Prep Time15 minutes
Cook Time30 minutes
Total Time45 minutes
Servings: 4 servings

Ingredients

  • Banana: Preferably frozen for creaminess.
  • Rolled oats or quick oats: Either works; rolled oats give more texture.
  • Greek yogurt: Whole milk or 2% for extra calories and protein.
  • Milk: Dairy or a high-protein alternative like soy milk.
  • Peanut butter: Or almond/cashew butter if you prefer.
  • Honey or maple syrup: Optional for extra sweetness.
  • Chia seeds or ground flaxseed: Optional for fiber and healthy fats.
  • Cinnamon and vanilla extract: Optional for flavor.
  • Ice: Optional if you want it extra thick and cold.
  • Pinch of salt: Optional to enhance flavors.

Instructions

  • Freeze your banana: Peel, slice, and freeze the banana ahead of time for a thicker, creamier smoothie. If you’re in a rush, use a fresh banana and add a handful of ice.
  • Soften the oats (optional): For a smoother blend, soak the oats in a little milk for 5–10 minutes. This step is optional but helps if you don’t like any graininess.
  • Add liquids first: Pour 1 to 1¼ cups milk into the blender. This prevents oats and nut butter from sticking to the bottom.
  • Layer the rest: Add ½ cup Greek yogurt, ½ cup oats, 1 frozen banana, and 1–2 tablespoons peanut butter.
  • Flavor boosters: Add ½ teaspoon cinnamon, ½ teaspoon vanilla extract, and a small pinch of salt. Drizzle in 1–2 teaspoons honey if you want it sweeter.
  • Blend until smooth: Start low, then blend on high for 30–45 seconds. Add a few ice cubes if you want it thicker or more milk if it’s too thick.
  • Taste and adjust: Need more sweetness? Add a touch of honey. Want more calories? Add another spoon of peanut butter or a splash of cream.
  • Serve immediately: Pour into a large glass or shaker bottle. For extra calories and crunch, top with granola or a drizzle of peanut butter.
