg and Yogurt

Next, add the egg to the butter-sugar mix and beat until it’s fully combined. Then add in the yogurt and mix again until just blended. The yogurt keeps these muffins moist and tender, which is something I learned after a few tries—not to skip it! It makes all the difference.

Step 4: Combine Wet and Dry Ingredients

Pour the wet mixture into the dry ingredients and gently stir with a spatula. You want to combine everything until mostly incorporated—but don’t overmix! The batter will be thick and a bit lumpy, and that’s just perfect.

Step 5: Fold in the Apples

Fold in the finely chopped apples carefully, so they’re evenly distributed without beating the batter too much. This step is crucial because overmixing can make the muffins dense.

Step 6: Prepare Muffin Pan and Add Batter

Line a 12-cup muffin tin with liners or spray with nonstick spray. Use a cookie scoop or spoon to fill each cup about 85% full. Filling them just right helps them bake evenly without spilling over.

Step 7: Make the Oat Streusel Topping

Mix together the topping ingredients in a small bowl—brown sugar, oats, flour, butter, and cinnamon—until crumbly. Sprinkle a generous spoonful on top of each muffin; that crispy topping is what takes these from good to unforgettable.

Step 8: Bake, Cool, and Enjoy

Bake your muffins at 375°F for 20 to 25 minutes. The best test? Insert a toothpick in the center—it should come out clean or with just a few moist crumbs. Once baked, let them cool in the pan for 5 minutes, then transfer to a wire rack to cool completely. This cooling step helps keep the tops crisp and prevents sogginess.

How to Serve Cinnamon Apple Oatmeal Muffins Recipe

Garnishes

I like to keep things simple and sprinkle a light dusting of powdered sugar or a tiny pinch of cinnamon right before serving. If I’m feeling indulgent, a slather of butter or a dollop of maple cream cheese pairs beautifully and adds richness without overpowering the flavors.

Side Dishes

These muffins make a great cozy breakfast or snack, so I often serve them alongside fresh fruit, a hot cup of coffee, or a steaming mug of chai tea. For a heartier morning, they pair wonderfully with scrambled eggs or even a green smoothie for balance.

Creative Ways to Present

For a fall brunch or special occasion, I’ve arranged these muffins in a pretty basket lined with a linen napkin, garnished with small cinnamon sticks and fresh apple slices on the side. It’s a simple touch that makes guests feel like you went the extra mile.

Make Ahead and Storage

Storing Leftovers

I usually keep leftover muffins in an airtight container at room temperature for up to 3 days, but they rarely last that long! If you want them softer, wrap each individually in plastic wrap to lock in moisture.

Freezing

Freezing is a game-changer with this Cinnamon Apple Oatmeal Muffins Recipe. Once completely cooled, I pop them in a freezer-safe bag or container for up to 3 months. When I want a quick breakfast, I just thaw one overnight or use the microwave defrost setting for a couple of minutes.

Reheating

To keep the muffins moist while reheating, I like wrapping one in a damp paper towel and microwaving it for 20-30 seconds. Or, for a crispier top, pop them in a 325°F oven for about 5-7 minutes—just enough to warm through without drying out.
