A quick and easy overnight oats recipe packed with protein, peanut butter, and banana for a nourishing and comforting breakfast that’s perfect for busy mornings.

Ingredients

Scale
  • 1/2 cup rolled oats (45g)
  • 1 scoop protein powder (about 30g), vanilla flavored whey or plant-based
  • 2 tablespoons natural peanut butter (32g)
  • 1 medium banana, mashed
  • 3/4 cup milk of choice (180 ml)
  • 1/4 cup Greek yogurt (60g)
  • 1 tablespoon chia seeds (12g), optional
  • 1 teaspoon honey or maple syrup (7g), optional
  • 1/2 teaspoon vanilla extract (2.5 ml)
  • Pinch of cinnamon, optional

Instructions

  1. Mash the banana in a medium bowl using a fork until smooth with a few small chunks remaining, about 1 minute.
  2. Add rolled oats, protein powder, and chia seeds to the bowl. Stir gently to combine with the mashed banana.
  3. Mix in the peanut butter and Greek yogurt. Soften peanut butter beforehand if firm by letting it sit at room temperature or microwaving for 10 seconds.
  4. Pour in the milk, vanilla extract, cinnamon, and honey or maple syrup if using. Stir until the mixture is smooth and creamy with no dry pockets.
  5. Divide the mixture evenly into two mason jars or airtight containers and screw the lids on tightly.
  6. Refrigerate overnight for at least 6 hours, preferably 8–10 hours, to allow oats and chia seeds to absorb liquid and thicken.
  7. In the morning, stir the oats well. If too thick, add a splash of milk to loosen. Top with sliced banana, a drizzle of peanut butter, or chopped nuts if desired.

Notes

Use rolled oats for best texture; instant oats may become mushy. Stir well before refrigerating to avoid clumps. Adjust sweetness after tasting the banana. If peanut butter separates overnight, stir to reincorporate. Consume within 3 days for best freshness. For dairy-free, substitute Greek yogurt with coconut or almond yogurt and use plant-based milk.
