Chill your coffee. Use cold brew or brewed coffee cooled in the fridge. Cold liquid helps the shake blend thick and frosty.
Add liquids to the blender first. Pour in coffee and unsweetened milk.
This prevents clumping when you add protein powder.
Add protein and fats. Add your protein powder, heavy cream or coconut cream, and MCT oil or nut butter if using.
Sweeten and season. Add your preferred sweetener, vanilla extract, and a small pinch of salt.
Ice last. Add ice on top so the blades can pull it down evenly.
Blend until smooth. Start low, then increase to high for 20–30 seconds. Scrape down the sides if needed and blend again until creamy.
Taste and adjust. Add more sweetener for dessert vibes, more ice for thickness, or a splash of milk to thin.
Serve immediately. Pour into a tall glass. Top with a dusting of cinnamon or a drizzle of sugar-free syrup if you like.
