Can we all agree that Blueberries and Oats are a perfect match? Seriously, you can always catch me adding blueberries to my baked oatmeal, breakfast oats or any other oaty recipe.

This recipe for Healthy Blueberry Oatmeal Muffins is a seriously perfect combo. The combination of rolled oats, whole-grain flour and coconut sugar for muffins that are filled with fibre and have an incredible flavour and texture!

These muffins are also dairy-free and can easily be made gluten-free using a 1-1 gluten-free flour blend. I do my best to make most of my recipes dairy-free and gluten-free, especially when baking. See my Lemon Poppyseed Muffins and Chocolate Chip Zucchini Bread recipes for proof!

Is it better to use fresh or frozen blueberries for muffins?

Fresh blueberries are best, but both will work for this recipe.

Since fresh blueberries tend to have a stronger flavour more *blueberry* flavour, they will give you a better tasting muffin with more of that rich blueberry taste. But, if blueberries aren’t in season – go for frozen!

If using frozen blueberries, make sure to add them into the muffins frozen, no need to defrost them! If you do, the blueberries will be too watery and won’t hold together well in the muffins.

How to make healthy blueberry oatmeal muffins

Mix the dry ingredients together in a bowl, then add the blueberries and toss in the dry mixture. Then Mix the wet ingredients together in a bowl, then add the wet ingredients to the dry ingredients and mix until combined.

Spoon the batter into your muffin pan lined with muffin liners so each mould is 3/4 of the way full and bake at 400 degrees F for 18-20 minutes.

Let the muffins cool for at least 30 minutes before diving in. This will give them a chance to firm back up and will make it easier to remove the muffin liner.

Flour substitutions

Here are some types of flours you can equally substitute in this recipe for spelt flour:

Don’t substitute all almond flour or coconut flour in this recipe. If you want to add these flours, you can replace up to 1/4 of the amount of total flour. (i.e. You can replace 1/3 cup of spelt flour in the recipe with 1/3 cup of almond flour.)

Expert tips

  • Use blueberries that are slightly firm. If your blueberries are mushy, they will fall apart in the batter and you’ll end up with blue muffins.
  • Make sure to toss the blueberries in with the dry ingredients before adding the wet ingredients! This will coat the blueberries in the flour mixture, and it will help prevent the blueberries from sinking to the bottom.
  • If using frozen blueberries, don’t defrost them. Add them right in frozen!
  • Rolled oats will give these muffins a delicious texture. You can use quick oats too, but you won’t get the same chewy and rich texture.

Storage tips

How to store: Store these muffins in an air-tight container or bag on the countertop for up to 2 days. After that, transfer to the fridge to keep them fresh. These muffins will stay fresh in the fridge for up to 6 days.

How to freeze: Let the muffins cool completely, then transfer to a freezer bag and place in the freezer for up to 2 months. Thaw at room temperature.
