Imagine sinking your teeth into a moist, warmly spiced muffin bursting with tons of apple flavor, carrots, and the sweetness of ripe bananas.

Now, picture an irresistible drizzle of tangy lemon glaze on top. That’s the kind of breakfast that makes busy mornings just a bit brighter, don’t you think?

I make them whenever apple season rolls around but honestly, if we have a busy week ahead, I’ll make these apple oat muffins along with crock pot brown rice, falafel, and roasted beet salad, as part of my meal prep on Sunday no matter what time of year.

They are super filling, make an excellent quick breakfast or after school snack, and my whole family loves them, even the kids, which getting them to eat carrots for breakfast is no small achievement.

Spooning the muffin batter into the tin you are going to be thinking to yourself, there is no way these are going to work. The batter is ridiculously thick and dry and it appears as if the shreds of apple and carrot are held together by a thin web.

But magic happens in the oven and they emerge moist, slightly chewy and incredibly flavorful, considering there is hardly any fat in them whatsoever. This is a muffin you won’t regret eating twenty minutes after licking the last crumb off your plate.

Don’t be shy—indulge in one, two, or maybe even three—they’re that good. My passion is helping you become a happier, more confident home cook, so get ready to bake up some happiness!

Packed with Goodness, Not Guilt

These healthy apple muffins are more than just a delicious treat. They’re a powerhouse of nutrition! Here’s what makes them such a great recipe:

  • Fiber-filled: Oats, apples, carrots, and bananas team up for a fiber boost, keeping you satisfied. Just like my oatmeal hazelnut chocolate chip cookies, but, you know, healthier.
  • Naturally Sweet, Dairy-Free: They do contain some refined sugar but the ripe bananas and apples add sweetness and moisture, making these muffins dairy-free and naturally delicious.
  • Minimal Fat: The healthy fat of olive oil and 1 egg are the only fatty addition to these muffins making them surprisingly light.


All the ingredients to make the apple muffins including oatmeal and more.
  • All purpose flour
  • Light brown sugar. Add warm sweetness similar in flavor to this pear cranberry crisp.
  • Baking soda
  • Baking powder
  • Nutmeg or ground cinnamon
  • Kosher salt
  • Old fashioned rolled oats. I don’t recommend using quick oats
  • Olive oil or melted coconut oil or unsalted butter if you don’t mind it not being dairy free.
  • Large egg at room temperature
  • Almond milk or refrigerated coconut milk (not canned).
  • Carrots. If you bought a bag of carrots to make my German goulash soup or my chicken cacciatore you can use the last two here!
  • Apple. If you like large pieces of apple in every bite, feel free to mix in chopped apple instead of grated apples.
  • Banana
  • Lemons
  • Powdered sugar

How To Make This Recipe (Step-by-Step Instructions)

step one

Mix dry ingredients. Heat oven to 400°F and line a muffin pan with muffin liners. No need for a stand mixer, simply combine flour, brown sugar, 1/2 tsp baking soda, baking powder, nutmeg, salt, and oats in a large mixing bowl.

step three

Bake. Scoop into muffin cups and fill all the way to the top and bake for 20-25 minutes, or until a toothpick inserted comes out clean. Allow the muffins to cool for 5 minutes in the muffin tin, then transfer to a wire rack to continue cooling.

Make glaze. Whisk together powdered sugar, lemon zest, and the lemon juice in a medium bowl until smooth. By the way, this glaze is amazing on my soft pumpkin cookies too.

step five

Serve! Drizzle glaze over the muffins and enjoy. Muffins stay fresh in an airtight container at room temperature for a few days, then transfer to the fridge for up to 1 week. For longer storage, freeze muffins for up to 3 months. Allow to thaw overnight in the refrigerator, then bring to room temperature or warm up in the microwave if desired.

Oatmeal Apple Muffins FAQ’s

Can I substitute the all-purpose flour for gluten free or whole wheat flour? Yes, you can try substituting with a 1:1 gluten-free baking flour blend or whole wheat pastry flour. The texture might be slightly different.

Do I have to use bananas? The banana adds sweetness and moisture to this muffin recipe, but if preferred, you can substitute with an equal amount of unsweetened applesauce.

What are the best apples to use for baking? If I’m making something with lots of apples like apple pie, I use a combination of sweet (Gala) and tart (Granny Smith) apples. But with this recipe we only need one so I like to use an apple that is a little bit tart and a little bit sweet like a Pink Lady apple.
