Blueberry muffin overnight oats have all the blueberry muffin flavor, but much less effort for breakfast! Only 5 minutes of prep before you let the fridge do the rest of the work overnight, and the next morning it can be served cold or warm.
In a small jar, combine all ingredients except for blueberries, and stir to combine. If it's easier, you can combine everything in a small bowl and then transfer it to a jar.
Gently fold in blueberries. Cover with lid and refrigerate overnight.
Serve as is, or warm it up in the microwave. Enjoy!
