Overnight Protein Oats with Blueberry Milk

I have held off for YEARS on making overnight oats. I didn't get it, oatmeal just doesn't take that much time or effort to cook and why would I ever want to eat oats cold anyway? I came across a recipe recently that included nut milk blended with frozen blueberries and since they are in my top 3 fave fruits, I finally bit and made my own version just to see if overnight oats are worth all the hype. Now I'm in regret mode for all the years I could have been enjoying this tasty treat. I also found it's a great snack too, I put mine in a Ball jar and just eat a few spoonfuls out of the fridge when I need a quick bite between meals.


  • ¾ cup frozen blueberries (my favorites are the organic ones from Costco)
  • Juice of ½ a lemon
  • 2 ½ cups cashew or oat milk (these tend to be creamier so lead to better results)
  • 1 Tbsp maple syrup (I presume you could also use honey, agave or date syrup but I haven't tried those)
  • 1 tsp vanilla extract 
  • 2 cups of rolled oats
  • 1 Tbsp ground flaxseeds/flaxseed meal
  • 2 scoops of unflavored protein powder
  • Big pinch of sea salt
  • Toppings could be fresh blueberries or other fresh fruit, nut butter, coconut or crunchy things like nuts, seeds or granola!


  1. Whiz the first 5 ingredients in a blender until the milk is a beautiful purpley-blue and the blueberries are fully blended. (note that fresh blueberries will work here but don’t create that color and often don’t have as much flavor as the frozen ones do).
  2. Place the next 4 ingredients into a large bowl for mixing. Stir to combine.
  3. Pour the blueberry milk over the top and stir to combine thoroughly.
  4. Cover the container and place in the fridge overnight or put into Ball jar(s) and into the fridge overnight. You can eat this in as soon as 30-60 minutes but it’s so handy to make this in the evening for a gorgeous and delicious breakfast in the morning!
  5. Top with your favorite toppings. IMO, the addition of fresh blueberries is outstanding!
