Units Scale

For banana bread overnight oats base:

  • 1 cup old fashioned rolled oats
  • 1 TBS chia seeds, or ground flax (see notes to omit)
  • Pinch of salt
  • 1/2 of a small to medium banana, mashed
  • 1/3 cup plain unsweetened nondairy yogurt (not Greek-style)
  • 1 cup unsweetened plain oat milk
  • 1 TBS maple syrup, optional if you prefer a sweeter recipe
  • 1/4 tsp nutmeg
  • 1/4 tsp cinnamon
  • 1/4 cup walnuts, optional

For banana split toppings:

  • 2 small bananas, peeled and sliced lengthwise into two pieces
  • Mixed berries of choice (I used strawberries and blueberries)
  • 2 TBS unsweetened shredded coconut

For tahini chocolate sauce:

  • 2 TBS cocoa powder, dutch process if possible
  • 2 TBS runny tahini paste
  • 1 TBS maple syrup
  • 2 TBS plain oat milk
  • Pinch of salt


  1. Begin the night before you plan to serve this recipe (or at least 2-3 hours in advance). Combine all ingredients for overnight oats into a medium sized, sealable container (reminder: this makes enough for at least two servings). Let sit in the fridge - the oats will naturally soften and the chia seeds will help absorb liquid for a perfectly chewy texture.
  2. In two shallow bowls, place sliced banana halves down. Spoon half of the oats mixture inside each, and top with berries and coconut.
  3. In a small bowl, combine all ingredients for tahini chocolate sauce. Drizzle over each bowl and enjoy right away.


This recipe will keep in the fridge for 2-3 days, but know that the bananas will soften over time. The oats base is of course delicious on its own, I mainly included the sundae elements for some fun and prettier photos.

To make this recipe without chia or flax seeds, simply reduce the amount of milk to 3/4 cup.
