Prep Time15 minutes
Cook Time30 minutes
Total Time45 minutes
Servings: 4 servings

Ingredients

  • 1 cup cold brew coffee (unsweetened) or chilled strong brewed coffee
  • 1 scoop low-carb protein powder (whey isolate, egg white, or plant-based; vanilla or unflavored)
  • ½ cup unsweetened almond milk (or coconut milk, macadamia milk)
  • 1–2 tablespoons heavy cream or full-fat coconut cream for extra richness
  • 1–2 teaspoons MCT oil or 1 tablespoon almond butter (optional, for healthy fats and satiety)
  • 1–2 teaspoons erythritol, allulose, or liquid stevia (to taste)
  • ½ teaspoon vanilla extract (optional)
  • Pinch of sea salt (enhances flavor)
  • 1 cup ice (adjust for thickness)
  • Optional add-ins: cacao powder, cinnamon, collagen peptides, sugar-free caramel or mocha flavor drops

Instructions

  • Chill your coffee. Use cold brew or brewed coffee cooled in the fridge. Cold liquid helps the shake blend thick and frosty.
  • Add liquids to the blender first. Pour in coffee and unsweetened milk. This prevents clumping when you add protein powder.
  • Add protein and fats. Add your protein powder, heavy cream or coconut cream, and MCT oil or nut butter if using.
  • Sweeten and season. Add your preferred sweetener, vanilla extract, and a small pinch of salt.
  • Ice last. Add ice on top so the blades can pull it down evenly.
  • Blend until smooth. Start low, then increase to high for 20–30 seconds. Scrape down the sides if needed and blend again until creamy.
  • Taste and adjust. Add more sweetener for dessert vibes, more ice for thickness, or a splash of milk to thin.
  • Serve immediately. Pour into a tall glass. Top with a dusting of cinnamon or a drizzle of sugar-free syrup if you like.
