A creamy, high-protein overnight oats recipe featuring peanut butter and banana, perfect for a quick, nourishing breakfast that supports weight loss.

Ingredients

Scale
  • 1/2 cup (45g) rolled oats (old-fashioned)
  • 2 tablespoons natural peanut butter (creamy or chunky)
  • 1 medium banana, sliced
  • 1/3 cup (80g) plain Greek yogurt
  • 1/2 cup (120ml) milk (dairy or plant-based, e.g., almond milk)
  • 1 tablespoon chia seeds (optional)
  • 1 teaspoon honey or maple syrup (optional)
  • 1/2 teaspoon vanilla extract
  • Pinch of salt

Instructions

  1. Combine dry ingredients: In a mixing bowl, add rolled oats, chia seeds, and a pinch of salt. Stir to distribute chia seeds evenly.
  2. Add wet ingredients: Pour in Greek yogurt, milk, and vanilla extract. Mix thoroughly until combined and creamy but slightly loose.
  3. Sweeten gently: Stir in honey or maple syrup if desired for extra sweetness.
  4. Incorporate peanut butter: Add peanut butter and stir well to blend evenly. Add a splash more milk if mixture is too thick.
  5. Transfer to jar: Spoon mixture into a 16 oz mason jar or similar airtight container and smooth the top.
  6. Add banana slices: Layer sliced banana on top of the oats. Optionally mix some slices into the oats.
  7. Seal and refrigerate: Screw the lid on tightly and refrigerate overnight or at least 6 hours.
  8. Ready to eat: In the morning, stir gently to combine flavors. Add extra milk if a thinner consistency is desired. Enjoy chilled or warmed.

Notes

Use old-fashioned rolled oats for best texture; avoid quick oats to prevent mushiness. Stir peanut butter well before measuring. Chia seeds add fiber and help thicken but are optional. Refrigerate at least 6 hours or overnight for best results. Microwave for 20 seconds with milk if a warm serving is preferred. Store leftovers up to 3 days refrigerated. Fresh banana slices can brown; add fresh slices before serving.
