how are these Banana Blackberry Oatmeal Muffins healthy?

These Banana Blackberry Oatmeal Muffins aren’t just delicious; they’re also packed with health benefits:

  1. Nutrient-Rich Ingredients: The main ingredients of these muffins, including oats, bananas, and blackberries, are all nutrient-rich. Oats are a great source of fiber and essential nutrients like manganese, phosphorus, and magnesium. Bananas are loaded with potassium, vitamin C, and vitamin B6, while blackberries are rich in antioxidants and vitamins.
  2. Naturally Sweetened: These muffins are naturally sweetened with ripe bananas, eliminating the need for added sugars. This makes them a healthier option compared to traditional muffin recipes that often contain refined sugars.
  3. Low in Added Fats: Unlike many store-bought muffins that are loaded with added fats like butter or oil, these muffins use ripe bananas as a natural binding agent, reducing the need for excessive amounts of added fats. (Disclaimer: I have nothing against fats – I love them – but this is just an added bonus).
  4. High in Fiber: With the inclusion of oats and blackberries, these muffins are high in dietary fiber. Fiber is essential for digestive health, helps regulate blood sugar levels, and promotes feelings of fullness, making these muffins a satisfying and nutritious option for breakfast or snacks.

Overall, these Banana Blackberry Oatmeal Muffins are a delicious and nutritious option for anyone looking for a wholesome snack or breakfast choice. They’re easy to make, require minimal ingredients, and offer a host of health benefits that make them a standout recipe in any kitchen.

Ingredients and Substitutions:

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

Banana Blackberry Oatmeal Muffins Ingredients.

Oats: Rich in fiber and essential nutrients, oats provide a hearty muffin base. Blending them creates a smoother texture in the batter, ensuring a delightful consistency in the final product. You will need to blend the oats into a fine flour-like consistency. You can also use store-bought oat flour.

Ripe Bananas: Ripe bananas are the natural sweetener and binding agent in these muffins. Their ripe, naturally sweetened flavor adds a delicious taste and moistens the batter, eliminating the need for excessive amounts of oil or butter. Packed with potassium and other essential nutrients, ripe bananas contribute to the overall healthiness of these treats.

Baking Powder: Baking powder acts as the leavening agent in this recipe, working its magic with almond flour to make the muffins light and fluffy. It helps the batter rise, resulting in a soft and airy texture.

Water: A minimal amount of water is added to the recipe to balance the moisture content and help create the desired consistency in the batter. This simple addition ensures that the muffins remain soft without becoming overly dense. You can add your choice of milk to add a bit of extra protein to your banana oatmeal muffins.

Blackberries: You can use fresh or frozen blackberries; I prefer fresh for this recipe as they contain less moisture than frozen blackberries.

Optional Flavor Boosters: If you happen to have salt and vanilla extract in your cupboard, go ahead and add these in. They will boost the flavors deliciously. However, it is definitely not essential. I also like to add a sprinkle of coconut sugar for an extra touch of sweetness and whole oats for visual appeal.

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 Banana Blackberry Oatmeal Muffins:

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

Step 1:
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 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 2:
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 3:
Add blended oats and baking powder to a bowl and give it a mix to ensure the baking powder is evenly distributed. If you’re adding salt, you can also add this now.

Step 4:
Mash your bananas with a fork until you can’t mash no more. Try to mash it until it’s very well-mashed; otherwise, your batter may be too dry.

Step 5:
Add the mashed banana and water to the dry ingredients. If you’re using vanilla extract, add this now too.

Step 6:
Fold with a spatula to combine.

Step 7:
Fold in your blackberries.

Step 8:
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 coconut sugar and whole oats on top as a decoration.

Step 9:
Bake your muffins for 22-30 minutes (22 minutes for smaller muffins and 30 minutes for larger muffins). Remember that some ovens are hotter than others, so keep an eye on them and play around with the baking times to reach your desired texture. You can test for doneness by inserting a skewer in the middle – it should come out with just a few moist crumbs – if there’s still muffin batter on the skewer, pop them back in the oven for a couple of minutes. They should be slightly underdone and gooey in the middle. If you bake them too long, they will be dry. Leave to cool in the tin for 10 minutes then carefully remove and enjoy.

Tips and Notes

Use Ripe Bananas: Ensure your bananas are ripe for the best flavor and sweetness. Ripe bananas are easier to mash and provide natural sweetness to the muffins. Look for bananas with brown spots on the peel.

Customize Your Muffins: Feel free to customize these muffins to suit your preferences. You can add optional ingredients like vanilla extract, salt, or coconut sugar for extra flavor. Additionally, you can swap blackberries for other fruits like blueberries, raspberries, or chopped nuts.

Properly Blend Oats: When making your own oat flour, blend the oats into a fine powder-like consistency. This ensures a smoother texture in the batter and prevents any graininess in the muffins. If using store-bought oat flour, ensure it’s finely ground for best results.

Don’t Overmix the Batter: When combining the wet and dry ingredients, be careful not to overmix the batter. Overmixing can result in dense and tough muffins. Fold the ingredients together gently until just combined for light and fluffy muffins.

Adjust Baking Time: Baking times may vary depending on your oven and the size of your muffins. Keep an eye on them towards the end of the baking time and adjust as needed. Muffins are done when a toothpick inserted into the center comes out with just a few moist crumbs attached.

Cool Before Removing: Allow the muffins to cool in the tin for at least 10 minutes before removing them. This allows them to set and makes them easier to remove without sticking. Use a butter knife or offset spatula to gently loosen the edges if needed.

Enjoy Fresh or Reheat: These muffins are delicious served fresh from the oven or reheated. Simply microwave for a few seconds until warmed through, or enjoy at room temperature. They make a perfect grab-and-go breakfast or snack option for busy days.

By following these tips and notes, you’ll be able to make perfect Banana Blackberry Oatmeal Muffins every time, customized to your liking and enjoyed by all!

How to store Banana Blackberry Muffins

Room Temperature: Store leftover Banana Blackberry Oatmeal Muffins in an airtight container at room temperature for up to 3 days. Ensure the container is tightly sealed to maintain freshness and prevent them from drying out.

Refrigeration: For longer storage, you can refrigerate the muffins. Place them in an airtight container or resealable plastic bag and store them in the refrigerator for up to a week. Refrigeration helps extend the shelf life of the muffins while keeping them moist and fresh.

Freezing: If you want to store the muffins for an extended period, freezing is the best option. Wrap each muffin individually in plastic wrap or aluminum foil to prevent freezer burn and maintain freshness. Alternatively, you can place the muffins in a single layer in a freezer-safe bag or container. You can freeze these muffins for up to 3 months.

Thawing: When you’re ready to enjoy the frozen muffins, thaw them overnight in the refrigerator. Alternatively, you can microwave them for a few seconds until warmed through. Avoid thawing the muffins at room temperature, as this can lead to uneven thawing and potential moisture loss.

Reheating: Reheat the thawed or refrigerated muffins before serving, if desired. Microwave them for a few seconds until warmed through, or place them in a preheated oven at 300°F (150°C) for about 5-10 minutes. Enjoy the muffins warm for the best taste and texture.

By following these storage instructions, you can enjoy freshly baked Banana Blackberry Oatmeal Muffins for days to come, whether at room temperature, chilled in the refrigerator, or conveniently stored in the freezer for future use.

Can I use frozen blackberries instead of fresh ones?

Yes, you can use frozen blackberries in this recipe. However, keep in mind that frozen blackberries may release more moisture during baking, which could slightly affect the texture of the muffins. If using frozen blackberries, you don’t have to thaw them first.

Can I substitute oats with oat flour?

Yes, you can substitute oats with oat flour in this recipe. If using oat flour, you can skip the step of blending oats into a fine powder-like consistency. Use an equal amount of oat flour as the recipe calls for oats.

How can I make these muffins gluten-free?

To make these muffins gluten-free, ensure you use certified gluten-free oats and baking powder. These ingredients are naturally gluten-free but can sometimes be processed in facilities that also process gluten-containing grains. Using certified gluten-free ingredients will ensure the muffins are safe for those with gluten intolerance or celiac disease.

Can I add nuts or seeds to the muffins for extra crunch?

Yes, you can add chopped nuts, such as walnuts or pecans, or seeds, such as pumpkin or sunflower seeds, to the muffins for extra crunch and texture. Simply fold them into the batter along with the blackberries before baking.

Are these muffins suitable for meal prepping?

Yes, these muffins are perfect for meal prepping. You can bake a batch at the beginning of the week and store them in an airtight container for quick and convenient breakfasts or snacks throughout the week. Follow the storage instructions provided to ensure the muffins stay fresh and delicious.

Can I omit the blackberries or use a different fruit?

Yes, you can omit the blackberries or substitute them with another fruit of your choice, such as blueberries, raspberries, or diced strawberries. Feel free to customize the muffins to suit your taste preferences or what you have on hand.

Are these muffins suitable for vegan diets?

Yes, these Banana Blackberry Oatmeal Muffins are vegan-friendly as they contain no animal products. They’re made with plant-based ingredients and are perfect for those following a vegan diet or looking for dairy-free options.
