Equipment

  • Nespresso Machine or any espresso machine
  • Mason jar or tall glass

Ingredients
 

  • 2 ounces brewed espresso (double shot)
  • 1-2 cups ice
  • 1 teaspoon raw sugar optional
  • 1/2 teaspoon vanilla optional
  • 3/4 cup protein shake

Instructions
 

  • Fill a mason jar or glass with the ice, then brew the 2 ounces brewed espresso (double shot) directly over it. The ice chills the espresso quickly so the drink stays cold and refreshing.
  • Stir in the 1 teaspoon raw sugar (optional) and 1/2 teaspoon vanilla (optional) while the coffee is still easy to mix. The liquid should smell sweet and coffee-forward, with no sugar sitting at the bottom.
  • Pour in the 3/4 cup protein shake and stir well or seal the jar and shake until fully combined. The drink should turn one even color and look creamy from top to bottom.
  • Add more ice if desired and serve right away. The finished drink should taste smooth, cold, and balanced instead of sharp or diluted.

Notes

Make-Ahead & Storage: You can mix the coffee and protein ahead of time and keep it in an airtight container in the fridge for up to 2 days. Leave out the ice until serving to keep the flavor from diluting. Shake or stir well before drinking as some separation is normal.
Flavor Tip: To prevent a watery drink, use coffee ice cubes or start with stronger coffee like espresso or cold brew concentrate.
Sweetness Tip: Many protein shakes are already sweetened. It's a good idea to taste the drink before adding any optional sugar to avoid it becoming overly sweet.
