Want to make the Smoothie King Slim‑N‑Trim Chocolate 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
I started with all the chocolate flavor but it came out too thin and watery. It tasted okay, but it didn’t have that thick, shake-like texture I remember from Smoothie King.
Then I added half a frozen banana and a spoon of peanut butter. That gave it both creaminess and richness, making it feel indulgent yet still light enough to be “Slim‑N‑Trim.” It hit that perfect balance!
Slim‑N‑Trim Chocolate Ingredients
- 2 cups unsweetened almond milk: gives a smooth, low-calorie base.
- 1 frozen small banana: adds creaminess and natural sweetness.
- 1 scoop chocolate protein powder: delivers rich chocolate flavor and protein.
- 1 tbsp cocoa powder: deepens the chocolate taste.
- 1 tbsp creamy peanut butter: adds a subtle nutty richness and extra creaminess.
- 1 cup ice: makes it cold, thick, and refreshing.

Easy Tips and Swaps
