These creamy peanut butter banana overnight oats are a quick, no-cook breakfast that tastes like comfort. Made with simple pantry ingredients, they’re perfect for busy mornings and can be prepped in just 5 minutes.

Ingredients

Scale
  • ½ cup (50g) old-fashioned rolled oats
  • ½ cup (120ml) milk of your choice (whole milk, oat milk, almond milk, etc.)
  • ¼ cup (60g) plain Greek yogurt (full-fat or 2%)
  • 1 medium ripe banana (the riper, the better)
  • 2 tablespoons (32g) creamy peanut butter (natural, well-stirred)
  • 1 tablespoon (15ml) maple syrup or honey
  • 1 tablespoon (12g) chia seeds (optional but recommended)
  • Pinch of salt
  • For topping (optional): sliced banana, drizzle of peanut butter, chopped peanuts, dark chocolate chips, cinnamon

Instructions

  1. Mash the banana: Peel the ripe banana and place it in a medium bowl. Mash with a fork until mostly smooth with a few small lumps.
  2. Add the wet ingredients: To the mashed banana, add the milk, Greek yogurt, peanut butter, and maple syrup. Whisk or stir vigorously until the peanut butter is fully incorporated (about 30 seconds).
  3. Stir in the dry ingredients: Add the rolled oats, chia seeds (if using), and a pinch of salt. Stir until everything is evenly combined. The mixture will look thin and soupy—that’s normal.
  4. Transfer to jars: Divide the mixture evenly between two 16-ounce (500ml) jars or one large jar. Leave about an inch of space at the top for toppings and expansion.
  5. Refrigerate overnight: Put the lids on tightly and refrigerate for at least 6 hours, preferably 8 to 12 hours. Overnight is perfect.
  6. Add toppings in the morning: When ready to eat, stir the oats first. Top with sliced banana, a drizzle of warm peanut butter, chopped peanuts, chocolate chips, or a dusting of cinnamon. Eat cold or let sit at room temperature for 10 minutes.

Notes

Use old-fashioned rolled oats, not quick oats, for the best texture. Mash the banana thoroughly to avoid brown chunks. Don’t skip the salt—it enhances the flavors. Stir before eating to redistribute chia seeds. Let the oats sit at room temperature for 10-15 minutes to loosen up. Seal jars tightly to prevent absorbing fridge odors. These keep in the fridge for up to 5 days, with best texture on days 1-3. For a warm version, microwave in 30-second bursts with a splash of milk.
