A spoonful of blueberry overnight oats held over a white bowl next to a glass of milk

Blueberry Muffin Overnight Oats

5 from 3 votes
All the blueberry muffin flavor, but much less effort and a healthier alternative 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.
Prep Time 5 minutes
Total Time 8 hours 5 minutes
Servings 1 serving


  • ½ cup old fashioned rolled oats, for gluten free, I recommend Bob’s Red Mill
  • ½ to ⅔ cup plant-based milk, I prefer cashew milk, depending on preferred thickness
  • 1 Tablespoon cashew or almond butter
  • 1 Tablespoon chia seeds
  • 1 to 2 teaspoons pure maple syrup, to taste (or honey if not vegan)
  • ½ teaspoon ground cinnamon
  • ½ teaspoon pure vanilla extract
  • Pinch of sea salt
  • ¼ cup fresh blueberries


  • In a small jar, combine all ingredients except for blueberries, and stir to combine. Gently fold in blueberries. If it would be easier, you can combine everything in a small bowl and then transfer it to a jar.
  • Cover with lid and refrigerate overnight. Serve as is, or warm it up in the microwave. Enjoy!


Portions: I usually make a double batch so that I have two servings ready to go (which is what you see pictured in the post)! But you can always prepare a single serving as outlined above.
