Using a blender, combine the almond milk, maple syrup, vanilla, and protein powder until well combined and frothy. Set aside.
Using a large cup, fill about 1/3rd of the way with ice. Pour the cold brew over the ice. Pour the milk mixture over the cold brew. The top should be very frothy! Use a straw to gently mix the coffee.
Sprinkle with cinnamon on top, and add more ice or cold brew to taste if desired!
Notes
Cold brew is concentrated thus higher in caffeine. Diluting with milk in a latte will make it weaker, but you may have to adjust the amount of cold brew and milk to your own liking depending on your caffeine tolerance.Recommended tools: Blender
