How to make Blueberry Overnight Oats

  1. Combine.  Add oats, maple syrup, salt, flaxseed, lavender paste (optional), and non-dairy milk to a sealable container.  Mix well.
  2. Add blueberries. Add frozen wild blueberries to the oat mixture and stir to combine.  We like to use Wild frozen Blueberries.  They are insanely sweet, available at Costco and most large retailers, keep for what seems like forever since they are frozen, are available year round, and because they are wild blueberries, they have more health benefits that an average blueberry.  
  3. Let set.  Cover and let the oats set in the fridge overnight or for at least 4 hours.  
  4. Add cashew butter.  Remove from the fridge and uncover.  We like to heat the oats up for 1 minute at this point.  Heated oats are a personal preference, but it does help dissolve the cashew butter.  Depending on if you heat the oats up or not, you will add the cashew butter after heating them or right out of the fridge.  Stir well to fully incorporate the cashew butter.
  5. Top with your favorite toppings and enjoy.  We like these topped with blueberry jam, granola, fresh blueberries, and a dollop of coconut whip cream!

Substitution Options

All substitution options are a 1:1 replacement unless noted otherwise

Oats:  Any oats can be used, regular, old fashioned, or quick cook, just not steel cut unless they are quick cook steel cut oats.  Be aware – not all oats are gluten free.

Lavender: No substitute for this, but it is optional and can be omitted.

Maple Syrup: Agave or honey can be used.  

Non-Dairy Milk:  Any milk can be used, but my favorites are Organic Valley Lactose Free Half and Half, Flax protein milk, cashew milk, and coconut milk.

Blueberries:  Any frozen or fresh blueberries can be used, but we do love our frozen Wyman’s Wild Blueberries!

Flaxseed: Chia seeds can be used in place of flaxseed.  You can get flax seeds here and chia seeds here.

Salt:  No substitution for this – use the salt!

Cashew Butter:  This can be omitted or you can use ½ scoop of vanilla protein powder or vanilla yogurt in its place.


Fun Fact! 

Wild Blueberries differ from regular blueberries in many ways, the most obvious being that they grow naturally and are not planted.  In many cases the wild blueberry crops have grown for thousands of years.  Wild blueberries are also much smaller in size compared to regular blueberries. Also, they grow on bushes that only reach calf height, and the bushes grow on rocky terrain.  Because of this, to cultivate wild blueberries, farmers must use a tool that pulls the blueberries off the bush in an upward motion, similar to an upside down rake.  Wild blueberries have 2x the antioxidants than regular blueberries due to elevated levels of anthocyanin.  This super concentration of anthocyanin is thought to be a result of the wild berries adapting to the cold and harsh climates of Maine and Canada, as anthocyanin is also responsible for how hardy or tough a fruit is.  (Source
