Add the frozen raspberries and water to a small saucepan and place it over medium heat. Stir occasionally as the berries begin to soften and release their juices. After a few minutes, the raspberries will naturally break down into a thick, vibrant compote-like mixture with a rich fruity aroma. Use the back of a spoon to gently mash the berries for a smoother texture while still leaving a few small berry pieces for a homemade café-style feel. If you prefer a sweeter drink, stir in a little maple syrup, honey, or your preferred sweetener at this stage.

Once the raspberry mixture becomes thick and jammy, remove the saucepan from the heat and allow it to cool slightly while you prepare the remaining ingredients. Cooling the compote slightly helps prevent the ice from melting too quickly later. If you prefer an extra smooth latte without raspberry seeds, carefully pour the compote through a fine mesh strainer and press gently with a spoon to extract the smooth sauce.

Add the high-protein milk and vanilla protein powder into a blender. Blend for about 20–30 seconds until the mixture becomes completely smooth, creamy, and lightly frothy with no visible protein powder clumps remaining. Blending helps create a café-style silky texture and prevents the protein powder from tasting chalky.

In a small bowl or matcha cup, combine the matcha powder with warm water. Using a bamboo matcha whisk or handheld milk frother, whisk rapidly in a zig-zag motion until the matcha becomes smooth, vibrant green, and lightly foamy on top. Avoid using boiling water because extremely hot water can make matcha taste bitter instead of smooth and earthy.

Spoon the raspberry compote into the bottom of a tall serving glass and gently spread a little of the mixture around the inside edges of the glass for a beautiful layered café-style appearance. This creates vibrant raspberry streaks throughout the drink and makes the presentation look extra special.

Fill the glass generously with ice cubes, making sure the ice reaches near the top of the glass. The ice helps maintain the layered effect while keeping the drink cold and refreshing.

Slowly pour the creamy high-protein milk mixture over the ice. Pouring gradually helps keep the raspberry layer visible at the bottom while creating a creamy middle layer in the drink.

Carefully pour the whisked matcha over the top of the milk layer to create beautiful green, white, and raspberry-pink layers throughout the glass. Pour slowly for the cleanest layered appearance and most visually striking presentation.

Serve immediately while the drink is cold, creamy, and refreshing. For the best flavor in every sip, gently stir the layers together before drinking so the fruity raspberry, creamy protein milk, and earthy matcha combine evenly.
