A simple, nutritious, and quick overnight oats recipe combining ripe banana, peanut butter, and rolled oats for a creamy and satisfying breakfast.

Ingredients

Scale
  • ½ cup (45g) old-fashioned rolled oats
  • 1 medium ripe banana, mashed (about 100g)
  • 2 tablespoons (32g) creamy peanut butter
  • Optional: 2-3 tablespoons (30-45 ml) milk (dairy or plant-based)
  • Optional: pinch of cinnamon
  • Optional: drop of vanilla extract
  • Optional: sprinkle of chia seeds or flaxseed

Instructions

  1. Mash 1 medium ripe banana with a fork in a bowl or jar until mostly smooth, about 1-2 minutes.
  2. Stir in 2 tablespoons (32g) of creamy peanut butter until evenly combined with the banana.
  3. Add ½ cup (45g) old-fashioned rolled oats and stir well to coat all the oats.
  4. If desired, add 2-3 tablespoons (30-45 ml) of milk and mix until combined.
  5. Optionally add a pinch of cinnamon or a drop of vanilla extract and stir gently.
  6. Cover the jar or bowl and refrigerate overnight or for at least 6 hours.
  7. The next morning, stir the oats well. If too thick, add a splash more milk to reach preferred consistency.
  8. Serve topped with sliced bananas, nuts, or a drizzle of honey if desired.

Notes

If peanut butter is thick, warm slightly before mixing for smoother blend. Mashing banana well creates creamier texture. Use ripe bananas for natural sweetness. Refrigerate at least 6 hours for best texture. Add milk to adjust thickness before serving. Store leftovers up to 3 days refrigerated.
