Smoothie Kin Gladiator Chocolate Coffee is a creamy, high-protein smoothie made with cold brew, banana, and chocolate protein powder. This homemade copycat version mirrors the Smoothie King original in texture and flavor, delivering a rich chocolate taste with a subtle caffeine boost. Great for post-workout fuel or a quick breakfast.
Ingredients Needed for Gladiator Chocolate Coffee (Copycat)
- ¾ cup cold brew coffee (unsweetened): Provides mild caffeine and a smooth, roasted flavor just like Smoothie King’s cold brew.
- 1 medium ripe banana (frozen): Adds natural sweetness, creaminess, and fiber—mimicking their base texture.
- 1 scoop chocolate whey protein powder (25g): Replaces their Gladiator® Chocolate Protein blend with a similar rich chocolate flavor and high protein.
- 1 scoop unflavored or vanilla whey protein (20–25g): Balances macros and builds the full 45–46g protein target.
- 1 tbsp unsweetened cocoa powder (optional): Boosts the chocolate profile without adding sugar.
- 1 cup ice cubes: Helps chill and thicken the smoothie to that signature frozen consistency.
- Pinch of sea salt (optional): Slightly enhances the chocolate-coffee flavor balance, especially since the original has 500mg sodium.
How To Make Gladiator Chocolate Coffee (Copycat Recipe)
- Chill the Cold Brew: Make sure your coffee is fully chilled before blending for best texture and flavor.
- Freeze the Banana: Use a frozen banana for a thicker, creamier consistency that mirrors Smoothie King’s texture.
- Add to Blender: Combine cold brew, banana, chocolate protein powder, unflavored protein, cocoa (if using), ice, and a pinch of salt.
- Blend Until Smooth: Blend on high speed for 30–45 seconds until the smoothie is thick, creamy, and frothy.
- Adjust to Taste: Add more coffee for a stronger brew, or more ice for a colder, thicker shake.

Why This Homemade Version Matches the Original
This copycat was built to match the Smoothie King Gladiator Chocolate Coffee in both taste and performance. Here’s how:
- Uses cold brew + banana + chocolate protein just like the original formula
- Hits nearly identical macros (45g protein, 26g carbs, ~300 calories)
- No added sugar, just like Smoothie King
- Low-fat, high-protein profile using two clean whey scoops
- Optional cocoa + salt enhance the chocolate and match Smoothie King’s sodium balance
No commercial Gladiator® blend needed—this version nails the flavor and nutrients using real, accessible ingredients.
Recipe Tips & Smart Variations
- Make It Dairy-Free: Use a plant-based chocolate protein and almond milk cold brew. You’ll still hit similar macros with the right scoop.
- Low-Carb Version: Use only ½ banana and replace the rest with ½ avocado + monk fruit for sweetness.
- Mocha Boost: Add 1 tsp unsweetened cocoa + ½ tsp instant espresso for deeper mocha flavor.
- Smoother Texture Tip: If you don’t freeze the banana, add 1–2 extra ice cubes to keep it thick.
- Salt Balance Tip: A small pinch of sea salt sharpens the chocolate flavor and balances the cold brew.
How To Store This Gladiator Chocolate Coffee Smoothie
In the Fridge: Store up to 24 hours in a sealed container. Shake before drinking—may separate slightly but still creamy.
In the Freezer: Freeze in an airtight container for up to 2 months. Thaw overnight in the fridge, then re-blend for original texture.
