This creamy overnight peanut butter banana protein oats recipe is a game-changer for busy mornings. With just five minutes of prep, you get a thick, luscious, and protein-packed breakfast that tastes like a peanut butter banana smoothie in oatmeal form.

Ingredients

Scale
  • 1 cup (90g) rolled oats
  • 1 cup (240ml) milk of choice (whole milk, oat milk, or almond milk)
  • 2 tablespoons (32g) creamy peanut butter
  • 1 medium ripe banana (about 120g)
  • 1 scoop (about 30g) vanilla or unflavored protein powder
  • 1 tablespoon (12g) chia seeds (optional)
  • 1 tablespoon (15ml) maple syrup or honey (optional)
  • Pinch of salt
  • Optional toppings: sliced banana, extra peanut butter drizzle, chopped peanuts, dark chocolate chips, or cinnamon

Instructions

  1. Mash the banana thoroughly in a medium mixing bowl until smooth with no large chunks.
  2. Add the milk, peanut butter, and maple syrup (if using). Whisk or stir vigorously until the peanut butter is fully incorporated and the mixture is smooth.
  3. In a separate small bowl, combine the rolled oats, protein powder, chia seeds, and salt. Stir until evenly distributed, breaking up any clumps.
  4. Pour the dry ingredients into the wet mixture. Stir thoroughly until no dry oats remain and the mixture looks uniform. It will seem thin at this point.
  5. Divide the mixture evenly into two mason jars or airtight containers, leaving about an inch of headspace. Screw the lids on tightly.
  6. Refrigerate for at least 6 hours, but ideally 8-12 hours or overnight.
  7. In the morning, stir the oats once. They should be thick and creamy. If too thick, stir in a splash of milk. Add desired toppings and serve cold or at room temperature.

Notes

Mash the banana thoroughly to avoid lumps. Mix protein powder with a little milk first to prevent clumps. Don’t oversweeten—the banana adds natural sweetness. Use wide-mouth jars for easier stirring. Let the oats sit at room temperature for 10 minutes before eating to enhance flavor. This recipe can be doubled or quadrupled for weekly meal prep. Oats keep in the fridge for up to 5 days; do not freeze.
