Servings1 (about 1 heaping cup)


  • 1/2 ripe banana
  • 1/2 cup old-fashioned rolled oats (gluten-free if desired)
  • 1/2 cup dairy-free milk
  • 2 tsp. chia seeds
  • 2 tsp. cacao powder (or cocoa powder)
  • 1-2 Tbsp. pure maple syrup (I use about 1 1/2)
  • 2 Tbsp. creamy, natural peanut butter (or more to taste)


  • 1/2 tsp. vanilla extract, 1/8 tsp. almond extract, ground cinnamon, etc.


  • In a medium mixing bowl, mash banana.
  • Add oats, milk, chia, cacao, and maple syrup. Stir well to combine.
  • Add peanut butter. (I like to drop mine in small dollops so there are clumps of peanut butter.) Gently stir to combine.
  • Transfer mixture to a mason jar or small bowl. Then lightly press down with a spoon to make sure oats are fully immersed in the liquid.
  • Cover and refrigerate at least 5 hours or overnight.


Recipe yields about 1 heaping cup. This makes one large serving, or two smaller servings.
Serving: Enjoy as is, or top with fresh berries, sliced banana (I use the leftover 1/2 banana for serving), ground cinnamon, additional peanut butter, cacao nibs, etc.
