Ingredients

  • Coffee base: Cold brew, iced Americano, chilled espresso, or leftover brewed coffee.
  • Protein sources: Whey or plant-based protein powder (vanilla, chocolate, caramel, or unflavored)
  • Ready-to-drink protein shakes (e.g., vanilla or mocha)
  • Greek yogurt (plain or vanilla)
  • Collagen peptides (unflavored)
  • Milk options: dairy milk, ultra-filtered milk, soy milk, pea milk, or chocolate milk
  • Flavor boosters: Cinnamon, cocoa powder, vanilla extract, caramel extract, maple syrup, honey, or zero-cal sweeteners.
  • Texture add-ins: Ice, half a frozen banana, nut butter, or sugar-free syrups.
  • Tools: Shaker bottle with whisk ball, blender (optional), mason jar with lid, measuring cup, and spoon.

Instructions

  • Pick your base. Use 6–8 ounces of strong cold brew, two shots of espresso over ice, or chilled brewed coffee. Stronger coffee holds up better to protein and milk.
  • Choose your protein format. Fastest: Pour a ready-to-drink protein shake over ice and add coffee.
  • Most flexible: Mix protein powder with milk or water, then add coffee.
  • Creamiest: Blend milk with Greek yogurt, then stir in coffee.
  • Easiest to dissolve: Stir collagen directly into hot or room-temp coffee, then chill or add ice.
  • Mix it right. If using powder, combine it with room-temperature or slightly warm liquid first to prevent clumps. Shake 20–30 seconds until smooth. Then pour over ice and add coffee.
  • Balance the flavors. Start with 1 scoop of protein powder or 8–11 ounces of a protein shake. Add 2–4 ounces of milk if needed. Taste and adjust sweetness with 1–2 teaspoons of maple syrup or your preferred sweetener.
  • Add flavor boosters. A pinch of cinnamon, a dash of vanilla, or a teaspoon of cocoa can make it taste like a café drink without much sugar.
  • Finish with ice and stir. Fill your glass with ice, pour everything together, and stir or shake once more for a smooth finish.
