Banana Oat muffins

These banana oat muffins really are wonderful. I used to make this recipe with plain rolled oats. Recently though, I’ve discovered how to make my own oat flour. It makes the texture of the muffin much fluffier. And even better, it’s palatable for those picky eaters who claim they don’t like oatmeal. I may be biased but I believe these are the best dairy free banana muffins I’ve ever had. This recipe for banana oat muffins is perfect for a quick breakfast made the night before or a healthy snack. They are not overly sweet and can be made suagr free and whole wheat.

Banana Oat Muffins

Prep Time10 mins
Cook Time16 mins
Course: breads, Breakfast, Morning, Snack
Cuisine: American
Keyword: banana, banana muffins, Banana Oat Muffins, Chocolate, Chocolate Chip, Dairy free, Oatmeal, Oats
Servings: 12 muffins


  • Large mixing bowl
  • Medium sized mixing bowl
  • Mixing spoon
  • Measuring cups and spoons
  • Muffin tin


Mix dry ingredients together:

  • 1 ½ cups white flour or whole wheat*
  • 1 cup oat flour** or regular rolled oats
  • ¼ cup brown sugar
  • 2 tsp baking powder
  • ½ tsp baking soda
  • ½ tsp salt

Mix together liquid ingredients:

  • 2 eggs
  • ¼ cup olive oil or any other oil you use in baking
  • ¼ cup of coconut or almond milk sub any milk
  • 2 overripe bananas mashed about one cup


  • chocolate chips dairy free to sprinkle



  • Preheat the oven to 350 F.
  • In a large bowl mix together the dry ingredients.
  • In a medium sized bowl mix together the liquid ingredients.
  • Add the liquid ingredients to the dry and fold together to combine. There may still be little spots of flour in some places and that is good because you want it a bit lumpy looking. You don’t want to over mix them.
  • Spoon into paper lined muffin tins. Bake at 350 F for 16 minutes or until a toothpick inserted in the center comes out clean. The tops of the muffins will spring back up when touched.


*If you use whole wheat flour you will want to add 2 extra TBSP of coconut milk. It absorbs more liquid then white.
**I blend my oats to give them a fluffier texture. I make my own oat flour by putting 1 cup of rolled oats/quick cooking oats, into a high powered bender for 30 seconds or until fairly smooth.

Banana oat muffins with oat flour

Yes you can make banana oat muffins with oat flour. All you need to do is substitute the prescribed amount of rolled oats with oat flour. Then use one tablespoon less of the oat flour since it is more compact than the oats. Or if a recipe calls for only wheat flour you could make the same recipe with half wheat flour and half oat flour. If you alter the recipe by substituting half of the wheat flour for oat flour, make sure to add about 1-2 tablespoons of extra liquid (milk) to the recipe. Did you know that you can make your own oat flour?

How to Make Oat Flour

I like to make my own oat flour to add to recipes. And guess what! Making your own oat flour is at least 20 times easier than making pie! All you need is a high powered blender (one that does a fairly good job blending ice) and some oatmeal. Once you have your blender, add the desired amount of rolled oats. Then blend for 30 seconds or until it looks to be a grainy flour texture.

In a larger sized blender, It’s easier to blend a whole cup of rolled oats together than in smaller increments. I have a ninja magic bullet that blends ¼ cup fairly well for me. But if you have a larger blender you will want to try and blend more oats at one time. 

I don’t recommend storing your homemade oat flour for too long, because it goes rancid pretty quickly. If you blend extra oats, store it in an airtight container. I prefer glass because it keeps it fresh longer. It lasts for up to 2 weeks. However, if it’s been longer than that, make sure you smell it to see if it smells rancid. If it doesn’t, it should be safe to use. Storing it in the fridge will help it to last longer.

If you have extra oat flour that you want to use up you should try this gluten and dairy free apple crisp. Or these dairy free blueberry muffins made with some oat flour and chia seeds.

Can I make Banana muffins without sugar?

Yes you certainly can make banana oat muffins without sugar. These banana oat muffins can be made with honey or maple syrup as a substitute for the sugar. Most banana recipes that call for sugar can be made with honey, maple syrup or homemade date puree as a substitute. If you use maple syrup I would cut down the amount of milk you use by a tablespoon.

Homemade Date Sugar Substitute

Another option I use to make these muffins completely sugar free, is to add ⅓ cup of chopped dates that have been softened by cooking them in a ¼ cup of coconut milk. Let them simmer for about 5-7 minutes. After cooking and they have softened, mash them well with a potato masher or a fork. 

How to Store Banana Muffins

Banana oat muffins can be stored on the counter for up to 3 days, on the counter in an airtight container or ziplock bag. Or if I want them them to last longer I store them in the fridge for up to 5 days to keep them tasting fresh. To warm them up place them in the microwave for 15-30 seconds before eating.

Can I freeze Banana Oat Muffins?

Yes you can freeze banana oat muffins. Make sure they are in an airtight freezer container or freezer bag. Just reheat them in the microwave for 30-60 seconds or let them sit out on the counter for 15-20 minutes. And you can also reheat them in the oven by turning the oven on to 300 and heating them for 8-10 minutes. They last for up to 2 months. Still, if I freeze them, I generally try to use them up before a month goes by to make sure they are fresh.
