How do you make good overnight oats?
First decide how many servings of oatmeal you'd like to make. We recommend to meal prep up to 4 jars to save time during busy mornings.
NOTE: The blueberries can be added during the initial mix but I find they taste better added right before serving.
Measure out the rolled oats, ground flax seeds, chia seeds, protein powder and peanut butter powder into each jar and stir to combine them.
Add the chopped dates and walnuts to the jars and stir again. This will help to coat the dates with powder and help them to disperse more evenly once the liquid is added.
Add the almond milk, or your choice of milk and stir to combine. Place a lid on the jar and store in the fridge for at least 2 hours or up to 5 days.
This oatmeal can be served cold right out of the fridge or heated up on the stove or in the microwave. Right before you are ready to serve, top with frozen or fresh blueberries.
TIP: If the oatmeal is too thick, add more milk to thin it out to your liking. Also, if the oatmeal isn't sweet enough you can add a sweetener such as maple syrup, honey, stevia or coconut sugar.
