Brew 1–2 shots of fresh espresso using an espresso machine, moka pot, or strong brewed coffee method of your choice. If you prefer a bolder coffee flavor that still stands out after adding ice and milk, slightly stronger coffee works best. Allow the espresso to cool for a few minutes after brewing so the hot liquid does not melt the ice too quickly and water down the drink later.

While the espresso is still warm, stir in the maple syrup along with a very small pinch of sea salt. Mix thoroughly until the maple syrup fully dissolves into the coffee. The sea salt may seem like a tiny detail, but it helps balance bitterness and enhances the rich caramel-like maple flavor, making the latte taste smoother and more coffee-shop style.

Add the high-protein milk and vanilla protein powder into a blender, shaker bottle, or milk frother. Blend or shake until the mixture becomes completely smooth, creamy, and lightly frothy with no visible clumps of protein powder remaining. Proper mixing is important because it creates a silky latte texture instead of a chalky protein drink consistency.

Fill a tall serving glass generously with ice cubes, making sure the glass is mostly full. Using plenty of ice helps keep the latte cold, creamy, and refreshing while also maintaining the beautiful layered appearance if you pour slowly.

Slowly pour the sweetened espresso mixture over the ice cubes. As the coffee hits the ice, it chills immediately while still keeping its bold flavor and smooth maple richness.

Carefully pour the creamy high-protein milk mixture into the glass over the espresso layer. Pour slowly if you want a café-style layered effect with visible separation between the dark espresso and creamy milk. The layers create a beautiful homemade coffee-shop presentation.

Gently stir the latte before drinking so the maple syrup, espresso, sea salt, and creamy protein milk combine evenly throughout the glass. This ensures every sip tastes smooth, balanced, and flavorful.

Serve immediately while the latte is cold, creamy, lightly frothy, and refreshing. For an extra coffee-shop touch, you can top the drink with a light sprinkle of flaky sea salt, cinnamon, or cold foam before serving.
