These oatmeal muffins are the perfect easy and healthy snack—made without any refined flour or sugar! Ready in just 5 minutes of prep thanks to your blender, they’re naturally sweetened and packed with whole grain goodness.
These oatmeal muffins have become our weekly staple for homemade snacks! Everyone in our family loves them—my toddler eats one every day and my 8 year old grabs them on the go. They use oats instead of flour and they’re naturally sweetened with honey or maple syrup, with a perfect tender crumb that makes them irresistible.
The best part? Everything goes in the blender, so they’re ready for the oven in under 5 minutes! They’re great a quick breakfast, healthy snack, or lunchbox treat slathered with nut butter. Come experience the blender magic!
What you need for oatmeal muffins
My healthy banana muffins recipe has become somewhat legendary—thousands of readers have loved them and I try to make a batch weekly! But sometimes I face a crisis: my 2-year-old wants her muffins and there’s not a single ripe banana in sight. So I’ve been recipe testing for weeks to make a blender muffin without banana. The result? These muffins might be even better than the original! Here are the ingredients you’ll need:
- Old-fashioned rolled oats: The star ingredient that is ground into flour in the blender! Do not substitute steel cut oats: they do not work in the same way. Make sure to use certified gluten-free oats to make this a gluten-free recipe.
- Greek yogurt: This is the moisture hero replacing mashed banana. Full-fat works best for tender muffins, but 2% is fine too.
- Eggs: Provide structure and help the muffins rise. (I have not tried with flax eggs, but feel free to test and let me know!)
- Olive oil: Sounds weird in muffins, but it creates a nice muffin texture and is Mediterranean diet friendly.
- Honey or maple syrup: Natural sweetness that’s kid-approved; maple syrup makes them vegan-friendly.
- Vanilla, cinnamon, salt: This trifecta makes them taste like a warm hug.
5-star reader review
“These muffins are perfectly sweet but not TOO sweet. One of my daughters had TWO for breakfast drizzled with maple almond butter. My other daughter had one with warmed up with peanut butter. 4 thumbs up from these kids!” -Tanvee

Tips for baking
These oatmeal muffins are so simple to bake up. Here are a few tips to keep in mind:
- Use a standard size blender, high speed preferable. Avoid using a small blender: the quantities are too large (we’ve had one explode accidentally!).
- The batter needs 5 minutes to rest and thicken. At first the batter is very liquid, but letting it stand 5 minutes helps. It will still be looser than you typical muffin batter: don’t worry, it will still bake up to be fluffy!
Flavor variations
There are so many ways to mix up this concept of muffins! You can fold in fruit or nuts for different flavor combinations. Here are some ideas:
- Banana: Go to our Healthy Banana Muffins.
- Apple: Fold in 1 cup diced apples or try Healthy Apple Muffins.
- Blueberry: Fold in 1 cup blueberries or try Banana Blueberry Muffins.
- Zucchini: Add grated zucchini: go to Healthy Zucchini Muffins.
- Nuts: Add chopped toasted pecans or walnuts.
Storing leftovers
These muffins last up to 1 week refrigerated. You can also freeze them in a sealed freezer safe container for up to 3 months. They taste great at room temperature or warmed in an air fryer or toasted oven.
A few more serving suggestions
My 2 year old eats these every day! We love eating this gluten free snack warm with a slather of peanut butter or almond butter to make them more filling.
Add a hint more sweetness with a little hint of honey and a few sprinkles of sea salt. The possibilities are endless! We hope you love them as much as we do. Print
