A creamy, satisfying overnight oats recipe packed with protein, peanut butter, and banana, perfect for an easy weight loss breakfast that keeps you full all morning.

Ingredients

Scale
  • ½ cup (45g) rolled oats (old-fashioned preferred)
  • 2 tablespoons peanut butter (creamy or natural, unsweetened if possible)
  • 1 medium ripe banana, mashed
  • 1 scoop (about 30g) protein powder (vanilla or unflavored whey or plant-based)
  • ½ cup (120ml) milk of choice (dairy or unsweetened plant-based like almond, oat, or soy)
  • 1 tablespoon chia seeds (optional)
  • 1 teaspoon honey or maple syrup (optional)
  • ½ teaspoon vanilla extract (optional)
  • A pinch of cinnamon (optional)

Instructions

  1. Mash the banana in a bowl or directly in your jar until smooth but still a bit chunky (about 1-2 minutes).
  2. Add rolled oats, chia seeds (if using), protein powder, and cinnamon to the mashed banana. Stir well to combine evenly.
  3. Pour in milk and vanilla extract. Stir thoroughly so oats are fully coated and protein powder blends in without clumps.
  4. Stir in 1 tablespoon peanut butter into the mixture. Reserve the other tablespoon for swirling on top the next morning.
  5. Add honey or maple syrup if desired and mix again.
  6. Seal the jar or container and refrigerate for at least 6 hours, ideally 8–10 hours for optimal soaking.
  7. The next morning, stir the oats well and add the reserved peanut butter on top or swirl it in for a creamy finish.
  8. If the oats feel too thick, add a splash of milk and stir to loosen before serving.

Notes

Use old-fashioned rolled oats to avoid mushiness. Adjust milk quantity to achieve preferred texture. Stir protein powder thoroughly to prevent lumps. Reserve some peanut butter for topping to preserve flavor and texture. Ripe bananas add natural sweetness and soften texture. Can be stored up to 3 days refrigerated; stir in milk before serving if thickened. For vegan version, use plant-based protein powder and non-dairy milk.
