A quick and easy high-protein overnight oats recipe combining rolled oats, peanut butter, banana, and Greek yogurt for a creamy, filling, and nutritious breakfast that can be prepped the night before.

Ingredients

Scale
  • 1/2 cup rolled oats (45g)
  • 2 tablespoons peanut butter (32g), creamy or natural
  • 1 medium banana, mashed
  • 1/2 cup Greek yogurt (120g), full-fat or low-fat
  • 1/2 cup milk (120ml), dairy or plant-based
  • 1 tablespoon chia seeds (12g), optional
  • 1 teaspoon honey or maple syrup (7g), optional
  • 1/4 teaspoon cinnamon
  • 1/2 teaspoon vanilla extract, optional

Instructions

  1. Mash 1 ripe banana in a medium bowl with a fork until mostly smooth but still a bit chunky.
  2. Add 2 tablespoons peanut butter and mix with the banana until well combined. Microwave for 10 seconds if peanut butter is stiff.
  3. Add 1/2 cup Greek yogurt and 1/2 cup milk of choice. Stir gently to combine until creamy but pourable.
  4. Mix in 1/2 cup rolled oats and 1 tablespoon chia seeds. Stir thoroughly to coat oats and start thickening.
  5. Sprinkle 1/4 teaspoon cinnamon, 1/2 teaspoon vanilla extract, and 1 teaspoon honey or maple syrup if desired. Stir again.
  6. Spoon mixture evenly into 2 small mason jars or airtight containers and seal tightly.
  7. Refrigerate for at least 6 hours or overnight to allow oats and chia seeds to soak and soften.
  8. In the morning, stir the oats. Add extra milk if too thick. Optionally top with sliced banana, chopped nuts, or a drizzle of peanut butter before serving.

Notes

Use rolled oats for best texture; instant oats can become mushy. Chia seeds are optional but help thicken and add fiber. Adjust milk quantity for desired creaminess. Avoid soaking longer than 24 hours to prevent mushy texture. Add crunchy toppings like nuts or granola just before serving for texture contrast. Can substitute peanut butter with almond or sunflower seed butter. Vegan option available by using plant-based yogurt, milk, and maple syrup instead of honey.
