These blueberry muffin overnight oats taste like a blueberry muffin thanks to cinnamon, vanilla and fresh lemon zest. Prepare this simple recipe the night before to wake up to a wholesome, filling breakfast that’s ready to eat straight from the fridge.

Ingredients

Here’s what you’ll need to make these overnight oats:

  • Fresh blueberries. I used a whole cup of fresh blueberries in the recipe. I really like this recipe with fresh blueberries but in a pinch, you can use frozen.
  • Rolled oats. Rolled, or old-fashioned oats have the best texture for overnight oats. Large flake oats also work well.
  • Ground flax. Ground flax helps to thicken the recipe and also adds some essential fatty acids. I like ground flax best in this recipe as it lends to the muffin flavour but you can also use chia seeds in a pinch.
  • Lemon zest. Lemon zest is key for the blueberry muffin flavour! To make fresh lemon zest, grate the skin of a lemon until you have about 1 heaping tsp worth. This is optional but highly recommended!
  • Muffin flavour enhancers. To lend to the blueberry muffin flavour of these oats, you’ll need vanilla extract, cinnamon and sea salt. These are all optional but recommend to enhance the flavour.

Yogurt Option

A lot of blueberry muffin overnight oats recipes call for yogurt but it’s not something I always have on hand so I decided to leave it out of the recipe. That being said, yogurt does make it extra thick and creamy and adds a wonderful flavour, especially if you use vanilla yogurt.

If you want to try the recipe with a plant-based yogurt such as coconut, almond or cashew, use 1/3 cup plant-based milk and 1/3 cup yogurt instead of 2/3 cup milk.

Blueberry Overnight Oats Recipe

This delicious overnight oatmeal couldn’t be easier to make. Simply add everything to a container, mix well and stash in the fridge. In the morning, they’ll ready to eat!

Recipe Notes

This recipe serves one and I’d recommend making it as one portion per container but you can easily prepare 2 or more servings at once. The prepared recipe will keep in the fridge for up to 3 days but it’s best within 1-2 days since it’s made with fresh blueberries.

Topping Ideas

I enjoy these as is. They’re already quite filling and delicious without any toppings but if you want to add something extra to them, I recommend:

Notes

To make these blueberry protein overnight oats, omit the maple syrup, add 1 scoop vegan vanilla protein powder and increase the liquid to 3/4 cup. You may need slightly more liquid based on the protein powder you use. 

Use 2/3 cup liquid for porridge-consistency overnight oats, if you like your overnight oats thick and doughy, reduce the liquid to 1/2 cup.

For creamier oats, use 1/3 cup dairy-free yogurt and 1/3 cup plant-based milk instead of 2/3 cup plant-based milk.
