Ingredients
Method
- Add the frozen banana, peanut butter, maple syrup, and milk to a high-speed blender.
- Toss in the protein powder, flaxseed, cinnamon, and ice cubes (if using).
- Blend on high for 45–60 seconds until completely smooth and creamy.
- Stop and scrape down the sides if needed, then blend again for 10 seconds.
- Pour into a chilled glass, garnish with a drizzle of peanut butter or a pinch of cinnamon (optional).
- Serve immediately for the best texture and flavor.
Notes
- For a nut-free version, substitute peanut butter with sunflower seed butter.
- If you don’t have a frozen banana, use a room-temperature banana and add 1 extra cup of ice.
- This smoothie thickens as it sits; add a splash of milk to thin it out if making ahead.
- To make it an "ultra-power" shake, add 1 tablespoon of hemp hearts for extra omega-3s.
- Store leftovers in a sealed mason jar in the fridge for up to 24 hours (shake well before drinking).
