Banana Blueberry Oatmeal Muffins.

Blueberry muffins are the KING of muffins, in my opinion. There’s just something riveting about the pop of sweet blueberries in a mouthful of a moist, fluffy muffin. Add some lemon to the mix and you have a muffin that is really tough to beat. It’s just so good. Plus, using mashed banana adds an extra level of moisture and natural sweetness that truly elevates these muffins to the next level of deliciousness.

I’ve been obsessed with baking with oatmeal recently and I’ve made LOADS of oatmeal muffins including my Blackberry Banana Oatmeal Muffins and Carrot and Banana Oatmeal Muffins, but none have been as good as these. Baking with oats can sometimes end up a tad on the dry side, but not these banana blueberry oatmeal muffins. Even without adding oil or fat, they’re still light, fluffy and perfectly moist.

These banana blueberry oatmeal muffins are a perfect healthy snack to meal-prep for the week and have on-the-go or have two or three (or four – who’s counting?) for breakfast. They’re made with nourishing ingredients that you probably already have in your kitchen!

What makes these Banana and Blueberry Oat Muffins healthy?

These Banana Blueberry Oatmeal Muffins are not only delicious but also packed with nourishing ingredients that offer several health benefits:

1. Bananas: Bananas are high in potassium, which supports heart health and helps regulate blood pressure. They provide natural sweetness, reducing the need for added sugars and they are a good source of dietary fiber, aiding in digestion and helping to maintain a healthy gut.

2. Greek Yogurt: Greek yogurt is an excellent source of protein, which is essential for muscle repair and growth. It also contains probiotics that promote a healthy digestive system and is rich in calcium, which is important for bone health.

3. Oatmeal (Oat Flour): Oats are whole grains, which are important for a balanced diet. They are also high in soluble fiber, and help to lower cholesterol levels keeping you feeling full longer, and they provide sustained energy, making them an ideal choice for breakfast.

4. Blueberries: Blueberries are one of the best sources of antioxidants, which help protect the body against oxidative stress and inflammation. They are also rich in vitamins C and K, which support immune function and bone health.

5. Natural Liquid Sweeteners: Sweeteners like honey, maple syrup, and agave have a lower glycemic index compared to refined sugar, which helps to avoid blood sugar spikes. These sweeteners also contain trace amounts of minerals and antioxidants.

These muffins are not just a treat for your taste buds but also a wholesome and balanced snack or breakfast option, ensuring you start your day with a nutritious boost.

Banana Blueberry Oatmeal Muffins Ingredients

These are the ingredients you’ll need to make these Blueberry Banana Muffins. You can find the exact measurements in the recipe card at the bottom of this page.

You will only need seven ingredients to make these muffins – you probably have most of them (if not all) in your kitchen just waiting to be turned into banana blueberry oatmeal muffins!

  • Ripe Bananas: One of the best healthy baking ingredients! They not only add flavour and sweetness to your muffins, but using mashed banana also mimics eggs by providing the muffins with a strong structure. They’re also used to replace oil in some recipes due to their moistness. Make sure you are using ripe bananas(borderline black – see my bananas below!).
  • Yoghurt: I use Greek yoghurt in my muffins as it contains a great amount of protein, which helps build and maintain muscle and also makes these muffins more satiating! This also adds to the muffins’ moistness without needing to use butter or oil.
  • Liquid Sweetener: To add sweetness while keeping this chocolate orange cake refined sugar-free, I recommend using a natural liquid sweetener like honey, maple syrup, agave, or date syrup.
  • Lemon: This adds a lovely citrusy flavour that goes so well with blueberries! It also helps with the leavening as it reacts with the baking soda making your banana blueberry muffins nice as fluffy!
  • Oatmeal: Technically you will need oat flour, but that is simply just blended uncooked oatmeal! You can also buy oat flour or even use homemade oat flour, but I find it more affordable to buy a big bag of oats, blend it and store it in my baking cupboard.
  • Baking Soda: Also known as Bicarbonate of Soda, this is what makes the banana blueberry muffins rise!
  • Blueberries: You can use fresh or frozen blueberries. Make sure to use ripe, juicy blueberries since it enhances the taste and texture of the banana blueberry oatmeal muffins.

Liquid Sweetener – You can use maple syrup, agave, honey, coconut nectar or any similar syrup. I don’t recommend brown sugar since brown sugar is dry and granulated, meaning you have to adjust the recipe due to the change in moisture and texture.

Lemon – if you don’t have any lemons, you can use vinegar or apple cider vinegar instead – since apple cider vinegar is acidic and can help activate the baking soda in the recipe, similar to what lemon juice does.

Yogurt – you can use any type of yogurt, Greek yogurt, soy yogurt, almond yoghurt or even coconut yogurt to make these blueberry banana muffins vegan!

Oatmeal – these are banana blueberry oatmeal muffins, so if you’re looking for a blueberry banana muffin recipe with an alternative flour you can try these Banana Buckwheat Muffins.

Baking Soda – I do not recommend replacing this with Baking Powder as the texture and flavour will be altered. If you don’t have baking soda and want to make these blueberry muffins, you can try using double the baking powder. I have not tested this myself yet, but if you do, let me know in the comments!

equipment needed:

  • Digital Food Scale: To accurately measure your ingredients.
  • Blender: You will need a blender or food processor to blend the oats into a fine flour-like consistency OR you can use oat flour.
  • Silicone Muffin Tray: These carrot banana muffins are fat-free, which causes them to stick to a regular muffin tray and paper liners. Therefore, I suggest a silicone muffin tray or a non-stick tray for easy removal!
  • Mixing Bowl: To combine all your healthy carrot muffin ingredients.
  • Plate: This makes mashing your bananas a lot easier!

How to make Blueberry Banana Oatmeal Muffins

Here is a detailed summary of how to make these banana blueberry oat muffins. I’ve also included some photos, and you can watch the recipe video in the recipe card

These banana blueberry oat muffins truly are incredibly quick and easy to make! You can make them in just one large bowl if you’re like me and don’t like washing up!

Step one:
Start by preheating your oven so that it’s hot and ready for your muffin batter. Grab your muffin tray and lightly grease it with some cooking spray or butter or insert paper liners. I like to make my muffins without muffin cases, as they tend to stick to the paper because of the lack of fats in the muffins. Sometimes I like to make my own paper liners by cutting squares of parchment paper and then pressing them into the muffin cavities. I make six large muffins, but you can make eight smaller muffins if you prefer.

Step two:
If you’re making your own oat flour: add whole oats to a blender and blend into a find powder. You can use the ground oats as is or take it a step further and sift it for a finer, softer texture.

How to make oat flour: blend and sift whole oats.

Step three:
Mash your bananas. The riper they are, the easier they will be to mash. You can use a fork, potato masher or even pop them in a blender! The use of mashed banana plays a crucial role in the texture, flavor, and structure of these banana blueberry oatmeal muffins.

Step four:
Add the mashed banana, yogurt, liquid sweetener, lemon juice and lemon zest to a mixing bowl and whisk until well combined.

Step four:
Add in your blended oats, baking soda and a pinch of salt and fold until combined.

Step five:
Gently fold in your blueberries to your muffin batter. This ensures that they’re evenly distributed and every bite is packed with vibrant blueberry flavor. If you’re using frozen blueberries try not to fold them too much – otherwise, you will end up with purple banana blueberry muffins (thinking about it now, that actually sounds quite cool!)

Step six:
Evenly distribute the batter between 6 muffin cavities for large muffins or 8 muffin cavities for smaller muffins. Fill them as much as you can; it might feel like there’s too much batter, but the muffins won’t grow that much in the oven. You can add some whole oats or sugar on top as a decoration.

Tips and Notes for the best Banana Blueberry Oatmeal Muffins

  • Use Very Ripe Bananas: For the best flavor and sweetness, make sure your bananas are very ripe, ideally with black spots. This will also help achieve the right moisture level in your muffins.
  • Homemade Oat Flour: If you’re making your own oat flour, ensure that you blend the oats into a fine powder. Sifting the blended oats can give you an even finer texture, resulting in a lighter muffin.
  • Yogurt Options: You can use any type of yogurt for this recipe. If you prefer a dairy-free option, soy, almond, or coconut yogurt works well. Greek yogurt adds extra protein and moisture.
  • Sweeteners: Adjust the amount of liquid sweetener to suit your taste. Honey, maple syrup, agave, or date syrup are all excellent choices. Avoid using granulated sugar as it alters the moisture content and texture of the muffins.
  • Lemon Alternatives: If you don’t have lemons, apple cider vinegar or white vinegar can be used for the acidity needed to activate the baking soda. This ensures the muffins rise properly.

  • Blueberries: Both fresh and frozen blueberries work well. If using frozen blueberries, try not to overmix the batter to prevent the color from bleeding too much. This can help maintain the vibrant look of the muffins.
  • Muffin Liners: These muffins are low in fat, so they may stick to paper liners. Using a silicone muffin tray or lightly greasing the muffin cavities can prevent sticking. Alternatively, you can cut squares of parchment paper and use them as liners.
  • Baking Time: Keep an eye on your muffins as baking times can vary depending on your oven. Start checking for doneness at around 18 minutes. A toothpick inserted into the center should come out almost clean. I like to slightly underbake mine so that they don’t turn out dry.
  • Add-ins: Feel free to add nuts, seeds, or additional spices like cinnamon or nutmeg to customize your muffins. These can add extra nutrients and flavor.

By following these tips and notes, you can ensure your Banana Blueberry Oatmeal Muffins turn out perfect every time. Enjoy baking and indulging in these healthy, delicious treats!

How to store Banana and Blueberry Oat Muffins

To ensure your Banana Blueberry Oatmeal Muffins stay fresh and delicious, follow these storage tips:

Room Temperature: Store the muffins in an airtight container at room temperature for up to 2 days. This keeps them moist and ready to eat without needing to reheat.

Refrigeration: For longer storage, place the muffins in an airtight container and refrigerate for up to a week. This method helps maintain their freshness and prevents spoilage.

Freezing: If you want to keep the muffins for an extended period, they can be frozen. Arrange the muffins in a single layer on a baking sheet and freeze until solid. Once frozen, transfer the muffins to a resealable plastic bag or an airtight container. They can be stored in the freezer for up to 3 months. To enjoy, thaw the muffins at room temperature or reheat them in the microwave or oven.

Reheating: To reheat refrigerated or frozen muffins, place them in the microwave for 20-30 seconds or warm them in a preheated oven at 350°F (175°C) for about 10 minutes. This will restore their softness and enhance the flavors.

By following these storage instructions, you can enjoy your Banana Blueberry Oatmeal Muffins anytime, whether you need a quick breakfast, a healthy snack, or a satisfying treat.

Can I use regular flour instead of oat flour?

Yes, you can substitute regular flour for oat flour if you don’t need the muffins to be gluten-free. However, the texture and nutritional profile will change. You may need to adjust the amount slightly, as regular flour is denser than oat flour.

Can I make these muffins vegan?

Absolutely! To make these muffins vegan, use a plant-based yogurt such as soy, almond, or coconut yogurt. Also, choose a vegan liquid sweetener like maple syrup or agave.

What if I don’t have Greek yogurt?

You can use any type of yogurt you have on hand. Regular yogurt, whether it’s dairy or plant-based, will work well in this recipe. Just note that Greek yogurt is thicker and adds more protein.

Can I add other fruits or nuts?

Yes, you can customize your muffins by adding other fruits like raspberries, strawberries, or chopped apples. Nuts like walnuts, almonds, or pecans also make great additions. Just be sure to adjust the amount to avoid overfilling the muffin batter.

Can I use a different sweetener?

Yes, you can use various natural liquid sweeteners such as honey, maple syrup, agave, or date syrup. Avoid using granulated sugars without adjusting the recipe, as they can change the moisture content and texture of the muffins.

How do I prevent my muffins from sticking to the liners?

Since these muffins are low in fat, they can stick to paper liners. To prevent this, use a silicone muffin tray, lightly grease your muffin cavities, or use parchment paper squares as liners.

Can I use frozen blueberries?

Yes, you can use frozen blueberries. To prevent the batter from turning purple, try not to overmix once the blueberries are added. Adding them while still frozen can also help minimize color bleeding.

How do I know when the muffins are done baking?

The muffins are done when a toothpick inserted into the center comes out clean. This usually takes about 18-22 minutes, but baking times can vary depending on your oven. Start checking at around 18 minutes to avoid overbaking.
