These Blueberry Muffin Overnight Oats come together in five minutes so breakfast will be ready right when you wake up! This easy overnight oat recipe tastes like blueberry muffins and can be served cool or warm.

The past few days have been unseasonably hot here in Seattle, with the temperature cracking the 80s earlier in the week, and it’s luckily stayed in the realm of sundress weather. Being able to photograph on my patio without the need for two jackets and a scarf has been a blessing. My body is also thankful for the extra dose of vitamin D it’s getting from my long daily walks to soak up the sun.
Seattle transforms during the spring and summer, turning from the land of rain and gloom into a sunshine-y, blue skied place with lots of glimmering water and pale locals trying to catch a tan while the sun hangs around ever so briefly. I don’t think summer is here quite yet, as the forecast is predicting a weekend full of rain, but the teases of summer have definitely infected the atmosphere up here.

With the sunshine comes a change in diet, too. Say buh-bye to the heavy hearty dishes and give a big wave hello to fresh produce, lighter dishes, and cold refreshing treats. One of my winter to summer changes starts with breakfast. Well, mainly it starts with oatmeal, going from warm, freshly made oatmeal to easy peasy cold & creamy overnight oats!
While I love the ritual of making oats in the morning (like these chocolate peanut butter ones or this chocolate strawberry oatmeal), I know not everyone has the luxury of working from home like I do and you all don’t have time to fuss over oatmeal making in the morning. So, I bring you overnight oats: oatmeal made cold, creamy, refreshing, and totally delicious.

If you haven’t had or heard of overnight oats (where’s the rock you’ve been living under?), they’re made like this: instead of simmering oats with water or milk, you whisk rolled oats with liquid and flavorings of choice, place in a jar or bowl, and let the sit in the fridge overnight where the liquid will absorb into the oats and everything will get creamy and delicious.
The flavor options are pretty much endless. But, I made a classic recipe that I absolutely adore: blueberry muffin overnight oats! They’re so simple. It’s magical what a dash of cinnamon and scoop of dried blueberries will do for a bowl of oatmeal. I also added a splash of vanilla extract to add some warmth!

Also, make sure sure that you use rolled oats and not quick oats. If you use quick-cooking oats, you’ll have a big bowl of mush in the morning. A delicious bowl of mush, but mush nonetheless, and that’s not what we’re going for here.
These overnight oats come together in less than five minutes. You can grab a jar on your way to work for the quickest breakfast ever. If you’re not into cold oats, pop them in the microwave for 30 seconds to warm them up first, but I like ’em cold, especially on hot days! You can also add some topping if you’d like (and I always like!). I opted to top these simply with fresh blueberries and some chopped almonds. A drizzle of almond butter would be delish too ;)

This gluten-free breakfast is a lifesaver on busy days. Between the cinnamon and the dried blueberries that plump up overnight, you’ll get the blueberry muffin vibes you want for breakfast, but way better for you. Whip up a batch, and enjoy!

I never had overnight oats but I will definitely try your recipe! Nothing better than breakfast ready in the morning, especially on a Monday morning :) Looks so great!
Right?! I’m totally about to go grab one of these out of the fridge for breakfast :) thanks, Oana!
I gotta try this. Anything with blueberries is tasty to me, thanks for the idea
Yes to the return of fresh berry season! I know you can get berries year-round, but there’s something about the crazy cheap berries in the summer…I end up buying wayyy too many. Haha! I love the idea of topping overnight oats with blueberries. Clearly I need to stock up on blueberries since they are on sale again this week! :-)
Absolutely love the flavor combination happening here, and I’m ALL about quick prep and then a meal, so I’m totally making these next week. Also, here in Wisconsin it has been crazy warm too – isn’t it nice being able to photograph and not freeze?
I love overnight oats and blueberry muffins, so this is THE perfect breakfast for me! These look great, Rachel!
I think you’ve made me decide to finally make some overnight oats! I have everything for this in the kitchen, and it would be a great way to wake up! These look delish!
These sound and look delicious! I love that you can eat them cool or warm, and that you’ve used Greek yogurt. Great way to add some protein! Pinning your recipe to try. :)

Hi Karen, I just updated the post to include nutritional info. Enjoy!
I can’t find dried blueberries at my grocery store. Can I use fresh blueberries instead?
Yes you certainlu can!!
Question. Yogurt for whatever reason doesn’t agree with me. Any idea of what to use instead?
Dairy-free yogurt would be a great alternative! Otherwise, extra milk should work.
