Overnight oats are a great breakfast option for when you simply don’t have a lot of time. Mornings are so crazy now-a-days and far too many of us are skipping breakfast for no reason other than we are simply too rushed. You can make a serving or two of overnight oats at night, and have a delicious breakfast ready for you in the morning. These oats are so versatile and can even be taken on-the-go!
My Peanut Butter and Banana Overnight Oats recipe is one of the most popular recipes on this blog. It’s incredibly delicious! However, if you prefer a lighter oatmeal, or just love the flavor blueberries, then these Blueberry Overnight Oats are definitely worth trying.
This recipe uses unsweetened vanilla almond milk to add a hint of vanilla in each bite, however, you can use any milk that you prefer. I also add a touch of cinnamon for some warm spiciness, flax seeds, and maple syrup (or agave). You can easily adjust all of the flavors to your own personal preferences.
Why This Recipe Works
It’s a super easy, make-ahead breakfast recipe. You can make jars or bowls of this oatmeal for the week and have breakfast practically ready for you as soon as you wake up. It definitely helps during busy weekday mornings.
The combination of flavors is so good together and it is delicious right out of the fridge or can be warmed up on the stove top or in the microwave.
This is a great breakfast option for both kids and adults alike. Oatmeal provides plenty of whole grains, protein and fiber as well as all of the nutrients and antioxidants that blueberries are packed with.
How To Make Blueberry Overnight Oats
Ingredients
- 1/2 cup old fashioned rolled oats: quick oats or steel-cut oats can also be used. See the Tips and Techniques section below for more information.
- 1 teaspoon flax seeds (or chia seeds): can be omitted, if preferred.
- 1/4 teaspoon ground cinnamon
- 1/2 cup unsweetened vanilla almond milk (or any milk that you prefer)
- 1 teaspoon maple syrup (or to taste): you can use agave for a vegan option.
- 1/4 cup blueberries: fresh or frozen can be used.
The entire recipe and instructions can also be found in the recipe card at the bottom of this post. You can also print the recipe from the card, if needed.
Prep!
Rinse the blueberries and gently pat them dry.
Create!
In a bowl or mason jar combine the rolled oats, flax seeds, and cinnamon. Mix well.
Pour in the milk and the maple syrup. Stir until well combined.
Gently mix in the blueberries. Cover and refrigerate at least 6 hours.
Present!
Give the oats a gently stir before serving.
These overnight oats can be topped with extra blueberries and maple syrup immediately before serving, if desired.
Tips and Techniques
- If you forget to make your oats the night before, you can replace the rolled oats with quick oats. Let the oatmeal sit for about an hour and it’s good to go. The texture will be slightly different, but the flavor will be just as good.
- If using steel-cut oats, also known as Irish oatmeal, you may want to let the oats soak for a couple extra hours. Steel-cut oats will be chewier.
- Increase the ratio of milk to oats for a thinner oatmeal. You can use up to 1 cup of milk.
- Overnight oats can be stored, tightly covered, in the refrigerator for up to 5 days. They are a great option for weekly meal prep.

This recipe is SUPER easy! I can put everything in a jar in less than 10 minutes and have a tasty, to-go breakfast ready the next morning. I substitute chia seeds for the flax, and often use frozen blueberries … but the results are still delicious!

Tiffany says
This was an amazing breakfast to make when I had extra blueberries but didn’t want to cook! Threw it together and it was ready and delicious in the am! Thanks
Nancy says
I love this. I used a vanilla high protein yogurt and skipped the other sweetener, my oats tasted like blueberry cheesecake! Also, I found the ratios were spot on for the experience I was looking for.
Thank you very much.
Christie says
This is great! I used frozen blueberries and it was fine! I used a 1/2 cup oat milk but you can use a little less if you want it thicker. I used monk fruit sweetener instead of maple syrup.
Pam says
If you use frozen fruit, it doesn’t turn to mush by morning does it? – Or do you add the fruit and stir just before serving? Thanks
Lauren Vavala says
Hi Pam! I haven’t made these with frozen fruit so I can’t say for sure. It doesn’t change anything to mix in the day of, except the fact the berries would be very cold if you’re not warming up the oats. Or you could give it a try adding them the night before in a small portion the first time and see how the berries hold up. Hope this helps a little.
