Low calorie muffins are one of my favorite snacks! It’s no secret I’m a muffin lover and if you’ve been following for awhile, there’s a good chance you’ve tried a muffin or two from this blog. They’re an easy way to enjoy a perfectly portioned treat without going overboard.

Balancing lighter treats with healthy food is something I promote with my weight loss clients. In fact, many of them are surprised when I tell them not to restrict foods they love. When you restrict, you’re more likely to binge, feel like a failure and throw in the towel.

These banana and oat muffins that are healthy are an example of how you can have your treats and lose weight too! Love the flavor combination? Then you’ve got to try my Chocolate Banana Oat Bread next!

Ingredients for Low Calorie Banana Muffins

Ingredients to make healthy oat muffins on the table.
  • Gluten Free Rolled Oats: This keeps them flourless. Oatmeal is naturally gluten-free but often it’s processed in the same facilities as wheat so there is some cross-contamination. Make sure you choose oatmeal marked gluten-free.
  • Bananas: Make sure you have very ripe bananas. The sweetness of bananas increases as they ripen so the riper they are the more sweetness they give the muffins.
  • Greek Yogurt: Use non-fat yogurt for the lowest calories and fat content. It adds protein to the muffins and works to balance the healthy carbs in the muffins.
  • Eggs: Add moisture to the muffin batter as well as helping to hold the muffins together.
  • Leaveners: We’re using a combination of baking powder and baking soda to give these healthy banana muffins with oats the right amount of lift.
  • Vanilla Extract: The secret to adding natural sweetness and warmth to baked goods. Use pure vanilla extract for the best flavor.
  • Optional Ingredients: You can add a tablespoon or two of honey or maple syrup if you want your healthy oatmeal muffins a bit sweeter. Also chocolate chips are optional if you want to add them to make a healthy gluten-free chocolate muffins.

Recipe FAQs

Can I freeze these banana oat muffins?

Yes, of course! I love meal prepping two batches at a time so I can freeze a batch for future snacking. Hope you enjoy them!

Can I replace the oats with regular flour?

No, this recipe is developed using oats. You will not get the same results with regular flour if you use this method to make them. I would recommend you find an alternate recipe that’s been written using all-purpose or whole wheat flour.

Can I replace the oats in the oat muffins with oat flour?

Yes, you can replace the oats with oat flour. I have not tested the recipe yet with oat flour so I do not know the exact quantity. I would start slightly less than the amount of oats if you want to try it!

Yes, if you are not gluten free you can use regular oats.

  1. Glutenhatesme says:

    I followed the recipe but didn’t add chocolate chips or honey/maple syrup. I had a thick batter. They looked beautiful when they came out of the oven, then slowly they started to deflate…….what did I do wrong?

    1. Megan says:

      Over mixing the batter is the most common reason for this. Expired baking powder/baking soda as well.

  2. Mercedes says:

    You mentioned to add everything in the blender except the choco chips. However it is too thick to blend/mix. Am I doing something wrong?

    1. Megan says:

      Are you using the same ingredients – oats, yogurt, bananas, baking soda, baking powder, eggs and vanilla extract? That should not be too thick to blend.

  3. Rachel says:

    I made the recipe as written & it was delicious. Have made it a few times now & my family loves these muffins.

  4. Valarie says:

    These are perfectly delicious just as the recipe is written! I love the non fat yogurt and no added fats is an extra treat while trying to be heart healthy.

    1. Megan says:

      Glad you enjoyed them!

  5. asiana pfeiffer says:

    how many calories would the muffins be if i made a mini batch with the same ingredients

    1. Megan says:

      You can either create the recipe in a food tracking app like LoseIT and adjust the serving number to get that or you can multiply the calories by 9 to get the total calories in the recipe then divide by the number of mini muffins you plan to make to get an estimate per muffin.

  6. Jane says:

    Hi – Can I use oat flour instead of rolled oats? If so, would it be the same quantity?

    1. Megan says:

      You should be able to. I have not tested it myself so I do not know the exact quantity. It will be slightly less than the amount of rolled oats.
