This delightful Greek yogurt banana muffins recipe hit all the marks. A subtle sweetness from natural sources like pure maple syrup, coconut sugar, and of course the deliciousness of the ripe, mashed bananas. Greek yogurt helps to make them soft and pillowy and obviously walnuts for the crunch factor.

Ingredients You Will Need:

All of these ingredients are pretty common pantry items.

  • oats – certified gluten-free for those with allergies
  • Greek yogurt
  • bananas – ripe as possible
  • eggs
  • milk
  • coconut sugar
  • baking powder
  • baking soda
  • walnuts

The only thing you need to prepare beforehand with these healthy banana muffins is to have super ripe bananas. Considering this recipe is lower in sugar than others, you need the added sweetness from the ripe bananas.

Look at these beauties!

To keep things wheat/gluten-free I make my own gluten-free oat flour in the blender.

All you need is certified gluten-free oats and the rest is child’s play. You can add fiber and nutrition to your pan of muffins.

Instructions to Make This Recipe:

First, add the oats to the blender.

Second, blend the oats into flour.

Easy peasy!

Next, mix together the batter and stir in the nuts. Finally, pour into prepared muffin cups that are lined with parchment liners or use a coconut oil cooking spray.

Finally, bake until a toothpick comes out clean, about 25 minutes to half an hour. Let them cool on a wire rack.

Now we have healthy banana muffins with oats. So much better than processed flour and it bakes up beautifully!


How can I get my muffins to rise more? A great tip I’ve learned is to get your muffins into the oven quickly. Once the wet ingredients are mixed in with the baking soda and baking powder they activate the leavening agent. The faster they start to heat the more your muffins will rise.

What does adding yogurt to muffins do? The creaminess definitely helps keep your muffins moist and the tanginess is reminiscent of that old-fashioned donut flavor. Yum! Yogurt also adds protein.

Serving Suggestions and Substitutions:

  • Serve warm on it own or add some butter, jam or preserves. I love anything strawberry with the banana flavor.
  • Add chocolate chips.
  • Substitute the oat flour for whole wheat flour
  • Add a teaspoon vanilla and a pinch of salt for added flavor.
  • Use brown sugar instead of coconut sugar.

  1. About bananas. Sometimes I forget about them while waiting until they are ready for baking. Can I still use them if they are really black? Sometimes they seem almost liquid inside. I am sad to throw them away.

    1. A tip I use is to peel and freeze the bananas before they have turned completely. I have some in the freezer right now! Then just thaw them before you want to use them in a recipe.

    I love working with oat flour, I blend up a big batch and store it as flour. Do you know how much flour you get after blending down the 2 cups of oats? Thanks.

    1. Hmmm … you know, I’m not sure. I just blend it up right before using it. I’d estimate about a cup or so but really I’m not 100%. Good point, though! I will remember to measure it post blending next time. Thanks Amy. 🙂
