Want to make the Smoothie King Original High Protein Banana at home? This homemade copycat recipe uses easy ingredients you can find anywhere and tastes just like the store version. It is simple, protein-packed, and saves you money.
How I Figured Out This Recipe
I first tried recreating the Original High Protein Banana and realized it lacked that smooth banana flavor and perfect creaminess. The blender straight-up buzzed through everything, but the taste wasn’t quite right.
Then I tried using a really ripe banana, Greek yogurt, and a tiny touch of honey. That combo nailed the sweetness, banana-rich flavor, and thick beauty—in a way that tasted just like Smoothie King.
Original High Protein Banana Ingredients
- 1 large very ripe banana: gives that strong banana sweetness and real flavor.
- 2 scoops vanilla or banana protein powder: packs in protein and boosts banana taste.
- 1 cup unsweetened almond milk: keeps it smooth and lowers calories.
- ½ cup plain Greek yogurt: adds thick creaminess and extra protein.
- 1 tsp honey (optional): my secret for a gentle sweetness.
- ¼ tsp vanilla extract: amplifies that warm flavor.
- 1 cup ice: makes it cold and thick.
How to Make Original High Protein Banana (Copycat)
- Peel and slice your ripe banana into the blender.
- Add almond milk, protein powder, Greek yogurt, honey, and vanilla extract.
- Toss in the ice.
- Blend until smooth, thick, and creamy.
- Taste and fix: Too thick? Add a bit more almond milk. Not sweet enough? Stir in a little more honey.

Why This Tastes Like the Smoothie King Version
- Ripe banana gives the natural banana flavor from the real smoothie.
- Protein powder keeps it high‑protein and carries the flavor.
- Greek yogurt adds creaminess and protein, just like theirs.
- A touch of honey smooths the sweetness without overpowering.
- That cold, thick texture comes from blending ice and creamy base.
Easy Tips and Swaps
- Vegan version: use dairy‑free yogurt and a vegan protein powder.
- Want more green? Add a handful of spinach—it won’t change the taste.
- To boost fiber, add a tablespoon of chia seeds or oats.
- No honey? Try maple syrup or a date for sweetness.
How to Store Your Smoothie
- In the Fridge: Keep leftovers in a sealed jar for up to 24 hours. Give it a good stir or shake before drinking—it may thicken a bit.
- In the Freezer: Pour into ice cube trays or jars, freeze, and then blend with a splash of almond milk for a frozen treat.
