Brew and cool your coffee. Make a small batch and let it chill in the fridge. Cold brew is ideal if you want less bitterness.
Prep your base. Add cold coffee and milk to the blender first.
Liquids at the bottom help everything blend smoothly.
Add protein and extras. Toss in protein powder, frozen banana (if using), any sweetener, and flavor boosters. A pinch of salt enhances overall flavor.
Top with ice. Start with 1 cup. You can add more to thicken after the first blend.
Blend until silky. Start low, then increase to high for 20–30 seconds.
You want a frosty, milkshake-like texture without chunks.
Taste and tweak. Too strong? Add a splash more milk. Too thin?
Add a few ice cubes or more frozen banana. Not sweet enough? Add a touch of sweetener.
Serve immediately. Pour into a chilled glass.
If you’re feeling extra, dust with cinnamon or cocoa and add a few coffee beans for aroma.
