A quick and easy creamy iced protein coffee shake made with banana, oat milk, cold brew coffee, and vanilla protein powder. Perfect for a healthy breakfast or energizing snack.

Ingredients

Scale
  • 1 cup (8 fl oz) cold brew coffee
  • 1 large ripe banana (mashed or chopped)
  • 1 cup (8 fl oz) oat milk
  • 1 scoop (about 30 g) vanilla protein powder
  • ½ to 1 cup (4 to 8 fl oz) ice cubes
  • 12 teaspoons maple syrup or honey (optional)
  • A pinch of cinnamon or cocoa powder (optional)

Instructions

  1. Measure out 1 cup (8 fl oz) of cold brew coffee, 1 cup (8 fl oz) of oat milk, and 1 large ripe banana (peeled and chopped). Have your protein powder and ice ready.
  2. Place the cold brew, oat milk, banana, and 1 scoop (about 30 g) of vanilla protein powder into the blender jar.
  3. Add ½ to 1 cup (4 to 8 fl oz) of ice cubes depending on how thick and cold you want your shake.
  4. Drizzle in 1-2 teaspoons of maple syrup or honey if you prefer a sweeter shake (optional).
  5. Secure the lid and blend on high for about 30-45 seconds until smooth and creamy. If your blender struggles, pulse in shorter bursts and stir to combine.
  6. Check texture and taste. If it’s too thick, add a splash more oat milk and blend briefly. If the coffee flavor is too mild, add a small shot of espresso or more cold brew and blend again.
  7. Pour into your favorite glass. Sprinkle a pinch of cinnamon or cocoa powder on top for extra flavor if desired.

Notes

Use ripe bananas for natural sweetness and creamy texture. Cold brew coffee is preferred for smoothness and low acidity. Adjust ice amount for desired thickness. For vegan version, use plant-based protein powder and maple syrup or agave nectar instead of honey. Prep banana slices in advance and freeze for extra chill and creaminess. Avoid overfilling blender to prevent spills.
