Total Time45 minutes
Servings: 4 servings

Ingredients

  • Cold coffee: 3/4 to 1 cup brewed coffee, cooled (or cold brew for smoother flavor)
  • Milk: 1/2 to 3/4 cup (dairy, almond, oat, soy, or your favorite)
  • Protein powder: 1 scoop (whey, pea, or blend; vanilla or unflavored works best)
  • Frozen banana: 1/2 to 1 small banana, sliced and frozen (for creaminess; optional)
  • Ice: 1 to 1 1/2 cups, depending on how thick you like it
  • Sweetener (optional): 1–2 teaspoons maple syrup, honey, or a few drops of liquid stevia
  • Flavor boosters (optional): 1/4 teaspoon cinnamon, a pinch of sea salt, 1 teaspoon cocoa powder, or a dash of vanilla extract
  • Healthy fats (optional): 1 tablespoon peanut butter, almond butter, or 1 teaspoon MCT/coconut oil
  • Ice cubes or coffee cubes: Use coffee ice cubes if you want stronger coffee flavor without dilution

Instructions

  • Brew and cool your coffee. Make a small batch and let it chill in the fridge. Cold brew is ideal if you want less bitterness.
  • Prep your base. Add cold coffee and milk to the blender first. Liquids at the bottom help everything blend smoothly.
  • Add protein and extras. Toss in protein powder, frozen banana (if using), any sweetener, and flavor boosters. A pinch of salt enhances overall flavor.
  • Top with ice. Start with 1 cup. You can add more to thicken after the first blend.
  • Blend until silky. Start low, then increase to high for 20–30 seconds. You want a frosty, milkshake-like texture without chunks.
  • Taste and tweak. Too strong? Add a splash more milk. Too thin? Add a few ice cubes or more frozen banana. Not sweet enough? Add a touch of sweetener.
  • Serve immediately. Pour into a chilled glass. If you’re feeling extra, dust with cinnamon or cocoa and add a few coffee beans for aroma.
