A creamy, protein-packed overnight oats recipe featuring peanut butter and banana for a quick, nourishing breakfast that’s ready to eat straight from the fridge.

Ingredients

Scale
  • ½ cup (45g) rolled oats (old-fashioned)
  • 1 scoop (about 30g) vanilla whey or plant-based protein powder
  • 2 tablespoons natural creamy peanut butter
  • 1 medium ripe banana, mashed
  • ¾ cup (180ml) milk of choice (dairy or plant-based)
  • ¼ cup (60g) Greek yogurt (optional but recommended)
  • 1 tablespoon chia seeds
  • 1 teaspoon honey or maple syrup (optional)
  • ¼ teaspoon ground cinnamon
  • Pinch of salt

Instructions

  1. Mash the banana in a medium bowl until mostly smooth with a few small lumps remaining.
  2. Add peanut butter, Greek yogurt (if using), and milk to the mashed banana. Stir until smooth and creamy.
  3. Stir in rolled oats, protein powder, chia seeds, ground cinnamon, and salt until thoroughly combined.
  4. Taste and add honey or maple syrup if desired, then mix again.
  5. Transfer the mixture to a clean mason jar or airtight container and seal tightly.
  6. Refrigerate for at least 6 hours or overnight to allow oats and chia seeds to soften and thicken.
  7. In the morning, stir the oats well. Add fresh banana slices, a drizzle of peanut butter, or chopped nuts if desired before serving.

Notes

Use old-fashioned rolled oats for best texture; natural peanut butter blends better; chia seeds help thicken and add fiber; refrigerate 8-12 hours for creamier texture; stir before serving; add splash of milk if too thick or extra oats if too runny; can blend for smoother texture.
