Ingredients
  

  • Old-fashioned rolled oats (1/2 cup) – for hearty texture and slow-release energy
  • Milk of choice (2/3 to 3/4 cup) – dairy or unsweetened almond, soy, or oat milk
  • Greek yogurt (1/3 cup) – boosts protein and creaminess
  • Protein powder (1 scoop, vanilla or unflavored) – whey or plant-based
  • Peanut butter (1–2 tablespoons) – creamy or natural for classic flavor
  • Banana (1 small to medium, mashed or sliced) – natural sweetness and potassium
  • Chia seeds (1 teaspoon, optional) – thickens and adds omega-3s
  • Maple syrup or honey (1–2 teaspoons, optional) – for extra sweetness if needed
  • Vanilla extract (1/4 teaspoon, optional) – rounds out flavor
  • Pinch of salt – brightens everything
  • Toppings (optional) – sliced banana, chopped peanuts, cacao nibs, cinnamon, or a drizzle of peanut butter

Method
 

  1. Mash or slice the banana. For a smoother, sweeter base, mash it. For more texture, slice half and save the rest for topping.
  2. Mix the wet ingredients. In a jar or bowl, whisk milk, Greek yogurt, peanut butter, vanilla, and sweetener until smooth. If using protein powder, whisk it in now.
  3. Add dry ingredients. Stir in oats, chia seeds (if using), and a pinch of salt. Fold in the banana.
  4. Adjust consistency. The mixture should be slightly loose. Add a splash more milk if it feels too thick; the oats and chia will absorb moisture overnight.
  5. Cover and chill. Seal the jar or bowl and refrigerate for at least 4 hours, preferably overnight.
  6. Stir and serve. In the morning, give it a good stir. Add a little milk if you want it looser.
  7. Top it off. Finish with sliced banana, a drizzle of peanut butter, and a sprinkle of cinnamon or chopped peanuts for crunch.
