Blueberry Banana Overnight Oats

Juicy blueberries and ripe sweet bananas are the stars in this delicious wholesome overnight oats recipe!

Blueberry Banana Overnight Oats Recipe

This delicious recipe marks the end of blueberry season for me. Well kinda… I still have a couple big bags of blueberries in my freezer but as for blog recipes this is it. Over the last couple months I made a slow cooker blueberry banana steel cut oatmeal recipe, a blueberry banana baked oatmeal cup recipe, and a blueberry banana greek yogurt muffin. I also used countless blueberries in smoothies and plan to make many more smoothies with the blueberries I have left. It has been blueberry heaven over here. Banana heaven too I guess considering each recipe has a ripe sweet banana in it.

This is the thing with bananas. I love them. I always have a couple on my counter needing to be used up so more often than not bananas will find their way into my recipes. Especially, breakfast or baked good recipes. Here’s a post on using up ripe bananas.


Blueberries and bananas were meant to be. Truly. The slight tartness of a blueberry goes perfectly with the sweet flavor of a ripe banana. And when you combine those flavors you don’t even need a lot of added sugar because the fruit provides most of the sweetness.

I don’t know why I never thought to make an overnight oats recipe with blueberries and bananas before. It seems like such a natural combination. I should mention that this recipe will most likely be the last of the overnight oats recipes for a while. I tend to eat cold oatmeal more in the summer and now that back to school is right around the corner my mind is starting to go toward breakfast burrito recipes. Don’t fret though because I’m leaving you with 3 amazing overnight oat recipes. Last week I shared an almond joy inspired recipe that is killer. Today I’m sharing this blueberry and banana one. And in a couple days look for a new overnight oats recipe with juicy strawberries.


Overnight oats recipes are so simple to put together and can be made 3 – 5 days ahead of time. I don’t make  more than 3 at a time but I’ve had readers tell me their oats are fine at 5 days.

For this recipe I just mixed together rolled oats, chia seeds, and unsweetened coconut milk. Chia seeds add extra protein and fiber to the recipe. They also create a delicious pudding-like texture with the oats. I’ve made overnight oats without them so if you don’t have any or don’t want to use then leave the chia seeds out. For the milk you can use whatever milk you like.


Once I mixed those ingredients together I stirred in a little pure vanilla extract and then added in a 1/2 banana and 1/2 cup of blueberries. You can use fresh or frozen blueberries. Mine were originally fresh but then I put the blueberries in the freezer so I guess you can say I used frozen blueberries in this recipe. Both will work fine.

After you have the ingredients together, put the lid on, and refrigerate overnight. The oats are going to be thick when you take the jar off. Give it a couple stirs and add a little extra milk to loosen up the oats. I also add 1 tablespoon of pure maple syrup at for extra sweetness.

For all of my overnight oats recipes I use a 16-ounce (pint size) mason jar. These work great and are the perfect portion-controlled “on the go” vessel.

Here’s a quick “how to” video to bring this recipe to life for you.

This is a delicious summer breakfast recipe to help you enjoy the end of the season blueberries. It’s filled with wholesome oats and lots of fruit to keep you satisfied until lunch.

  1. This looks so yummy! I really like blueberries and bananas together, too. Do you have to used rolled oats or could you use any type of oat?

    Great Breakfast ideas!! I am trying to take off 20 lbs and I am 54 years old, the older you get the harder it is to take off. Anyhow…I am going to try these great overnight oats recipes and along with better meal choices, drinking more water and riding my bicycle daily this should be accomplished. Any helpful information would be greatly appreciated.

  3. This is on my snack list tonight. Thanks for sharing Tammy 🙂

  4. Most I have used need to be cooked first. What are you doing with the oats? Just putting them in dry? Also what brand do you use?,Awesome Idea.

  5. When do you add in the vanilla? I did not see that in the instructions.

  6. Can you leave out the maple syrup as I don’t have any and can I use Almond milk as that is what I have on hand? Were supposed to get a snow storm tonight into tomorrow and I was gonna fix it for breakfast.
    Thanks in advance. Renee

  7. Are you adding 1 tsp of chia seeds or 1 tbs to get to 8 g of protein?

  8. This sounds so yummy. My husband would love this! Great recipe!

  9. Do the bananas not turn brown and slimy? That’s my only fear…

  10. I didn’t think I would like cold oatmeal, but I have to say this was delicious!!! Surprisingly the bananas did not turn brown. A new breakfast favorite!

    I love your overnight oats recipes i have tried several of them and love each one I have made, I also really like your baked oatmeal as well. The blueberry banana overnight oats is one of my favorite recipes.

    I followed the directions exactly since this is my first time making overnight oats. This morning, after almost 11 hours in the fridge, the oats we’re exactly like they were last night. The coconut milk got solid or thick from getting cold in the fridge. Should I have stirred it? The directions said to do that after it sat all night.


    • Did you the coconut in the can or carton? The coconut milk in the carton should not get solid. If it thickens up I will add a little more milk to loosen it up in the morning and that should do the trick.
