Want to make the Smoothie King Slim‑N‑Trim Vanilla at home? This homemade copycat recipe uses easy ingredients you can find anywhere and tastes just like the store version. It is simple, healthy, and saves you money.
How I Figured Out This Recipe
When I first blended it, it was too watery and the vanilla taste felt flat. I realized Smoothie King balances flavor by using frozen base and a sweet thickener.
I solved it by using half a frozen banana for creaminess and a touch of honey to lift the vanilla. That combo nailed the flavor and texture I loved from the real thing!
Slim‑N‑Trim Vanilla Ingredients
- 2 cups unsweetened almond milk: keeps the smoothie smooth and low-calorie.
- 1 small frozen banana: makes it creamy and adds natural sweetness.
- 1 scoop vanilla protein powder: gives that rich vanilla flavor and protein boost.
- 1 tsp honey or maple syrup: lifts the vanilla taste without overpowering.
- 1 tsp vanilla extract: deepens the pure vanilla flavor.
- 1 cup ice: ensures it’s cold, thick, and refreshing, like the original.

Why This Tastes Like the Smoothie King Version

- Frozen banana makes it thick and creamy, like the store smoothie.
- Honey (or maple syrup) lifts sweetness just enough without adding sugar bombs.
- Ice keeps it chilled and refreshes the drink.
Easy Tips and Swaps
- For extra creaminess: swap almond milk for oat milk or add a spoon of Greek yogurt.
- For low-sugar: skip banana, use stevia instead of honey, and extra ice.
- For dairy-free: it already is—just make sure your protein powder is plant-based.
- Want vanilla bean flavor? scrape half a vanilla bean into the blender instead of extract.
How to Store Your Smoothie
- In the Fridge: Pour into a sealed jar. Keep it up to 24 hours. Shake well before drinking—the ingredients might settle.
- In the Freezer: Freeze leftover smoothie in ice‑cube trays. Later, blend the cubes with a splash of almond milk to bring it back to life.
