Ingredients

  • Cold coffee (chilled brewed coffee or cold brew)
  • Unsweetened almond milk, oat milk, cashew milk, or skim milk
  • Vanilla or chocolate whey protein powder (or plant-based protein if preferred)
  • Ready-to-drink protein shake (optional, for simpler mixing)
  • Ice (lots of it)
  • Zero-calorie sweetener (stevia, monk fruit, or sucralose), or a small amount of maple syrup/honey
  • Vanilla extract or almond extract (optional)
  • Unsweetened cocoa powder or cinnamon (optional)
  • Sea salt (a tiny pinch to enhance flavor)
  • Sugar-free flavored syrup (caramel, hazelnut, or mocha—optional)

Instructions

  • Brew and chill your coffee. Make a strong batch of hot coffee and let it cool, or use ready-made cold brew. Stronger coffee stands up better to milk and ice.
  • Pick your protein base. Choose 1 scoop of protein powder mixed with 4–8 ounces of unsweetened milk, or use a ready-to-drink protein shake for convenience.
  • Blend or shake the protein. If using powder, add it to your milk in a shaker bottle and shake until smooth and foamy. No clumps means a silkier drink.
  • Sweeten lightly. Add a small amount of zero-calorie sweetener or 1–2 teaspoons of real sweetener. Taste and adjust—start small.
  • Flavor boost. Add 1/4 teaspoon of vanilla extract, a sprinkle of cinnamon, or 1 teaspoon of unsweetened cocoa powder if you want a mocha vibe.
  • Build the glass. Fill a large glass to the top with ice. Pour in 1/2 to 2/3 cup of cold coffee.
  • Top with protein mixture. Slowly pour the protein milk over the coffee and ice. Stir gently to combine.
  • Finish with a pinch of salt. A tiny pinch sharpens flavor and reduces any bitterness without extra sweetener.
  • Taste and tweak. Add more ice, coffee, or sweetener to hit your perfect balance. Enjoy right away.
