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:
- chopped walnuts or pecans
- coconut yogurt
- almond butter
- chia seed jam

I’m wondering if this would work with frozen blueberries as that’s what I have on hand?
Yep, thatโs ok. Iโd just use a bit less since theyโll thaw and add extra moisture. Or you thaw separately in the fridge overnight and mix them in in the morning.
Very good! The lemon zest really brightens the flavour.
Glad you liked them, Kelly!
Can I use steel-cut oats for this?
Steel-cut oats don’t work very well for overnight oats. You can use them if you don’t mind them being a bit hard and chewy in the morning. I would recommend rolled oats though!
Love this recipe! Simple & easy. Yummy even without the lemon zest. I used some Greek Plain Yogurt & some Ripple Dairy Free milk. Delicious & I find it holds me longer than plain oatmeal mmm ๐ย
Sounds so yummy! Glad you enjoyed it and thanks so much for leaving a review.
