Ingredients

Scale
  • ½ cup (45 g) rolled oats (old-fashioned)
  • 2 tablespoons (32 g) peanut butter, creamy or chunky
  • 1 medium ripe banana, mashed
  • 1 scoop (about 30 g) vanilla protein powder (whey or plant-based)
  • ¾ cup (180 ml) milk of choice (dairy, almond, oat, or soy)
  • ¼ cup (60 g) plain Greek yogurt (optional but recommended)
  • 1 tablespoon (12 g) chia seeds
  • 1 teaspoon honey or maple syrup (optional)
  • ¼ teaspoon ground cinnamon
  • Pinch of salt

Instructions

  1. Mash 1 ripe banana in a medium bowl with a fork until mostly smooth but still a bit chunky (about 2 minutes).
  2. Stir in 2 tablespoons peanut butter until evenly combined with the banana (1 minute).
  3. Add ½ cup rolled oats, 1 tablespoon chia seeds, 1 scoop vanilla protein powder, ¼ teaspoon ground cinnamon, and a pinch of salt. Stir gently to combine (2 minutes).
  4. Pour in ¾ cup milk and ¼ cup plain Greek yogurt. Stir well until evenly moistened. Add 1 teaspoon honey or maple syrup if desired (2 minutes).
  5. Spoon the mixture into a mason jar or airtight container and seal tightly (1 minute).
  6. Refrigerate for at least 6 hours or overnight to allow oats and chia seeds to soften and thicken (6+ hours).
  7. In the morning, stir the oats well. Add a splash of milk if too thick. Top with sliced banana, a drizzle of peanut butter, or crushed nuts if desired (1-2 minutes).

Notes

Use ripe bananas for best sweetness and creaminess. Adjust milk quantity to achieve desired thickness. Protein powder choice affects texture; vanilla whey or pea protein blends work best. Add honey or maple syrup last to control sweetness. For vegan version, use plant-based protein powder, dairy-free milk, and yogurt alternatives. Store leftovers in fridge up to 3 days. Warm briefly in microwave if preferred warm.
