Ingredients

  • 1/2 cup Rolled oats
  • 1 tablespoon Ground flaxseed
  • 1/2 teaspoon Ground cinnamon
  • 1 teaspoon Date sugar optional, for extra sweetness
  • 3/4 cup Vanilla oat milk sub any dairy free milk of your choice
  • 1 tablespoon peanut butter
  • 1 tablespoon Date syrup
  • 1/2 Banana sliced, plus more for topping
  • 1/4 cup Walnuts roughly chopped

Instructions

  • Add the rolled oats, ground flaxseed, cinnamon, and date sugar to a mason jar that has a lid.
  • Now add in the wet Ingredients: gently pour in the vanilla oat milk, date syrup, and add the peanut butter. If you're using protein powder, add it here too.
  • Mash the Banana: Mash half of the banana with a fork and stir it into the oats mixture for extra flavor and creaminess. Reserve the other half for topping later.
  • Mix everything together until the oats are evenly coated with the liquid and peanut butter.
  • Cover the jar with the lid and let it sit in the fridge for at least 6 hours or overnight so that the oats can soak up all of the liquids and get tender.
  • Toppings: In the morning, give the oats a quick stir. Slice the remaining banana and top your oats with the banana slices, strawberries, raspberries, chopped walnuts, and an extra drizzle of date syrup or peanut butter if you want.
  • Enjoy!

Equipment

  • Mason jar airtight container with a lid
  • Small bowl (optional, for mashing banana)

Notes

  • Add a scoop of vanilla protein powder for even more protein if desired. 
  • If the oats are too thick in the morning, you can add a little more oat milk to loosen them up.
  • You can also swap walnuts for any other nut or seed of your choice.
  • For an extra boost, you can top with chia seeds or hemp hearts.
